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 2015 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. Effective Date: January 1, 2017
