Welcome to the California Building Standards Commission

CBSC is authorized by California Building Standards Law to administer the many processes related to the development, adoption, approval, publication, and implementation of California’s building codes. 

The California Building Standards Code, Title 24 serves as the basis for the design and construction of buildings in California. Improved safety, sustainability, maintaining consistency, new technology and construction methods, and reliability are paramount to the development of building codes during each Triennial and Intervening Code Adoption Cycle

California’s building 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.
