California
State AdoptionsCalifornia adopts its building codes through a structured, statewide process led by the California Building Standards Commission (CBSC). Every three years, the CBSC updates the California Building Standards Code (Title 24) based on national model codes—such as those from the International Code Council (ICC)—and coordinates with state agencies like the Division of the State Architect, Housing and Community Development, Cal Fire, and the Energy Commission to add California-specific amendments for seismic safety, accessibility, energy efficiency, and environmental protection. After public review and approval, the updated Title 24 becomes law statewide, while local jurisdictions may adopt stricter amendments to address regional needs such as seismic or climatic conditions.
