Effective January 1, 2026, the 2025 CA Building Standards Code (California Code of Regulations, Title 24) as shown below will become effective on a statewide basis. For more information, please go to The California Building Standards Commission.
California Code of Regulations, Title 24
The 2025 Codes apply to all building projects with an application date of January 1, 2026, or later. However, if your project or application was initiated before this date, the previous 2022 Codes will still apply during construction inspections and the plan check process. It is essential to keep your permit up to date and demonstrate ongoing progress on your project. Permits are valid for two years from the date of issuance and can be renewed for an additional year. Reactivating an expired permit will require a review to ensure compliance with the new codes, based on the status of the construction.
