The CSLB policies promote the health, safety and general welfare of the public in matters relating to construction. Their website contains extensive information for both the consumer and the contractor and may be found here. In California, anyone who contracts to perform work on a project for $500 or more for labor and materials must maintain a current, valid license from the CSLB. You can verify the license on-line by license number or by contractor name. If you do not have access to a computer you may call 1-800-321-CSLB (2752). Note that in California, a contractor license number does not contain alphabetic (a-z) characters and will not be more than 8 digits. A cautious statement from CSLB states: REMEMBER Most licensed contractors maintain competent, honest and hardworking business practices that are financially responsible. Most of the problems the California Contractors State License Board encounters could be prevented by homeowners knowing their home improvement rights and by the homeowner taking responsibility for their particular project. A responsible, informed consumer works more effectively with the contractor, therefore avoiding becoming a victim of unscrupulous or unlicensed practices.
