The new California Building Code update cycle is here! These new codes will be effective January 1, 2026.

The State of California operates on a triennial (three-year) code adoption cycle. The current 2022 California Building Standards Code will be superseded by the new 2025 California Building Standards Code (California Code of Regulations, Title 24)

Submittal Deadlines and Transition Policy

The governing code for a project is determined by the date a complete permit application is submitted to our department. This is a critical deadline for all pending and future projects. Due to the City Hall Holiday Closure schedule, we will be strictly following the timeline below for submittal deadlines:

Applications Submitted BEFORE December 24th, 2025:

Permit applications for new construction, additions, or alterations that are formally submitted and accepted as complete by our office on or before December 23rd, 2025, will be reviewed and inspected under the 2022 California Building Standards Code.

Applications Submitted ON OR AFTER December 24th, 2025:

All permit applications submitted on or after December 24th, 2025, must be designed and demonstrate full compliance with the 2025 California Building Standards Code. There will be no exceptions.

The code in effect at the time a permit application is submitted is the code that applies to that project throughout its duration
