2022 Code Updates
The California Building Standards Commission (hereinafter the “Building Standards Commission”) is an independent commission within the State Business, Consumer Services and Housing Agency responsible for reviewing, adopting, and publishing building standards for the State of California. The Building Standards Commission adopts a compilation of updated building regulations every three years. These Codes include the:
- California Fire Code
- California Building Code
- California Residential Code
- California Electrical Code
- California Mechanical Code
- California Plumbing Code
- California Energy Code
- California Existing Building Code
- California Referenced Standards Code
- California Green Building Standards Code
The State of California Title 24 construction codes are typically updated and published on a three- year cycle. The International Code Council publishes the base codes in 2021, titled the 2021 International Building Code, the 2021 International Residential Code, etc. Then the various California regulatory agencies such as: the State Fire Marshal’s office; the Office of Statewide Health Planning and Development (OSHPD); the Division of the State Architect (DSA); and the California Department of Housing and Community Development (HCD) review and amend these base codes and republish them as the California Building Codes, Parts 1 through 12. The Building Standards Commission then publishes these triennial code updates, typically on July 1st, and State law mandates that these codes become effective throughout California 180 days after that publication date.
For this latest cycle, the publication date was July 1, 2022, meaning that the current cycle of State construction codes take effect on January 1, 2023. This is done in order to foster uniformity in fire prevention, life/safety, and construction standards statewide. Local jurisdictions are permitted to use that ensuing 180 days after publication to review and amend the California published codes based on local climatic, geological, or topographical conditions.
The 2022 Codes became effective on January 1, 2023 and apply to any project submitted for plan check thereafter. On November 15, 2022, the Los Angeles County Board of Supervisors (BOS) adopted the necessary Ordinances to adopt by reference the 2022 California Building, Electrical, Plumbing, Mechanical, Residential, Green Building Standards, and Existing Building Codes, with amendments.
