BACKGROUND The State of California Building Standards Commission (BCS) adopts mandatory State wide Building Laws on a tri-annual basis. In January 2016, the BCS adopted the latest model codes after making amendments based on California requirements. The State Building Laws were published on July 1, 2016. Local jurisdictions have 180 days to adopt the State Building Laws and to make any amendments based on local geographic, topographic, climatic, and environmental conditions. The State Building Laws become effective statewide on January 1, 2017. Since incorporation, the City of Rosemead has adopted the County of Los Angeles Building Laws which both amends and adopts the State Building Laws and Fire Code. On November 22, 2013 the Los Angeles Board of Supervisors adopted Titles 26 (Building), 27 (Electrical), 28 (Plumbing), 29 (Mechanical), 30 (Residential), 31 (Green Building Standards), and Title 33 (Existing Building) which adopted the California Building Laws with amendments and made the necessary findings based on climatic, typographical, and geologic conditions. The adoption date by the County does not allow sufficient time for the normal City ordinance adoption process. Therefore, in order for the City's new buildings laws to become effective on January 1, 2017, the City must adopt the County ordinances by an urgency ordinance. Therefore, the City Council will be asked to adopt Urgency Ordinance No. 967, as well as introducing non-urgency Ordinance No. 968 adopting the County Codes. Copies of the County Ordinances are available in the City Clerk's Office. DISCUSSION The State adopted the same group of model building, electrical, plumbing, and mechanical codes that they adopted in 2013. The new codes are 2015 editions of the model codes (2011 for National Electrical Code) and are the result of the national three (3) year cycle of code updates and amendment processes. In this code cycle there are no new major code changes. The new Existing Building Code replaces the deleted Chapter 34 of the Building Code. Los Angeles County staff as well as the City of Rosemead staff participated in the development of specific code amendments for Los Angeles County through the Los Angeles County Region Code Program (LACRUP). This program's recommendations are the basis for the County amendments, which the City of Rosemead is adopting. The revisions to Title 15 of the Rosemead Municipal Code that are herein recommended include: BEFORE AFTER California Building Code 2013 California Building Code 2016 California Building Code 2013 California Building Code 2016 City Council Meeting December 13,2016 Page 3 of 4 Title 26 Los Angeles County Building Code Title 26 Los Angeles County Building Code 2013 2016 California Electrical Code 2013 California Electrical Code 2016 Title 27 Los Angeles County Electrical Code Title 27 Los Angeles County Electrical Code 2013 2016 California Plumbing Code 2013 California Plumbing Code 2016 Title 28 Los Angeles County Electrical Code Title 28 Los Angeles County Electrical Code 2013 2016 California Mechanical Code 2013 California Mechanical Code 2016 Title 29 Los Angeles County Mechanical Title 29 Los Angeles County Mechanical Code 2013 Code 2016 California Residential Code 2013 California Residential Code 2016 Title 30 Los Angeles County Residential Title 30 Los Angeles County Residential Code 2013 Code 2016 California Green Building Standards Code California Green Building Standards Code 2013 2016 Title 31 Los Angeles County Green Building Title 31 Los Angeles County Green Building Standards Code 2013 Standards Code 2016 California Existing Building Code 2016 Title 33 Los Angeles County Existing Building Code 2016 ENVIRONMENTAL REVIEW The proposed Ordinances (No. 967 and No. 968) are exempt from the California Environmental Quality Act pursuant to State Guidelines 15061(b)(3) as a project that has no potential for causing a significant effect on the environment.

SECTION 49. The provisions of this ordinance contain various changes, modifications, and additions to the 2016 Edition of the California Residential Code. Some of these changes are administrative in nature in that they do not constitute 33 ryOAi W881196.1 changes or modifications to requirements contained in the building standards published in the California Building Standards Code. Pursuant to California Health and Safety Code Sections 17958.5, 17958.7, and 18941.5, the Board of Supervisors hereby expressly finds that all of the changes and modifications to requirements contained in the building standards published in the Callomia Building Standards Code contained in this ordinance that are not administrative in nature are reasonably necessary because of local climatic, geological, or topographical conditions in the County of Los Angeles as more particularly described in the table set forth below. Code Condition Explanation of Amendment Section R301.1.3.2 Geological Los Angeles County Is prone to seismic activity due to the existence of active faults In the Southern California area.After the 1994 Northridge Earthquake, the Wood Frame Construction Joint Task Force recommended that the quality of woodframe construction needed to be greatly improved. The Task Force recommended that structural plans be prepared by the engineer or architect so that plan examiners, building inspectors, contractors, and special Inspectors may logically follow and construct the seismic force-resisting systems as presented in the construction documents. For buildings or structures located in Seismic Design Category Do, D1, 02, or E that are subject to a greater level of seismic forces, the requirement to have a California licensed architect or engineer prepare the construction documents is intended to minimize or reduce structural deficiencies that may cause excessive damage or Injuries in woodframe buildings. Involvement of a registered professional will minimize the occurrence of structural deficiencies such as plan and vertical Irregularities, improper shear transfer of the seismic force-resisting system, missed details or connections important to the structural system, and HOA.10000119B.1 34 Code Condition Explanation of Amendment Section the Improper application of the prescriptive requirements of the California Residential Code. R301.1.4 Geological This technical amendment Is for buildings constructed Topographical on hillsides. Due to the local topographical and geological conditions of the sites within the greater Los Angeles region and their susceptibility to earthquakes, this amendment is required to address and clarify special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and Los Angeles City Joint Task Force investigated the performance of hillside building failures after the Northridge Earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by the City and County of Los Angeles for several years. R3012.2.2.5 Geological Los Angeles County Is prone to seismic activity due to the existence of active faults in the Southern California area. Due to the high geologic activities In the Southern California area and the necessary higher level of performance required for buildings and structures, this local amendment limits the type of irregular conditions as specified In the 2016 California Residential Code. Such limitations are recommended to reduce structural damage in the event of an earthquake. The County of the Los Angeles and cities in this region have implemented these extra measures to maintain the structural Integrity of the framing of the shear walls and all associated elements when designed for high levels of seismic loads. R301.2.2.3.8 Geological Los Angeles County is prone to seismic activity due to the existence of active faults In the Southern California area. Due to the high geologic activities in the Southern California area and the necessary higher level of performance required for buildings and structures, this local amendment limits the potential anchorage and supporting frame failure resulting from additional weight. There is no limitation for weight of mechanical and plumbing fixtures and equipment in HDA.100881198.1 35 11 i Code Condition Explanation of Amendment Section the from ASCE International and the International Building Code would permit equipment weighing up to 400 Ibs, when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it Is the Intent of this amendment that a registered design professional be required to analyze if the floor support is adequate and structural! sound. Table Climatic This amendment will not allow unprotected openings R302.1(2) (openings that do not resist the spread of fire)to be in the exterior wall of a residential building that is located on a property line. This amendment is necessary due to local climatic conditions. The hot, dry weather conditions of late summer in combination with the Santa Ana winds creates an extreme fire danger. Residential buildings with unprotected openings located on a property line may permit fires to spread from the inside of the building to adjacent properties and likewise from exterior properties to the interior of the buildin•. R337.1.1 Climatic Extends the application of Chapter R337 to Include additions, alterations, and/or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to low humidity, strong winds, and dry vegetation. Additions, alterations, and/or relocated buildings have the same fire risk as new buildings. R337.1,3 Climatic Extends the application of Chapter R337 to include additions,alterations, and/or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due to the increased risk of fire caused by low humidity, strong winds, and dry vegetation. Additions, alterations, and/or relocated buildings have the same fire risk as new buildings. R337.1.3.1 Climatic Extends the application of Chapter R337 to include additions, alterations, and/or relocated buildings. Many areas of the County have been designated as Fire Hazard Severity Zones due st to rong winds, sed dry of fire caused by low humidity, 9 vegetation. Additions, alterations, and/or relocated buildings have the same fire risk as new buildings. 36 HOA.140e81196.1 Code Condition Explanation of Amendment Section R337.3.5.2 Climatic Disallows the use of wood-shingle/wood-shake roofs due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation. R337.3.5.2.2 Climatic Disallows the use of wood-shingle/wood-shake roofs due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation. R337.4.3 Climatic Disallows the use of wood-shingle/wood-shake roofs due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in High Fire Severity Zones. R337.5.2 Climatic Disallows the use of wood-shingle/wood-shake roofs and requires the use of Class A roof covering due to the increased risk of fire in the County caused by low humidity, strong winds, and dry vegetation in High Fire Severity Zones. R401.1 Geological Los Angeles County is prone to seismic activity due to the existence of active faults In the Southern California area.Wood foundations, even those that are preservative-treated, encounter a higher risk of deterioration when contacting the adjacent ground. The required seismic anchorage and transfer of lateral forces into the foundation system necessary for 2-story structures and foundation walls could become compromised at varying states of wood decay. In addition, global structure overturning moment and sliding resistance Is reduced when utilizing wood foundations as opposed to conventional concrete or masonry systems. However, non-occupied, single-story storage structures pose significantly less risk to human safety and may utilize the wood foundation guidelines specified in this Chapter. R403.1.2 Climatic Los Angeles County is prone to seismic activity due R403.1.3.6 Geological to the existence of active faults in the Southern R403.1.5 California area. These proposed amendments require Figure minimum reinforcement in continuous footings and R403.1.5 stepped footings to address the problem of poor performance of plain or under-reinforced footings during a seismic event. These amendments implement the recommendations of SEAOSC and the Los Angeles City Joint Task Force resulting from their Investigation of the 1994 Northridge Earthquake. HOA.100B81186.1 37 Code Condition Explanation of Amendment Section Interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non-structural concrete slab floors, wood • floors, etc. Requiring Interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. R4042 Climatic No substantiating data has been provided to show Geological that wood foundations are effective in supporting structures and buildings during a seismic event while being subject to deterioration caused by the presence of water and other materials detrimental to wood foundations in the soil. Wood foundations, when they are not properly treated and protected against deterioration, have performed very poorly nd have led to slope failures. Most contractors are typically accustomed to construction in dry weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. With the higher seismic demand placed on buildings and structures in this region, coupled with the dryer weather conditions, it is the intent of this amendment to reduce or eliminate potential problems resulting from the use of wood footings and foundations. R501.1 Geological Due to the high geologic activities in the Southern California area and the necessary higher level of performance required for buildings and structures, this local amendment limits the potential anchorage and supporting frame failure resulting from additional weight. There is no limitation for weight of mechanical and plumbing fixtures and equipment in the International Residential Code. Requirements from ASCE 7 and the International Building Code would permit equipment weighing up to 400 lbs. when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this 38 ryeA1008B}196.1 Code Condition Explanation of Amendment Section proposed amendment that a registered design professional be required to analyze if the floor support is ado,uate and structural) sound. R503.2.4 Geological Section R502.10 of the Code does not provide any Figure prescriptive criteria to limit the maximum floor R503.2.4 opening size nor does Section R503 provide any details to address the Issue of shear transfer near larger floor openings. With the higher seismic demand placed on buildings and structures in this region, it is important to ensure that a complete load path is provided to reduce or eliminate potential damage caused by seismic forces. Requiring blocking with metal ties around larger floor openings and limiting opening size is consistent with the r=•uirements of Section R301.2.22.5. R602.3.2 Geological Los Angeles County Is prone to seismic activity due to the existence of active faults in the Southern California area.The County of the Los Angeles and cities In this region have taken extra measures to maintain the structural Integrity of the framing of the shear walls when designed for high levels of seismic loads by eliminating single top plate construction. The performance of modern day braced wall panel construction Is directly related to an adequate load path extending from the roof diaphragm to the foundations stem. Table Geological Los Angeles County is prone to seismic activity due R602.3(1) to the existence of active faults In the Southern Table California area. In September 2007, limited cyclic R602.3(2) ar nChpteStructural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed wood structural shear panels. The test results of the stapled wood structural shear panels demonstrated lower strength and drift than the nailed wood structural shear panel test results. Therefore, the use of staples as fasteners for shear walls sheathed with other materials shall not be permitted without being substantiated b c clic testin.. 39 HOAJOOBB1196.1 Table Geological Due to the high geologic activities in the Southern R602.10.3(3) California area and the necessary higher level of performance on buildings and structures, this local amendment continues to reduce/eliminate the allowable shear values for shear walls sheathed with lath, plaster or gypsum board. The poor performance of such shear walls sheathed with other materials In the 1994 Northridge Earthquake was investigated by SEAOSC and the Los Angeles City Joint Task Force. The County of the Los Angeles and cities in this region have taken extra measures to maintain the structural integrity of the framing of the shear walls when designed for high levels of seismic loads, Table Geological 3/8"thick 3 ply-plywood shear walls experienced R602.10.4 many failures during the Northridge Earthquake. This proposed amendment specifies minimum WSP sheathing thickness and nail size and spacing so as to provide a uniform standard of construction to improve the performance level of buildings and structures given the potential for higher seismic demands placed on buildings or structure in this region. This proposed amendment reflects the recommendations by SEAOSC and the Los Angeles City Joint Task Force following the 1994 Northridge Earthquake. In September 2007, cyclic testing data was provided to the Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels underperformed nailed wood structural shear panels. Test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results. Table Geological Los Angeles County Is prone to seismic activity due R602.10.5 to the existence of active faults in the Southern California area, The poor performance of such shear walls sheathed in the 1994 Northridge Earthquake was investigated by SEAOSC and the Los Angeles City Joint Task Force. The County of the Los Angeles and cities In this region have taken extra measures to maintain the structural integrity with respect to the"maximum shear wall aspect ratios" of the framing of the shear walls when designed for high levels of seismic loads. This proposed amendment is HOA.1008B11D6.1 40 consistent with the shear wall aspect ratio provision of Section 4.3.4 of AWC SDPWS-2015. Figure Geological 3/8"thick 3 ply-plywood shear walls experienced R602.10.6.1 many failures during the Northridge Earthquake. The poor performance of shear walls in the 1994 Northrldge Earthquake was Investigated by SEAOSC and the Los Angeles City Joint Task Force. Box nails were observed to cause massive and multiple failures of the typical 3/8"thick 3 ply-plywood during the Northridge Earthquake. The County of the Los Angeles and cities in this region have taken extra measures to maintain the structural Integrity of the framing of the shear walls when designed for high levels of seismic loads. The performance of modern day braced wall panel construction is directly related to an adequate load path extending from the roof diaphragm to the foundation system. Figure Geological 3/8°thick 3 ply-plywood shear walls experienced R802.10.6.2 many failures during the Northridge Earthquake. The poor performance of such shear walls sheathed in the 1994 Northridge Earthquake was investigated by SEAOSC and the Los Angeles City Joint Task Force. The County of the Los Angeles and cities In this region have taken extra measures to maintain the structural integrity of the framing of the shear walls when designed for high levels of seismic loads. Box nails were observed to cause massive and multiple failures of the typical 3/8-inch thick plywood during the Northridge Earthquake. The proposal to change the minimum lap splice requirement is consistent with Section 12.16.1 of ACI 318-11. This proposed amendment is a continuation of an amendment adopted during the previous Code adoption cycles. Figure Geological 318°thick 3 ply-plywood shear walls experienced R602.10.8.4 many failures during the Northrldge Earthquake. The poor performance of such shear walls sheathed in the 1994 Northridge Earthquake was Investigated by SEAOSC and the Los Angeles City Joint Task Force. The County of the Los Angeles and cities in this region have taken extra measures to maintain the structural Integrity of the framing of the shear walls when designed for high levels of seismic loads. The proposal in which'Washers shall be a minimum of 0.229 inch by 3 Inches by 3 inches in size" is HOh1008B11913.1 41 consistent with Section R602.11.1 of the California Residential Code and Section 2308.3.2 of the • California Building Code. This proposed amendment Is a continuation of an amendment adopted during the previous Code adoption cycle. R806.4.4 Geological Los Angeles County is prone to seismic activity due to the existence of active faults in the Southern California area. The addition of the word "or"will prevent the use of unreinforced parapets in Seismic Design Category Do, Di or D2, or on townhouses in Seismic Design Category C. R606.12.2.2. Geological Los Angeles County Is prone to seismic activity due 3 to the existence of active faults in the Southern California area. Reinforcement using longitudinal wires for buildings and structures located in high seismic areas are not as ductile as deformed rebar. Having vertical reinforcement closer to the ends of masonry walls help to improve the seismic performance of masonry buildings and structures. R803.2.4 Geological Section R802 of the Code does not provide any prescriptive criteria to limit the maximum size of roof openings, nor does Section R803 provide any details to address the issue of shear transfer near larger roof openings. With the higher seismic demand placed on buildings and structures In this region, it Is important to ensure that a complete load path is provided to reduce or eliminate potential damage caused by seismic forces. Requiring blocking with metal ties around larger roof openings and limiting the size of openings Is consistent with the requirements of Section R301.2.2.2.5. R1001.3.1 Geological Los Angeles County Is prone to seismic activity due to the existence of active faults in the Southern California area. The performance of fireplaces/chimneys without anchorage to the foundation has been observed to be inadequate during major earthquakes. The lack of anchorage to the foundation results in overturn or displacement. SECTION 49.

Today the Chapter has grown to over eighty-nine Southern California jurisdictions, plus consulting firms and other members of the construction industry. ICBO merged with two other building official organizations to create the International Code Council. The Los Angeles Basin Chapter officially became an ICC Chapter in December 2002. The Los Angeles Basin Chapter has been very active throughout the years in leading an effort to create uniformity of building codes and regulations in the greater Los Angeles region as well as addressing policy issues of interest to building officials and the construction industry. One such effort to promote uniformity of building regulations is through the Los Angeles Regional Uniform Code Program ( LARUGP"). The LARUCP program began in July 1999 with the purpose of developing uniform interpretations and handouts to serve as guidelines for building officials, contractors, engineers and architects in the consistent application of the codes.The mission of the program was to minimize the number of and to develop unifomiity in local code amendments to the California codes for adoption by jurisdictions in the greater Los Angeles region and beyond. Leading the efforts to creating uniformity of building codes and regulations within the region are the dedicated members of the Los Angeles County Building and Safety Division, City of Los Angeles Department of Building and Safety, City of Long Beach Building and Safety Bureau, and other jurisdictional members and partners in the greater Los Angeles region. Through the coordination of the ICC Los Angeles Basin Chapter's Fire-Life Safety Committee, Structural Committee, Green and Sustainability Committee, and Administration Committee,the following regulatory streamlining tasks to be completed are: 1. Create uniformity of building standards code that can be adopted in most of the jurisdictions in the greater Los Angeles region; 2. Reduce the total number of local technical amendments to the model code in the greater Los Angeles region; 3. Receive support from many, if not all, of the 89 jurisdictions in the greater Los Angeles region; 4. Obtain active participation from a majority of the jurisdictions in the greater Los Angeles region in formulating and implementing the program, and 5. With construction valuation of over$5 billion in the region, conservatively assuming that the program produces a 1%construction cost savings, achieve an estimated cost saving of$50 million per year in the greater Los Angeles region. DISCUSSION Sections 13145.3, 17922, 17958 and 18941.5 of the California Health and Safety Code requires that the latest California Building Standards Codes apply to local construction 180 days after they become effective at the State level. The California Building Standards Commission has adopted the 2016 Edition of the California Building Code, California Residential Code, and California Green Building Standards Code. State Law requires that these Codes become effective at the local level on January 1, 2017. Sections 17958.5 and 17958.7 of the California Heakh and Safety Code requires that local code amendments to the California Building Standards Codes and other regulations, including but not limited to, green building standards, be enacted only when an express finding is made that such modifications or changes are reasonably necessary because of local climatic, geological, topographical or environmental conditions. 2016 Edition of the California Building Code Page 2 of 118 2016 Edition of the California Residential Code Final Version:08/0512016 2016 Edition of the California Green Building Standards Code Updated Version'.08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM The ICC Los Angeles Basin Chapter's Structural Committee and Green Building Standards Committee are recommending that the 2016 Edition of the LARUCP Recommended Code Amendments contained in this document, some of which continues amendments enacted during the previous code adoption cycle, be considered for local code adoption for the following reasons: 1. To protect the community within the greater Los Angeles region from a vast array of fault systems capable of producing major earthquakes and/or climate systems capable of producing major winds, fire and rain related disaster. 2. To ensure and encourage energy efficiency and sustainable practices are incorporated into building designs and constructions. The 2016 Edition of the fARUCP Recommended Code Amendments have been widely circulated and discussed over the past several months with various local jurisdictional members, SEAOSC Building Code Committee, design professionals in the construction industry, and other interested groups or individuals. The proposed code language along with the reasons and findings are detailed in this document for each of the recommended code amendments to the 2016 Edition of the California Building Standards Code. STATEMENT ON USE OF DOCUMENT The primary purpose of the ICC Los Angeles Basin Chapter's Committees is to serve and benefit its members.To this end,the Committees provide a forum for the exchange, consideration, and discussion of ideas and proposals that are relevant to the construction industry and the consensus of which forms the basis for the proposed amendments contained in this document.

Concrete and clay tile shall be installed only over solid 'r spaced structural sheathing boards. RATIONALE: Section 1507.3.1 is amended to require concrete and clay tiles to be installed only over solid structural sheathing boards. The change is necessary because there were numerous observations of tile roofs pulling away from wood framed buildings following the 1994 Northridge Earthquake. The SEAOSC/LA City Post Northridge Earthquake committee findings indicated significant problems with tile roofs was due to inadequate design and/or construction. Therefore, the amendment is needed to minimize such occurrences in the event of future significant earthquakes. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake, the 1987 Whittier Narrows Earthquake, the 1971 San Fernando Earthquake and the 1933 Long Beach Earthquake. This amendment will reduce the failure of concrete and clay tile roofs during a significant earthquake and is in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Code Page 10 01118 2016 Edition of the California Residential Code Final Version:0010512016 2016 Edition of the California Green Building Standards Code Updated Version:0 8/2312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 16-01. Section 1613.5.2 is added to Chapter 16 of the 2016 Edition of the California Building Code to read as follows: 1613.5.2 Structural Separation. Modify ASCE 7 Section 12.12.3 Equation 12.12-1 as follows: = Ca6R,. (12.12-1) u RATIONALE: The inclusion of the importance factor in this equation has the unintended consequence of reducing the minimum seismic separation distance for important facilities such as hospitals, schools, police and fire stations from adjoining structures. The proposal to omit the importance factor from Equation 12.12-1 will ensure that a safe seismic separation distance is provided.This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake, the 1987 Whittier Narrows Earthquake, the 1971 San Fernando Earthquake and the 1933 Long Beach Earthquake. The proposed modification to omit the importance factor in the equation ensures that a safe seismic separator distance is maintained for important facilities from adjoining structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code. • 2015 Edition of the California Building Code Page 11 of 118 2016 Edition of the California Residential Code Final Version:06/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:06/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 16-02. Section 1613.5.3 is added to Chapter 16 of the 2016 Edition of the California Building Code to read as follows: 1613.5.3 Values for Vertical Combinations. Modify ASCE 7 Section 12.2.3.1 Exception 3 as follows: 3. Detached one-and two-family dwellings up to two stories in height of light frame construction, RATIONALE: Observed damages to one and two family dwellings of light frame construction after the Northridge Earthquake may have been partially attributed to vertical irregularities common to this type of occupancy and construction. In an effort to improve quality of construction and incorporate lesson learned from studies after the Northridge Earthquake, the proposed modification to ASCE 7-10 Section 12.2.3.1 Exception 3 by limiting the number of stories and height of the structure to two stories will significantly minimize the impact of vertical irregularities and concentration of inelastic behavior from mixed structural systems. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification to limit mixed structural system to two stories is intended to improve quality of construction by reducing potential damages that may result from vertical irregularities of the structural system in buildings subject to high seismic load and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Code Page 12 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 16-03. Section 1613.5.4 is added to Chapter 16 of the 2016 Edition of the California Building Code to read as follows: 1613.5.4 Wood Diaphragms.Modify ASCE 7 Section 12.11.2.2.3 as follows: 12.11.2.2.3 Wood Diaphragms. In wood diaphragms, the continuous ties shall be in addition to the diaphragm sheathing. Anchorage shall not be accomplished by use of toe nails or nails subject to withdrawal nor shall wood ledgers or framing be used in cross-grain bending or cross-grain tension. The diaphragm sheathing shall not be considered effective as providing ties or struts required by this section. For structures assigned to Seismic Design Category D, 6 or F wood diaphragms supporting concrete or masonry walls shall comply with the following: 1. The spacing of continuous ties shall not exceed 40 feet. Added chords of diaphragms may be used to form subdiaphraoms to transmit the anchorage forces to the main continuous crossties. 2, The maximum diaphragm shear used to determine the depth of the subdiaphragm shall not exceed 75%of the maximum diaphragm shear. RATIONALE: A joint Structural Engineers Association of Southern California (SEAOSC), Los Angeles County and Los Angeles City Task Force investigated the performance of concrete and masonry construction with flexible wood diaphragm failures after the Northridge earthquake. It was concluded at that time that continuous ties are needed at specified spacing to control cross grain tension in the interior of the diaphragm. Additionally, there was a need to limit subdiaphragm allowable shear loads to control combined orthogonal stresses within the diaphragm. Recognizing the importance and need to continue the recommendation made by the task force while taking into consideration the improve performances and standards for diaphragm construction today, this proposal increases the continuous be spacing limit to 40 ft in lieu of 25 ft and to use 75%of the allowable code diaphragm shear to determine the depth of the sub- diaphragm in lieu of the 300 plf and is deemed appropriate and acceptable. Due to the frequency of this type of failure during the past significant earthquakes, various jurisdictions within the Los Angeles region have taken this additional step to prevent roof or floor diaphragms from pulling away from concrete or masonry walls. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake. The proposed modification to require special anchorage of the diaphragm to the wall and limit the allowable shear will address special needs for concrete and masonry construction with flexible wood diaphragm and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Code Page 13 of 118 2016 Edition of the California Residential Code Final Version:0810512016 2016 Edition of the California Green Building Standards Code Updated Version:08123/2018 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 16-04. Section 1613.5.5 is added to Chapter 16 of the 2016 Edition of the California Building Code to read as follows: 1613.5.5 Maximum Soa Value In Determination of C, and E . Modify ASCE 7 Section 12.8.1.3 as follows: Section 11.4.1 or 11.47. 12.8.1.3 Maximum S., Value in Determination of C and E . The value of Cs and E„are permitted to be calculated using a value of Sos equal to 1.0 but not less than 70%of S"; as defined in Section 11.4.4, provided that all of the following criteria are met: 1. The structure does not have irregularities,as defined in Section 12,3.2' 2. The structure does not exceed five stories above the lower of the base or grade plane as defined in Section 11.2, and, where present, each mezzanine level shall be considered a story for the purpose of this limit; 3. The structure has a fundamental period, T,that does not exceed 0.5 seconds as determined using Section 12.8.2: 4. The structure meets the requirements necessary for the redundancy factor, p to be permitted to be taken as 1.0,in accordance with Section 12.3.4.2; 5, The site soil properties are not classified as Site Classes E or F, as defined in Section 11.4.2; and 6. The structure is classified as Risk Category I or II, as defined in Section 1.5.1. RATIONALE: Amendment in the California Building Code is made to be consistent with ASCE 7-16, and is further amended herein to be consistent with ASCE 7-16 Supplement1. The modification is necessary to avoid misinterpretation on the intent of the five story limit for which the Sos cap is applicable where there is flexible structure above a rigid podium base. The addition of "grade plane" clarifies the intent that the base is measured from the lowest structure in those instances where there is a vertical combination of two Systems. Many of such combinations of systems will not satisfy exclusion 1, in which the structure must meet the definition of "regular" based on ASCE 7 Section 12.3.2. This modification provides safe design requirements in the selection of building period to calculate seismic base shear in building design accounting for dynamic story mass distribution throughout the inelastic range of ground motion. This amendment does not prevent designing of five levels of light frame wood construction on top of a concrete podium by using the calculated Sos without the 70%cap. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings constructed over and near a vast array of fault systems capable of producing major earthquakes, Including but not limited to the 1994 Northridge Earthquake. Currently mezzanines do not have to be considered as a floor level for Heights and Areas limits of Chapter 5 of the IBC.When applying the story height allowing Sos to be equal to 1.0, but not less than 70% of calculated SOS, the five story height limitation needs to consider mezzanines as individual floor levels due to added mass, overturning forces and variation in shear wall stiffness at the mezzanine floor levels, and therefore needs to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Cede Page 14 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:0623/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 16-05. Section 1613.7 Is added to Chapter 16 of the 2016 Edition of the California Building Code to read as follows: 1613.7 Seismic Design Provisions for Hillside Buildings. 1613.7.1 Purpose.The purpose of this section is to establish minimum regulations for the design and construction of new buildings and additions to existing buildings when constructing such buildings on or into slopes steeper than one unit vertical in three units horizontal (33.3%). These regulations establish minimum standards for seismic force resistance to reduce the risk of injury or loss of life in the event of earthquakes. 1613.7.2 Scope. The provisions of this section shall apply to the design of the lateral-force-resisting system for hillside buildings at and below the base level diaphragm. The design of the lateral-force- resisting system above the base level diaphragm shall be in accordance with the provisions for seismic and wind design as required elsewhere in this division. Exception: Non-habitable accessory buildings and decks not supporting or supported from the main building are exempt from these regulations. 16117.3 Definitions. For the purposes of this section certain terms are defined as follows: BASE LEVEL DIAPHRAGM is the floor at, or closest to, the top of the highest level of the foundation. DIAPHRAGM ANCHORS are assemblies that connect a diaphragm to the adlacent foundation at the uphill diaphragm edge. DOWNHILL DIRECTION is the descending direction of the slope approximately perpendicular to the slope contours. FOUNDATION is concrete or masonry which supports a building, including footings, stern walls, retaining walls, and grade beams. FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION is a foundation running downhill and approximately perpendicular to the uphill foundation. HILLSIDE BUILDING is any building or portion thereof constructed on or into a slope steeper than one unit vertical in three units horizontal (33.3%). If only a portion of the building is supported on or into the slope these regulations apply to the entire building. PRIMARY ANCHORS are diaphragm anchors designed for and providing a direct connection as described in Sections 1613.7.5 and 1613.7.7.3 between the diaphragm and the uphill foundation. SECONDARY ANCHORS are diaphragm anchors designed for and providing a redundant diaphragm to foundation connection, as described in Sections 16117.6 and 1613.7.7.4. UPHILL DIAPHRAGM EDGE is the edge of the diaphragm adjacent and closest to the highest ground level at the perimeter of the diaphragm. UPHILL FOUNDATION is the foundation parallel and closest to the uphill diaphragm edge. 1613.7.4 Analysis and Design. 1613.7.4.1 General. Every hillside building within the scope of this section shall be analyzed, designed, and constructed in accordance with the provisions of this division. When the code- 2016 Edition of the California Building Code Page 15 01118 2016 Edition of the CBllfomia Residential Code Final Version:08105/2016 2016 Edition of the California Green Building Standards Code Updated Version:0812312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM prescribed wind design produces greater effects, the wind design shall govern, but detailing requirements and limitations prescribed in this and referenced sections shall be followed. 1613.7.4.2 Base Level Diaphragm-Downhill Direction. The following provisions shall apply to the seismic analysis and design of the connections for the base level diaphragm in the downhill direction. 1613.7.4.2.1 Base for Lateral Force Design Defined. For seismic forces acting in the downhill direction, the base of the building shall be the floor at or closest to the top of the highest level of the foundation. 1613.7.4.2.2 Base Shear. In developing the base shear for seismic design, the response modification coefficient (R) shall not exceed 5 for bearing wall and building frame systems The total base shear shall include the forces tributary to the base level diaphragm including forces from the base level diaphragm. 1613.7.5 Base Shear Resistance-Primary Anchors. 1613.7.5.1 General. The base shear in the downhill direction shall be resisted through primary anchors from diaphragm struts provided in the base level diaphragm to the foundation. 1613.7.5.2 Location of Primary Anchors. A primary anchor and diaphragm strut shall be provided in line with each foundation extending in the downhill direction. Primary anchors and diaphragm struts shall also be provided where interior vertical lateral-force-resisting elements occur above and in contact with the base level diaphragm. The spacing of primary anchors and diaphragm struts or collectors shall in no case exceed 30 feet(9144 mm). 1613.7.5.3 Design of Primary Anchors and Diaphragm Struts. Primary anchors and diaphragm struts shall be designed in accordance with the requirements of Section 1613.7.8. 16131.5.4 Limitations. The following lateral-force-resisting elements shall not be designed to resist seismic forces below the base level diaphragm in the downhill direction: 1. Wood structural panel wall sheathing, 2. Cement plaster and lath 3. Gypsum wallboard, and 4. Tension only braced frames. Braced frames designed in accordance with the requirements of Section 2205.2.1.2 may be used to transfer forces from the primary anchors and diaphragm struts to the foundation provided lateral forces do not induce flexural stresses in any member of the frame or in the diaphragm struts. Deflections of frames shall account for the variation in slope of diagonal members when the frame is not rectangular. 1613.7.6 Base Shear Resistance-Secondary Anchors. 1613.7.6.1 General. In addition to the primary anchors required by Section 1613.7.5, the base shear in the downhill direction shall be resisted through secondary anchors in the uphill foundation connected to diaphragm struts in the base level diaphragm. Exception: Secondary anchors are not required where foundations extending in the downhill direction spaced at not more than 30 feet(9144 mm) on center extend up to and are directly connected to the base level diaphragm for at least 70%of the diaphragm depth. 1613.7.6.2 Secondary Anchor Capacity and Spacing.

RATIONALE: Due to the difficulty of fire suppression vehicles accessing winding and narrow hillside properties and the probabilities for future earthquakes in the Los Angeles region, this technical amendment is required to address the special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and both the Los Angeles County and Los Angeles City Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Topographical and Geological Conditions—The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the topography within the Los Angeles region includes significant hillsides with narrow and winding access that makes timely response by fire suppression vehicles challenging and difficult.

Minimum design and installation standards for suspended ceilings shall be determined in accordance with the requirements of Section 2506.2.1 of this Code and this section. 1613.8.1 Scope.This part contains special requirements for suspended ceilings and lighting systems. Provisions of Section 13.5.6 of ASCE 7 shall apply except as modified herein. 16118.2 General. The suspended ceilings and lighting systems shall be limited to 6 feet(1828 mm) below the structural deck unless the lateral bracing is designed by a licensed engineer or architect. 1613.8.3 Sprinkler Heads. All sprinkler heads (drops) except fire-resistance-rated Floor/ceiling or roof/ceiling assemblies, shall be designed to allow for free movement of the sprinkler pipes with oversize rings, sleeves or adaptors through the ceiling tile. Sprinkler heads and other penetrations shall have a 2 inch (50mm)oversize ring sleeve, or adapter through the ceiling tile to allow for free movement of at least 1 inch (25mm) in all horizontal directions. Alternatively, a swing joint that can accommodate 1 inch (25 mm) of ceiling movement in all horizontal directions is permitted to be provided at the top of the sprinkler head extension. Sprinkler heads penetrating fire-resistance-rated floor/ceiling or roof/ceiling assemblies shall comply with Section 714 of this Code. 1613.8.4 Special Requirements for Means of Egress.

RATIONALE: The California Building Code has little to no information regarding the safe design and construction requirements for ceiling suspension systems subject to seismic loads. It is through the experience of prior earthquakes, such as the Northridge Earthquake, that this amendment is proposed so as to minimize the amount of bodily and building damage within the spaces in which this type of ceiling will be installed. This proposed amendment complements ASCE 7-10 Chapter 13 Section 13.5.6.2.2 and the cited reference to ASTM E580.The amended requirements retained herein are a continuation of portions of an amendment adopted during the previous code adoption cycles.

Section 1704.6 of the 2016 Edition of the California Building Code is amended to read as follows: 1704.6 Structural Observations. Where required by the provisions of Section 1704.6.1 or 1704.6.2,111e owner or the owners authorized agent shall employ a tructural observer to perform structural observations. Structural observation does not include or waive the responsibility for the inspections in Section 110 or the special inspections in Section 1705 or other section of this code. The structural observer shall be one of the following individuals: 1. The registered design professional responsible for the structural design,or 2. A registered design professional designated by the registered design professional responsible for the structural design. Prior to the commencement of observations, the structural observer shall submit to the building official a written statement identifying the frequency and extent of structural observations. . The owner or owners authorized agent shall coordinate and call a preconstrucfion meeting between the structural observer, contractors affected subcontractors and special inspectors. The structural observer shall preside over the meeting. The purpose of the meeting shall be to identify the major structural elements and connections that affect the vertical and lateral load resisting systems of the structure and to review scheduling of the required observations.A record of the meeting shall be included in the report submitted to the Building Official. Observed deficiencies shall be reported in writing to the owner or owner's authorized agent, special inspector contractor and the Budding Official. Upon the form prescribed by the Bonding Official, the structural observer shall submit to the Building Official a written statement at each significant construction stage stating that the site visits have been made and identifying any reported deficiencies which to the best of the structural observer's knowledge, have not been resolved. A final report by the structural observer which states that all observed deficiencies have been resolved is required before acceptance of the work by the Building Official. RATIONALE: The language in Section 1704.6 of the California Building Code permits the owner to employ any registered design professional to perform structural observations with minimum guideline. However, it is important to recognize that the registered design professional responsible for the structural design has thorough knowledge of the building he/she designed. By requiring the registered design professional responsible for the structural design or their designee who were involved with the design to observe the construction, the quality of the observation for major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. Additional requirements are provided to help clarify the role and duties of the structural observer and the method of reporting and correcting observed deficiencies to the building official. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles.

Exception 3 of Section 1705.12 of the 2016 Edition of the California Building Code is amended to read as follows: 1705.12 Special inspections for seismic resistance. Special inspections for seismic resistance shall be required as specified in Sections 1705.12.1 through 1705.12.9, unless exempted by the exceptions of Section 1704.2. Exception: The special inspections specified in Sections 1705.12.1 through 1705.12.9 are not required for structures designed and constructed in accordance with one of the following: 1. The structure consists of light-frame construction; the design spectral response acceleration at short periods, Sgs, as determined. in Section 1613.3.4. does not exceed 0.5; and the building height of the structure does not exceed 35 feet(10 666 mm) 2. The seismic force-resisting system of the structure consists of reinforced masonry or reinforced concrete; the design spectral response acceleration at short periods, Soso as determined in Section 1613,3.4, does not exceed 0,5; and the building height of the structure does not exceed 25 feet(7620 mm) 3. The structure Is a detached one- or two-family dwelling not exceeding two stories above grade plane, is not assigned to Seismic Design Category D. E or F and does not have any of the following horizontal or vertical irregularities in accordance with Section 12.3 of ASCE 7: 3.1 Torsional or extreme torsional irregularity. 3.2 Nonparallel systems irregularity. 3.3 Stiffness-soft story or stiffness-extreme soft story irregularity. 3,4 Discontinuity in lateral strength-weak story irregularity. RATIONALE: In Southern California, very few detached one- or two-family dwellings not exceeding two stories above grade plane are built as 'box-type'' structures, especially those in hillside areas and near the oceanfront. Many steel moment frames or braced frames and/or cantilevered columns within buildings can still be shown as 'regular" structures by calculations. With the higher seismic demand placed on buildings and structures in this region, the language in Section 1705.12 Exception 3 of the California Building Code would permit many detached one-or two-family dwellings not exceeding two stories above grade plane with complex structural elements to be constructed without the benefit of special inspections. By requiring special inspections, the quality of major structural elements and connections that affect the vertical and lateral load resisting systems of the structure will greatly be increased. The exception should only be allowed for detached one-or two-family dwellings not exceeding two stories above grade plane assigned to Seismic Design category A, B and C.

Section 1807.1.4 of the 2016 Edition of the California Building Code is amended to read as follows: 1807.1.4 Permanent wood foundation systems. Permanent wood foundation systems shall be designed and installed in accordance with AWC PWF. Lumber and plywood shall be treated in accordance with AWPA U1 (Commodity Specification A, Use Category 46 and Section 5.2)and shall be identified in accordance with Section 2303.1.9.1. Permanent wood foundation systems shall not be used for structures assigned to Seismic Design Category D, E or F. RATIONALE: No substantiating data has been provided to show that wood foundation systems are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effects of constant moisture in the soil and wood-destroying organisms. Wood foundation systems not properly treated and protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic events and wet applications. The proposed amendment takes the precautionary steps to reduce or eliminate potential problems that may result in using wood foundation systems that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood-destroying organisms. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Climatic and Geological Conditions—The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the 1994 Northridge Earthquake.

Prescriptive design of foundation walls shall not be used for structures assigned to Seismic Design Category D,E or F. RATIONALE: With the higher seismic demand placed on buildings and structures in this region, it is deemed necessary to take precautionary steps to reduce or eliminate potential problems that may result by following prescriptive design provisions that does not take into consideration the surrounding environment. Plain concrete performs poorly in withstanding the cyclic forces resulting from seismic events.

Such footings shall be treated in accordance with AWPA Ul (Commodity Specification A, Use Category 4B). Treated timbers are not required where placed entirely below permanent water level, or where used as capping for wood piles that project above the water level over submerged or marsh lands.

Timber footings, when they are not properly treated and protected against deterioration, have performed very poorly. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic event and wet applications.

Section 1905.1 is amended and Sections 1905.1.9 thru 1905.1.11 are added to '.. Chapter 19 of the 2016 Edition of the California Building Code to read as follows: 1905.1 General. The text of ACI 318 shall be modified as indicated in Sections 1905.1.1 through 4908:141905.1.11. 1905.1.9 ACI 318, Section 18.7.5. Modify ACI 318, Section 18.7.5 by adding Section 18.7.5.7 and 18.7.5.8 as follows: 18.7 5.7 Where the calculated point of centrabexuro is not within the middle half of the member clear height, provide transverse reinforcement as specified in ACI 318 Sections 18.7.5.1, Items (a) through (c), over the full height of the member. 18.7.5.8—At any section where the design strength, 0P,, of the column is less than the sum of the shears V. computed in accordance with ACI 318 Sections 18.7,6.1 and 18.6.5.1 for all the beams framing into the column above the level under consideration, transverse reinforcement as specified in ACI 318 Sections 18.7.5.1 through 18.7.5.3 shall be provided For beams framing into opposite sides of the column, the moment components are permitted to be assumed to be of opposite sign. For the determination of the design strength, mPo of the column, these moments are permitted to be assumed to result from the deformation of the frame in any one principal axis. 1905.1.10 ACI 318, Section 18.10.4. Modify ACI 315, Section 18.10.4. by adding Section 18.10.4.6 as follows: 18.10.4.6—Walls and portions of walls with P„> 0.35P„shall not be considered to contribute to the calculated shear strength of the structure for resisting earthquake-induced forces. Such walls shall conform to the requirements of ACI 318 Section 18.14. 1905.1.11 ACI 318, Section 18.12.6.

RATIONALE: This amendment is intended to carry over critical provisions for the design of concrete columns in moment frames from the legacy 1997 Uniform Building Code. Increased confinement is critical to the integrity of such columns and these modifications ensure that it is provided when certain thresholds are exceeded. In addition, this amendment carries over from the legacy 1997 Uniform Building Code a critical provision for the design of concrete shear walls_ It essentially limits the use of very highly gravity-loaded walls in being included in the seismic load resisting system, since their failure could have catastrophic effect on the building. Furthermore, this amendment was incorporated in the code based on observations from the 1994 Northridge Earthquake. Rebar placed in very thin concrete topping slabs have been observed in some instances to have popped out of the slab due to insufficient concrete coverage.This modification ensures that critical boundary and collector rebars are placed in sufficiently thick topping slab to prevent buckling of such reinforcements. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. 2018 Edition of the California Building Code Page 38 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of Oe California Green Building Standards Code Updated Version.08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM FINDINGS: Local Geological Conditions — The greater Las Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake.

Exception:Staples may be used to resistor transfer seismic forces when the allowable shear values are substantiated by cyclic testing and approved by the building official. RATIONALE: Due to the high geologic activities in the Southern California area and the expected higher level of performance on buildings and structures, this proposed local amendment limit the use of staple fasteners in resisting or transferring seismic forces, In September 2007, limited cyclic testing data was provided to the ICC Los Angeles Chapter Structural Code Committee showing that stapled wood structural shear panels do not exhibit the same behavior as the nailed wood structural shear panels. The test results of the stapled wood structural shear panels appeared much lower in strength and drift than the nailed wood structural shear panel test results. Therefore,the use of staples as fasteners to resist or transfer seismic forces shall not be permitted without being substantiated by cyclic testing.This proposed amendment is a continuation of a similar amendment adopted during previous code adoption cycles.

Wood installed in retaining or crib walls shall be preservative treated in accordance with AWPA U1 for soil and fresh water use.Wood shall not be used in retaining or crib walls for structures assigned to Seismic Design Category D, E or F. RATIONALE: No substantiating data has been provided to show that wood used in retaining or crib walls are effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood-destroying organisms. Wood used in retaining or crib walls, when they are not properly treated and protected against deterioration, have performed very poorly.

Section 2305.4 is added to Chapter 23 of the 2016 Edition of the California ll Building Code to read as follows: 2305.4 Quality of Nails. In Seismic Design Category D. E or F, mechanically driven nails used in wood structural panel shear walls shall meet the same dimensions as that required for hand-driven nails, including diameter, minimum length and minimum head diameter. Clipped head or box nails are not permitted in new construction. The allowable design value for clipped head nails in existing construction may be taken at no more than the nail-head-area ratio of that of the same size hand-driven nails. RATIONALE: The overdriving of nails into the structural wood panel still remains a concern when pneumatic nail guns are used for wood structural panel shear wall nailing. Box nails were observed to cause massive and multiple failures of the typical 3/8-inch thick plywood during the 1994 Northridge Earthquake. The use of clipped head nails as allowed in Table Al of AFPA SDPWS footnote referencing to ASTM F1667, continues to be restricted from being used In wood structural panel shear walls where the minimum nail head size must be maintained in order to minimize nails from pulling through sheathing materials. Clipped or mechanically driven nails used in wood structural panel shear wall construction were found to perform much less in previous wood structural panel shear wall testing done at the University of California Irvine. The existing test results indicated that, under cyclic loading, the wood structural panel shear walls were less energy absorbent and less ductile. The panels reached ultimate load capacity and failed at substantially less lateral deflection than those using same size hand-driven nails. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require mechanically driven nails to have the same dimensions as hand-driven nail will result in improved quality of construction and performance of wood structural panel shear walls and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Code Page 42 of 118 2016 Edition of the California Residential Code Final Version:08105/2016 21316 Edition of the California Green Building Standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 23-04. Section 2305.5 is added to Chapter 23 of the 2016 Edition of the California Building Code to read as follows: 2305.5 Hold-down connectors. In Seismic Design Category D, E or F, hold-down connectors shall be designed to resist shear wall overturning moments using approved cyclic load values or 75 percent of the allowable seismic load values that do not consider cyclic loading of the product. Connector bolts into wood framing shall require steel plate washers on the post on the opposite side of the anchorage device. Plate size shall be a minimum of 0.229 Inch by 3 inches by 3 inches (5.82 mm by 76 mm by 76 mm) In size. Hold-down connectors shall be tightened to finger tight plus one half(112) wrench turn iust prior to covering the wall framing. RATIONALE: ICC-ES AC 155 Acceptance Criteria for Hold-downs (Tie-Downs) Attached to Wood Members is widely used to establish allowable values for hold-down connectors in evaluation reports. AC 155 uses monotonic loading to establish allowable values. Yet, cyclic and dynamic forces imparted on buildings and structures by seismic activity cause more damage than equivalent forces that are applied in a monotonic manner. However, the engineering, regulatory and manufacturing industries have not reached consensus on the appropriate cyclic or dynamic testing protocols, This condition is expected to continue for some time. In the interim, this proposed amendment continues to limit the allowable capacity to 75% of the evaluation report value to provide an additional factor of safety for statically tested anchorage devices. Steel plate washers will reduce the additional damage that can result when hold-down connectors are fastened to wood framing members. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles with additional editorial revisions for clarification.

The proposed modification to establish minimum performance requirements for hold-down connectors will reduce failure of wood structural panel shear walls due to excessive deflection and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Residential Building Code Page 0 40 of 2016 Edition of the California Geen Building Code Final Version:08105/2016 2016 Edition of the California Green evlldirg Standards Code updated Version:08Y23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP 23-05. Section 2306.2 of the 2016 Edition of the California Building Code is amended to read as follows: 2306.2 Wood-frame diaphragms. Wood-frame diaphragms shall be designed and constructed in accordance with AWC SDPWS. Where panels are fastened to framing members with staples, requirements and limitations of AWC SDPWS shall be met and the allowable shear values set forth in Table 2306.2(1) or 2306.2(2) shall only he permitted for structures assigned to Seismic Design Category A B, or C. Exception:Allowable shear values where panels are fastened to framing members with staples may be used if such values are substantiated by cyclic testing and approved by the building official. The allowable shear values in Tables 2306.2(1) and 2306.2(2) are permitted to be increased 40 percent for wind design. Wood structural panel diaphragms used to resist seismic forces in structures assigned to Seismic Design Category D, E or F shall be applied directly to the framing members. Exception: Wood structural panel diaphragms are permitted to be fastened over solid lumber planking or laminated decking, provided the panel ioints and lumber planking or laminated decking joints do not coincide. RATIONALE: The Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be "more thoroughly substantiated with testing.'The allowable shear values for wood structural panel shear walls or diaphragms fastened with staples are based on monotonic testing and does not take into consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with staples would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D, E and F unless it can be substantiated by cyclic testing. Furthermore, the cities and county within the Los Angeles region has taken extra measures to maintain the structural integrity of the framing of shear walls and diaphragms designed for high levels of seismic forces by requiring wood sheathing be applied directly over the framing members and prohibiting the use of panels placed over gypsum sheathing. This proposed amendment is intended to prevent the undesirable performance of nails when gypsum board softens due to cyclic earthquake displacements and the nail ultimately does not have any engagement in a solid material within the thickness of the gypsum board. i This proposed amendment continues the previous amendment adopted during the 2010 code adoption cycle.

Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non-structural concrete slab floors, wood floors, etc. The proposed change is to limit the use of the exception to structures assigned to Seismic Design Category A, B sr C where lower seismic demands are expected. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. 2016 Edition of the California Building Code Page 54 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:0&'2312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake.

Section 2308.6.9 of the 2016 Edition of the California Building Code is amended to read as follows: 2308.6.9 Attachment of sheathing. Fastening of braced wall panel sheathing shall not be less than that prescribed in Tables 2308.6,1 or 2304.10.1. Wall sheathing shall not be attached to framing members by adhesives. Staple fasteners in Table 2304.10.1 shall not be used to resist or transfer seismic forces in structures assigned to Seismic Design Category D, E or F. Exception:Staples may be used to resist or transfer seismic forces when the allowable shear values are substantiated by cyclic testing and approved by the building official. All braced wall panels shall extend to the roof sheathing and shall he attached to parallel roof rafters or blocking above with framing clips (18 gauge minimum) spaced at maximum 24 inches (6098 mm) on center with four 8d nails per leg (total eight 8d nails per clip). Braced wall panels shall be laterally braced at each top corner and at maximum 24 inches (6096 mm) intervals along the top plate of discontinuous vertical framing. RATIONALE: This proposed amendment is intended to improve the performance level of buildings and structures that are subject to the higher seismic demands placed on buildings or structure in this region. This proposed amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC)and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Conventional framing does not address the need for a continuous load path, critical shear transfer mechanisms, connection ties, irregular and flexible portions of complex shaped structures. The proposed modification to provide specific detailing requirements will improve the performance of buildings and structures and therefore needs to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the California Building Code. 2016 Edition of the California Building Code Page 56 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 i i I I 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM PART II LARUCP RECOMMENDED CODE AMENDMENTS TO THE 2016 EDITION OF THE CALIFORNIA RESIDENTIAL CODE 1 2016 Edition of the California Building Code Page 58 of 118 2016 Edition of the California Residential(ode Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 1 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM SUMMARY OF RECOMMENDED LARUCP AMENDMENTS TO THE 2016 CRC (N)2016.

Section R301.1.3.2 of the 2016 Edition of the California Residential Code is amended to read as follows: R301.1.3.2 Woodframe structures—greater—than-two-stories, The building official shall require construction documents to be approved and stamped by a California licensed architect or engineer for all dwellings of woodframe construction more than two stories and basement in height located in Seismic Design Category A B or C.Notwithstanding other sections of law;the law establishing these provisions is found in Business and Professions Code Section 5537 and 6737.1. The building official shall require construction documents to be approved and stamped by a California licensed architect or engineer for all dwellings of woodframe construction more than one story in height or with a basement located in Seismic Design Category Do Di. D,or E. RATIONALE: After the 1994 Northridge Earthquake, the Wood Frame Construction Joint Task Force recommended that the quality of wood frame construction need to be greatly improved. One such recommendation identified by the Task Force is to improve the quality and organization of structural plans prepared by the engineer or architect so that plan examiners, building inspectors,contractors and special inspectors may logically follow and construct the presentation of the seismic force-resisting systems in the construction documents. For buildings or structures located in Seismic Design Category D , Di, Do or E that are subject to a greater level of seismic forces, the requirement to have a California licensed architect or engineer prepare the construction documents is intended to minimize or reduce structural deficiencies that may cause excessive damage or injuries in wood frame buildings. Structural deficiencies such as plan and vertical irregularities, improper shear transfer of the seismic force-resisting system, missed details or connections important to the structural system, and the improper application of the prescriptive requirements of the California Residential Code can be readily addressed by a registered design professional. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northddge Earthquake. The proposed modification to require construction documents for wood frame construction greater than one story in height or with a basement to be approved and stamped by a California licensed architect or engineer is intended to assure that both the structural design and prescriptive requirement of the code are properly utilized and presented and therefore need to be incorporated into the code to assure that new buildings and structures, and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 Edition of the California Building Code Page 60 of 118 2018 Edition of the California Residential Code Final Version:OB/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R3-02. Section R301.1.4 is added to Chapter 3 of the 2016 Edition of the California Residential Code to read as follows: R301.1.4 Seismic design provisions for buildings constructed on or into slopes steeper than one unit vertical in three units horizontal 133.3 percent slope). The design and construction of new buildings and additions to existing buildings when constructed on or into slopes steeper than one unit vertical in three units horizontal (33.3 percent slope) shall comply with Section 1613.9 of the Building Code. RATIONALE: Due to the difficulty of fire suppression vehicles accessing winding and narrow hillside properties and the probabilities for future earthquakes in the Los Angeles region, this technical amendment is required to address the special needs for buildings constructed on hillside locations. A joint Structural Engineers Association of Southern California (SEAOSC) and both the Los Angeles County and Los Angeles City Task Force investigated the performance of hillside building failures after the Northridge earthquake. Numerous hillside failures resulted in loss of life and millions of dollars in damage. These criteria were developed to minimize the damage to these structures and have been in use by both the City and County of Los Angeles for several years with much success. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles. FINDINGS: Local Topographical and Geological Conditions—The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the topography within the Los Angeles region includes significant hillsides with narrow and winding access that makes timely response by fire suppression vehicles challenging and difficult. The proposed modification establishes design parameters to better mitigate and limit property damage that are the results of increased seismic forces which are imparted upon hillside buildings and structures and therefore need to be incorporated into the code to assure that new buildings and slmctures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code.

RATIONALE: Wth the higher seismic demand placed on buildings and structures in this region,.precautionary steps are proposed to reduce or eliminate potential problems that may result by limiting the type of irregular conditions specified in the California Residential Code. Such limitations are intended to reduce the potential structural damage expected in the event of an earthquake. The cities and county of the Los Angeles region has taken extra measures to maintain the structural integrity of the framing of the shear • walls and all associated elements when designed for high levels of seismic loads. • FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed amendment limits the type of irregular conditions within buildings that may lead to higher structural damage during a seismic event and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code and consistent with the requirements in the ASCE 7-10. 2016 Edition of the California Building Code Page 63 of 118 2016 Edition of the California Residential Code Final Version.OR10512016 2016 Edition of l0e California Green Building Standards Code Updated Version:08/2312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R3-04. Section R301.2.2.3.8 is added to Chapter 3 of the 2016 Edition of the California Residential Code to read as follows: R301.2.2.3.8 Anchorage of Mechanical. Electrical, or Plumbing Components and Equipment. Mechanical, electrical, or plumbing components and equipment shall be anchored to the structure. Anchorage of the components and equipment shall be designed to resist loads in accordance with the California Building Code and ASCE 7 except where the component is positively attached to the structure and flexible connections are provided between the component and associated ductwork, piping, and conduit;and either 1. The component weighs 400 lb(1.780 N) or less and has a center of mass located 4 ft(1.22 m) or less above the supporting structure:or 2. The component weighs 20 lb (B9N) or less or in the case of a distributed system, 5 lb/ft(73 N(m) or less. RATIONALE: There is no limitation for weight of mechanical and plumbing fixtures and equipment in the California Residential Code. Requirements from ASCE 7 and the California Building Code would permit equipment weighing up to 400 lbs.when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this proposed amendment that a registered design professional be required to analyze if the floor support is adequate and structurally sound. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to limit the equipment weight is intended to reduce injuries, save lives, and minimize structural damages and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 EtlWOn of the California Building Code Page 64 of 118 2016 Edition of the California Residential Code Final Version:08/05)2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM • 2016 LARUCP R4-01. Section R401.1 of the 2016 Edition of the California Residential Code is amended to read as follows: R401.1 Application. The provisions of this chapter shall control the design and construction of the foundation and foundation spaces for buildings. In addition to the provisions of this chapter, the design and construction of foundations in flood hazard areas as established by Table R301.2(1) shall meet the provisions of Section R322. Wood foundations shall be designed and installed in accordance with AWC PWF. Exception: The provisions of this chapter shall be permitted to be used for wood foundations only in the following situations: 1. In buildings that have no more than two floors and a roof. 2. When interior basement and foundation walls are constructed at intervals not exceeding 50 feet(15 240 mm). Wood foundations in Seismic Design Category D0, DI or D2 shall ho-designod in pocerdance-with leering-practise not be permitted. Exception: In non-occupied, single-story, detached storage sheds and similar uses other than carport or garage, provided the gross floor area does not exceed 200 square feet the plate height does not exceed 12 feet in height above the grade plane at any point and the maximum roof projection does not exceed 24 inches. RATIONALE: No substantiating data has been provided to show that wood foundation is effective in supporting buildings and structures during a seismic event while being subject to deterioration caused by the combined detrimental effect of constant moisture in the soil and wood-destroying organisms. Wood foundation, when they are not properly treated and protected against deterioration, have performed very poorly and have led to slope failures. Most contractors are typically accustomed to construction in dry and temperate weather in the Southern California region and are not generally familiar with the necessary precautions and treatment of wood that makes it suitable for both seismic event and wet applications.The proposed amendment takes the precautionary steps to reduce or eliminate potential problems that may result in using wood foundation that experience relatively rapid decay due to the fact that the region does not experience temperatures cold enough to destroy or retard the growth and proliferation of wood- destroying organisms. However, an exception is made for non-occupied, single-story storage structures that pose significantly less risk to human safety and may utilize the wood foundation guidelines specified in this Chapter. This proposed amendment is a continuation of an amendment adopted during previous code adoption cycles for the California Residential Code. FINDINGS: Local Climatic and Geological Conditions —The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. In addition, the region is within a climate system capable of producing major winds, fire and rain related disasters, including but not limited to those caused by the Santa Ana winds and El Nino (or La Nina) subtropical-like weather. This region is especially susceptible to more active termite and wood attacking insects and microorganisms.

Requiring minimum reinforcement for stepped footings is intended to address the problem of poor performance of plain or under-reinforced footings during a seismic event. Furthermore, interior walls can easily be called upon to resist over half of the seismic loading imposed on simple buildings or structures. Without a continuous foundation to support the braced wall line, seismic loads would be transferred through other elements such as non-structural concrete slab floors,wood floors, etc. The proposed change is to limit the use of the exception to structures assigned to Seismic Design Category A, B or C where lower seismic demands are expected. Requiring interior braced walls be supported by continuous foundations is intended to reduce or eliminate the poor performance of buildings or structures.This proposed amendment is consistent with an amendment adopted during previous code adoption cycles for the California Residential Code. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require continuous footings under braced wall lines, require reinforcement in one-and two- family dwelling, and minimum reinforcement in stepped footings will improve performance of buildings or structure during a seismic event and minimize potential problems or deficiencies and therefore need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the California Residential Code.

Requirements from ASCE 7 and the California Building Code would permit equipment weighing up to 400 lbs. when mounted at 4 feet or less above the floor or attic level without engineering design. Where equipment exceeds this requirement, it is the intent of this proposed amendment that a registered design professional is required to analyze if the floor support is adequate and structurally sound. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to limit the equipment weight is intended to reduce injuries, save lives, and minimize structural damages and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code.

RATIONALE: The Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the damages to buildings and structures during the 1994 Northridge Earthquake recommended reducing allowable shear values in wood structural panel shear walls or diaphragms that were not substantiated by cyclic testing. That recommendation was consistent with a report to the Governor from the Seismic Safety Commission of the State of California recommending that code requirements be"more thoroughly substantiated with testing:'The allowable shear values for wood structural panel shear walls or diaphragms fastened with staples are based on monotonic testing and does not take into consideration that earthquake forces load shear wall or diaphragm in a repeating and fully reversible manner. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened with staples would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category De, Ch and 02 unless it can be substantiated by cyclic testing.

In addition, shear walls sheathed with other materials are prohibited in Seismic Design Category Do, Dr and D2 to be consistent with the design limitation for similar shear walls found in the California Building Code. The poor performance of such shear walls in the 1994 Northridge Earthquake was investigated by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Task Force and formed the basis for this proposed amendment. Considering that shear walls sheathed with lath, plaster or gypsum board are less ductile than steel moment frames or wood structural panel shear walls, the cities and county of the Los Angeles region has taken the necessary measures to limit the potential structural damage that may be caused by the use of such walls at the lower level of multi-level building that are subject to higher levels of seismic loads. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to increase the length and limit the location where shear walls sheathed with lath, plaster or gypsum board are used will help to ensure that multi-level building will reach its performance objective in resisting higher levels of seismic loads and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code.

RATIONALE: 318" thick 3 ply-plywood shear walls experienced many failures during the Northridge Earthquake. Box nails were observed to cause massive and multiple failures of the typical 3/8"thick 3-ply plywood during the Northridge Earthquake. This proposed amendment specifies minimum sheathing thickness, nail size and spacing so as to provide a uniform standard of construction for designers and buildings to follow.This is intended to improve the performance level of buildings and structures that are subject to the higher seismic demands and reduce and limit potential damages to property. This proposed amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance observed in 1994 Northridge Earthquake. In September 2007, limited cyclic testing was conducted by a private engineering firm to determine if wood structural panels fastened wih staples would exhibit the same behavior as the wood structural panels fastened with common nails. The test result revealed that wood structural panel fastened with 2016 Edition of the California Building Code Page 0 0 118 2013 Edition of the California Residential en u Code Final Version:06r05/2016 2016 Edition of the California Green Building Standards Code Updated Version:Og1231201fi 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM staples appeared to be much lower in strength and stiffness than wood structural panels fastened with common nails. It was recommended that the use of staples as fasteners for wood structural panel shear walls or diaphragms not be permitted to resist seismic forces in structures assigned to Seismic Design Category D0, D, and D2 unless it can be substantiated by cyclic testing. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to place design and construction limits on stapled nail fasteners used in wood structural panel shear walls not substantiated with cyclic testing and requiring minimum sheathing thickness and nailing type and size will help to maintain minimum quality of construction and performance standards of structures and therefore need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 Edition at the California Building Code Page 81 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Verslan:0812312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R6.05.

FINDINGS: Local Geological Conditions — The greater Los Angeles region Is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to not allow the use of unreinforced masonry is intended to prevent non-ductile failures and sudden structural collapses and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 Edition of the California Building Code Page 91 of 118 2016 Edition oftne California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R6-11.

Vertical reinforcement. Vertical reinforcement shall consist of at least one No. 4 bar spaced not more than 48 inches (1219 mm). Vertical reinforcement shall be within 16 8 inches (406mm) of the ends of masonry walls. RATIONALE: Reinforcement using longitudinal wires for buildings and structures located in high seismic areas are deficient and not as ductile as deformed rebar. Having vertical reinforcement closer to the ends of masonry walls help to improve the seismic performance of masonry buildings and structures. This proposed amendment is a continuation of an amendment adapted during the previous code adoption cycle. FINDINGS: Local Geological Conditions - The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to increase reinforcements will ensure that the ductility requirements for buildings in high seismic region meet the intent of the code and limit potential property damages and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. ii 2016 Edition of the California Building Code Pane 92 of 118 2016 Edition of the California Residential Code Final Version:06/05/2016 2016 Edition of the California Green Building Standards Code Updated Version:08232016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R6-12.

The performance of modern day braced wall panel construction is directly related to an adequate load path extending from the roof diaphragm to the foundation system.A single top plate is likely to be over nailed due to the nailing requirements at a rafter, stud, top plate splice, and braced wall panel edge in a single location. In addition, notching on a single top plate for plumbing, ventilation and electrical wiring may reduce the load transfer capacity of the plate without proper detailing. Majority of buildings and structures designed and built per the California Residential Code with a single top plate may not need structural observation and special inspections. The potential construction mistakes mentioned above could not be caught and corrected by knowledgeable engineers and inspectors, and could jeopardize structural performance of buildings and structures located in high seismic areas. This proposed amendment is a continuation of an amendment adopted during the previous code adoption cycle. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to eliminate the usage of a single top plate will help to maintain minimum quality of construction and performance standards of structures and therefore need to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed In accordance with the scope and objectives of the California Residential Code. 2016 Edition of the California Building Code Page 93 of 118 2016 Edition of the California Residential Code Final Version:08/05/2016 2018 Edition of the California Green Building Standards Code Updated Version:08)2312016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R8-01. Section R803.2.4 is added to Chapter 8 of the 2016 Edition of the California Residential Code to read as follows: R803.2.4 Openings in horizontal diaphragms. Openings in horizontal diaphragms shall conform with Section R503.2.4. RATIONALE: Section R802 cf the Code does not provide any prescriptive criteria to limit the maximum roof opening size nor does Section R803 provide any details to address the issue of shear transfer near larger roof openings.With the higher seismic demand placed on buildings and structures in this region, it is important to ensure that a complete load path is provided to reduce or eliminate potential damages caused by seismic forces. Requiring blocking with metal ties around larger roof openings and limiting opening size is consistent with the requirements of Section R301.2.2.2.5. • FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to require specific detailing at large roof openings Is intended to address the poor perfomiance of roof diaphragms with openings and limit or reduce property damages during a seismic event and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 Edition of the California Building Code Page 94 of 115 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building Standards Coda Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM 2016 LARUCP R10-01. Section R1001.3.1 of the 2016 Edition of the California Residential Code is amended to read as follows: R1001.3.1 Vertical reinforcing. For chimneys up to 40 Inches (1016 mm) wide, four No. 4 continuous vertical bars adequately anchored into the concrete foundation shall be placed between wythes of solid masonry or within the cells of hollow unit masonry and grouted in accordance with Section R609. Grout shall be prevented from banding with the flue liner so that the flue liner is free to move with thermal expansion. For chimneys more than 40 inches (1016 mm) wide, two additional No. 4 vertical bars adequately anchored Into the concrete foundation shall be provided for each additional flue incorporated into the chimney or for each additional 40 inches(1016 mm) in width or fraction thereof. RATIONALE: The performance of fireplace/chimney without anchorage to the foundation has been observed to be inadequate during major earthquakes. The lack of anchorage to the foundation can result in the overturning or displacement of the fireplace/chimney. FINDINGS: Local Geological Conditions — The greater Los Angeles region is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. The proposed modification to anchor masonry chimneys into concrete foundation will reduce injuries, save lives, and minimize structural damages and therefore needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Residential Code. 2016 Edition of the California Building Code Page 95 of 116 2016 Edition of the California Residential Code Final Version:08/05/2016 2016 Edition of the California Green Building standards Code Updated Version:08/23/2016 2016 EDITION OF THE LOS ANGELES REGION UNIFORM CODE PROGRAM PART III LARUCP RECOMMENDED CODE AMENDMENTS TO THE 2016 EDITION OF THE CALIFORNIA GREEN BUILDING STANDARDS CODE (MANDATORY REQUIREMENTS) 2016 Edition of the California Building Code Page 5e of 118 2016 Edition ofiM1e Cafdomia Residential Code Final Version:0810512016 2016 Edition of the California Green Building Slandards Code Updated Version:013/232016 2016 ELES REGION UNIFORM CODE PROGRAM SUMMARY OF RECOMMENDED LARUCP AMENDMENTS TO THE 2016 CALGREEN (N)2016 (E)2013 LARUCP LARUCP TITLE/DESCRIPTION STATUS _ NO.

Section 301.1.1 of the 2016 Edition of the California Green Building Standards Code is amended to read as follows: Section 301.1.1 Additions and alterations. [HCD) The mandatory provisions of Chapter 4 shall be applied to additions or alterations of existing residential buildings- - --- e - - -•. ••• . . -. dtien ar-alterptee. Code sections relevant to additions and alterations shall only apply to the portions of the building being added or altered within the scope of the permitted work. Note: On and after January 1, 2014, residential buildings undergoing permitted alterations,additions or improvements shall replace noncompliant plumbing fixtures with water-conserving plumbing fixtures. Plumbing fixture replacement is required prior to issuance of a certificate of final completion, certificate of occupancy or final permit approval by the local building department. See Civil Code Section 1101.1, et seq., for the definition of a noncompliant plumbing fixture, types of residential buildings affected and other important enactment dates. RATIONALE: This proposed amendment simplifies the language and increase the scope of application that requires the CALGreen Code to be applied to all residential projects. This section, as written, can only be applied to an existing dwelling if the volume or size of the condition space is increased and does not encompass interior remodels. This proposed amendment modifies the State language to require additions, alterations, and interior remodels to comply with applicable sections of the CALGreen Code that are relevant to the scope of work. Studies have shown that new dwellings built equal to less than 10% of the total housing stock in the State. Although new dwellings have complied with the CALGreen Code, the larger challenge is with existing dwellings. The bulk of California's energy is generated by aging power plants. Increasingly, the development and application of alternate energy methods such as photovoltaics has gained market adoption. Coupling these new energy generation processes with energy saving measures in the California Energy Code will allow jurisdictions, states or the federal government to potentially offset the need to construct new power plants.which would equate to a savings of billions of tax-payer dollars. Water conservation is addressed by the CALGreen Code by implementing more restrictive requirements for landscape irrigation and plumbing fixtures. Indoor air quality is addressed by the CALGreen Code by implementing multiple limits for VOC (volatile organic compounds) in paints, sealants and construction adhesives and formaldehyde contents In composite wood products. These new standards that restricts VOC and formaldehyde contents have shown to improve indoor air quality and minimize or eliminate occupant health issues related to sick building syndrome. FINDINGS: Local Environmental Condition — This amendment is necessary on the basis of a local environmental condition. The majority of the building stocks in the greater Los Angeles region are existing dwellings.To reduce the impact that the existing dwelling is having on energy, water, and air quality, this amendment proposes to address compliance with the CALGreen Code at the time when a permit is issued. Existing buildings have been estimated to account for up to 40% of greenhouse gas emissions. This amendment offset this impact on the communities by implementing more restrictive measures in the CALGreen Code, whenever possible. Any residential projects that require a permit to be Issued will be required to comply with only those sections that are relevant to the scope of work and thereby begin to contribute to 2016 Edition of Oe California Building Code Page 102 of 118 2016 Edition of the California Residential Coda Final Version:08105/2016 2016 Edition of the California Green Building Standards Code Updated Version:08/2312016 2016 EDITION OF THE LOS N UNIFORM CODE PROGRAM improving the environment.

Research has shown that the greater Los Angeles region suffers from heat island with the temperature having increased as the region became more urban.The higher temperatures are closely related to air pollution. Additionally, raising temperatures increase the overall and peak energy consumption for cooling creating additional air pollution from the increased power production. FINDINGS: Local Environmental Condition — This amendment is necessary on the basis of a local environmental condition.The greater Los Angeles region[OR NAME OF CITY OR REGION]is a densely populated area where a majority of the building stocks are existing residential buildings. Existing dwellings have been estimated to account for up to 40% of greenhouse gas emissions. This amendment offset this impact an the communities by requiring addition or alteration to existing dwellings to comply with the CALGreen Code.Any dwellings that require a permit to be issued will be required to comply with only those sections that are relevant to the scope of work and thereby begin to contribute to improving the environment.
