The Contractors State License Board (CSLB) protects California consumers by licensing and regulating the state's construction industry. CSLB was established in 1929 and today licenses about 285,000 contractors in 45 different classifications.
The Contractors State License Board (CSLB) follows a long history of consumer protection and licensing in California. Consumer protection began in 1876 when California passed the Medical Practice Act which would use licensing to combat completely unregulated medical practice.
CSLB addresses violations of California Contractors License Law, whether the contractor is licensed or unlicensed, for up to four years from the date of the act.
CSLB offers resources and information to help contractors perform professionally, legally, and safely. CSLB encourages licenses to routinely monitor their license status to confirm that it is "active" and not under suspension.
