Contractors State License Board of California

The Contractors State License Board was established in 1929 at the request of the building industry to protect consumers. Today, the Board continues to protect consumers before and after they hire building contractors. A fifteen-member board appoints the CSLB executive officer, or Registrar, and directs administrative policy for the 450 Board staff members who work from a headquarters office in Sacramento and field offices throughout the state. The board includes nine public members, five contractors, and one labor representative.

The CSLB licenses and regulates contractors in 42 license classifications, investigates complaints against contractors, and through SWIFT (Statewide Investigative Fraud Team), works to eliminate the number of unlicensed contractors working in California.

It provides free publications about hiring contractors and the construction process and maintains this informational web site and toll-free automated telephone response system that provide the public with contractor licensing information.
