Welcome to the Contractors State License Board

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.

Home Improvement Payment Reminder

Contractors installing residential solar, constructing accessory dwelling units (ADUs), performing home improvement work, or rebuilding homes in declared disaster areas (including new home rebuilding) may not request or receive a down payment of more than $1,000.

Following the down payment, progress payments can only be for work completed or materials provided. IT IS AGAINST THE LAW FOR A HOME IMPROVEMENT CONTRACTOR TO COLLECT PAYMENT FOR WORK NOT YET COMPLETED OR FOR MATERIALS NOT YET DELIVERED.
