Local Amendments to Building Standards - Ordinances

Appeals Information

California Building Standards Code (California Code of Regulations, Title 24)

The California Building Standards Code is a compilation of three types of building standards 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 national model codes to address California’s ever-changing conditions; and
  • Building standards, authorized by the California legislature, that constitute amendments not covered by national model codes, that have been created and adopted to address particular California concerns.

All occupancies in California are subject to national model codes adopted into Title 24, and occupancies are further subject to amendments adopted by state agencies and ordinances implemented by local jurisdictions’ governing bodies.
