California Construction Code and Edition Adopted:

California is on a three-year code cycle as well. Local jurisdictions are required to enforce the Code as adopted but are allowed to request approval from the CBSC based on local geographic, climactic, or geologic conditions.

Applicability (statewide, local, limited): STATEWIDE

Title 24 serves as the basis for the design and construction of buildings in California. Codes are adopted at the state level and are enforced on a statewide basis. Each local building and fire jurisdiction may amend these state codes providing their amendments are more stringent based on findings justified by climatic, geographic and topographical conditions of the jurisdiction. California’s  codes are published in their entirety every three years. Intervening Code Adoption Cycles produce Supplement pages half-way (18 months) into each triennial period. Amendments to California’s building standards are subject to a lengthy and transparent public participation process throughout each code adoption cycle. The 2019 California Building Code is based on the 2018 edition of the I-Codes.
