Norwalk council introduces 2025 California building standards ordinance for first reading

The City of Norwalk introduced for first reading ordinance number 25-1761, which proposes to adopt by reference the 2025 edition of the California Building Standards Codes (including building, residential, plumbing, electrical, mechanical, energy, fire, wildland-urban interface and related parts) with local amendments designed to reflect Norwalk’s conditions.

Building official Faye Yuan explained that the California Building Standards Commission published the 2025 code cycle and that state law requires cities begin enforcing the new cycle on Jan. 1, 2026 unless local amendments are adopted. Yuan listed notable state-level changes in the 2025 codes — for example, new wildfire interface provisions, updated requirements for battery-storage systems, changes to window U-factors and solar/battery readiness requirements — and described the city’s limited authority to adopt amendments where local climatic, topographic or geologic conditions justify stricter rules. “All cities must begin enforcing these new codes with or without local amendments starting 01/01/2026,” Yuan said (01:01:50).

Staff recommended that council introduce the ordinance by title only and set a public hearing and adoption for Nov. 18, 2025. Council moved, seconded and voted aye on the motion to introduce ordinance 25-1761 for first reading.

Yuan also said the Los Angeles County Fire Department is preparing county-level amendments; because the city contracts with LA County for fire plan checks and inspections, Norwalk will coordinate adoption of the county’s fire code changes once the county completes its process. Notices and informational materials will be available at the city’s permit counter and on the city website to help applicants prepare for the January 2026 enforcement date.

No public speakers commented on the item that evening.
