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 is the building code for California, and Title 24 of the California Code of Regulations (CCR). It is maintained by the California Building Standards Commission which is granted the authority to oversee processes related to the California building codes by California Building Standards Law. The California building codes under Title 24 are established based on several criteria: standards adopted by states based on national model codes, national model codes adapted to meet California conditions, and standards passed by the California legislature that address concerns specific to California.
Portions of editions of the California building codes are published by the International Code Council (ICC), International Association of Plumbing and Mechanical Officials (IAPMO), and BNi Building News. As they are, in effect, amended versions of copyright works such as the International Building Code (IBC) maintained by the International Code Council (ICC), the regulations have substantial portions under copyright, and hence may be withheld from the public or individuals, but still have the force of law. In 2008, Carl Malamud published the California Building Standards Code on Public.Resource.Org for free.
California’s building codes are published in their entirety every three (3) 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 adoption cycle.
