California Residential Code (CRC) contains building provisions that cover construction of one- and two-family dwellings and townhouses that are three stories or less.

This is a fully integrated code based on the Building Provisions of the 2012 International Residential Code® (Chapters 2-10).

California amendments provide consistency with model code format, state and federal laws and regulations, and unique California conditions with regard to the construction of one- and two-family dwellings and townhouses.
This code does not include Energy, Mechanical, Plumbing or Electrical standards, which are found in other parts of Title 24.
