How to check a California contractor license

Before hiring, compare the business information on a proposal with the California Contractors State License Board record. Ask the contractor to explain any questions about the record or coverage.

What you'll learn

  • The license lookup and business identity
  • Status and classification information
  • Insurance and workers compensation questions

Step by step

  1. Collect the details

    Ask the contractor for the business name and license number appearing on the proposal.

  2. Use the CSLB lookup

    Visit cslb.ca.gov and search for the contractor. Compare the result with the name and number provided.

  3. Read the record

    Review the status, classification, and any other information shown. Contact CSLB if you do not understand an entry.

  4. Discuss coverage

    Ask for insurance details and confirm the coverage with the insurer. Review workers compensation information on the CSLB record and ask about any exemption.

  5. Compare the written scope

    Ask for a written description of the work, payment terms, and who will handle permits and subcontractors.

Safety note

A license lookup is one part of hiring. Ask questions and check current information before signing.
