CC - Item 4E - Introduction and First Reading of Ordinance No. 1030 Amending Title 15 to Adopt by Reference Title 24 of the 2025 California Building Standards CodeROSEMEAD CITY COUNCIL STAFF REPORT TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: BEN KIM, CITY MANAGER DATE: OCTOBER 14, 2025 SUBJECT: INTRODUCTION AND FIRST READING OF ORDINANCE NO. 1030 AMENDING TITLE 15 TO ADOPT BY REFERENCE TITLE 24 OF THE 2025 CALIFORNIA BUILDING STANDARDS CODE SUMMARY Every three (3) years, the State of California Building Standards Commission (CBSC) publishes revised Building Standards Code (Title 24, Parts 1 through 12), effective statewide beginning January 1ST of the code cycle. Whether or not the City takes formal adoption action, the City is required by law to enforce these provisions. Ordinance No. 1030 proposes the adoption of State codes directly. The CBSC continually monitors and revises the California Building Standards through a process of review which involves input from local chapters of the International Code Council (ICC), the California Association of Building Officials (CALBO), professional design associations, trade groups, and the general public. Every three (3) years the Building Standards Commission compiles these observations into a revised tri-annual version of the California Building Standards which are incorporated into the California Code of Regulations, Title 24, Parts 1 through 12. The most recent revisions were published on July 1, 2025 and mandated to become effective and enforceable by all California jurisdictions on January 1, 2026. Historically, the City has adopted the California Building Standards Code as amended by Los Angeles County. For the 2025 cycle, staff recommends adopting the California Building Standards Code directly as published by the State, with limited local amendments specific to Rosemead. Adopting the 2025 California Building Codes including the California Energy Code and California Historical Buildings Code would effectively serve to communicate the design and construction requirements on projects throughout the City of Rosemead. In addition, Contractors and Design Professionals would benefit from a consistent regional application of the codes. The CBSC continually refines Title 24 to address seismic safety, energy efficiency, fire safety, and green building standards. Adoption of State codes balances safety with cost-effectiveness also avoiding unnecessary restrictive provisions supports the City's strategic goals of encouraging housing AGENDA ITEM 4.E City Council Meeting October 14, 2025 Page 2 of 3 production, supporting small businesses, and maintaining a business -friendly regulatory environment. Local jurisdictions are enabled per California Building Code Section 1.1.8, to make amendments to the California Codes based on local geographic, topographic, climatic, and environmental conditions. However, the process to make these local amendments requires express findings to be made on each issue, and for those findings to be filed and approved by the State prior to becoming effective at the local level. The revisions to Title 15 of the Rosemead Municipal Code that are herein recommended include: • Adopting the 2025 editions of the California Building Standards Codes with less local amendments carried forward from the prior cycle. Adding Chapter 15.02 — Administration of Building Codes to the Municipal Code. Based on administrative needs identified in prior years, this would consolidate local provisions for permit expirations, extensions, refunds, valuation, and certificates. Chapter 15.02 supplements the administrative provisions of the California Building Code, Chapter 1, Division II, without altering the technical requirements of the State codes. STAFF RECOMMENDATION That the City Council: Move to INTRODUCE for FIRST READING, by title only, Ordinance No. 1030 (Attachment "A"), an ordinance of the City Council of the City of Rosemead adopting by reference, pursuant to Government Code Section 50022.2, the 2025 California Building Standards Code, including the California Building Code, the California Electrical Code, the California Plumbing Code, the California Mechanical Code, the California Residential Code, the California Green Building Code, the California Existing Buildings Code, the California Energy Code, and the California Historical Buildings Code, with certain amendments, additions, and deletions thereto. 2.

APPROVED AS TO FORM: Rachel Richman, City Attorney Attachment A: Local Amendment Findings Margaret Clark, Mayor ATTEST: Ericka Hernandez, City Clerk 16 ATTACHMENT"A" 2025 LOCAL AMENDMENT FINDINGS I. Geological Conditions 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 wood frame 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, D2, 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. 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 the improper application of the prescriptive requirements of the California Residential Code.
