Every 3 years, the State of California adopts the most recent national building codes. The State also mandates that all California cities and counties adopt and begin enforcing those State codes on a specified date. According to the California Building Standards Commission, the 2013 California Building Codes (also known as Title 24) must be adopted and enforced beginning on January 1, 2014. Any projects submitted for first plan review on or after January 1, 2014 will be required to comply with the new codes. Projects submitted before that date will be allowed to remain under the previous editions of the codes for both plan review and inspections.
