Codes

California Code of Regulations (CCR), Title 24, also known as the California Building Standards Code, is a compilation of three types of building criteria from three different origins:

  • Building standards that have been adopted by state agencies without change from building standards contained in national model codes;
  • Building standards that have been adopted and adapted from the national model code standards to meet California conditions; and
  • Building standards, authorized by the California legislature, that constitute extensive additions not covered by the model codes that have been adopted to address particular California concerns

Notwithstanding, the national model code standards adopted into Title 24 apply to all occupancies in California except for modifications adopted by state agencies and local governing bodies. To learn more go to Guide to Title 24.

Starting in 1989, the BSC has published triennial editions of Title 24 in their entirety every three years. Title 24 is available for purchase or to the public at no cost through depository libraries. The following triennial editions have been published in their entirety:
