Guide to Changes in State Law

As California’s 2025–2026 Legislative Session comes to a close, CALBO’s Legislative Team is tracking newly signed legislation that may impact building departments and local jurisdictions throughout the state.

To help CALBO members prepare for changes in state law, the Legislative Team publishes the guides to changes in state law, featuring summaries of significant legislation and what these new requirements may mean for building departments on the ground.

The guides provide practical information on key legislation to help local jurisdictions understand new requirements and prepare for implementation. Updated guides reflecting the 2025–2026 Legislative Session will be available later this year.

CALBO also publishes Selected State Laws Enforced by Building Departments, a comprehensive reference designed specifically for California building department professionals. The publication brings together state laws that building departments are responsible for enforcing, with a focus on the Health and Safety Code, Government Code, Business and Professions Code and other applicable California codes.

An updated edition of Selected State Laws Enforced by Building Departments will be available in 2027. 

The Guide to Changes in State Law and Selected State Laws Enforced by Building Departments are intended as informational resources and do not constitute legal advice. CALBO strongly encourages local jurisdictions to consult with their city or county attorneys regarding specific legal questions or the implementation of state laws.
