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.
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.
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.
SEARCH TIPS A California contractor license number doesn't contain alphabetic characters. Each contractor's plastic pocket license will show the respective license number. Begin entry of your license number at the left position and don't exceed 8 digits in the license number.
This process was created by CSLB to allow insurers to fill in and submit Workers' Compensation policy requirements through the CSLB Website, directly into the database.
CSLB shall waive the renewal fees for a license that will expire during the time a licensee or registrant is called to active duty as a member of the United States Armed Forces or the California National Guard if certain requirements are met.
