How to Verify a Painting Contractor's License in California

In California, hiring an unlicensed contractor for a sizable job can leave you with no recourse if the work goes wrong. The good news: the state makes it easy to check a painter's credentials yourself, for free. Here's the step-by-step.

Step 1: Search the CSLB license

The Contractors State License Board (CSLB) regulates contractors in California. Go to cslb.ca.gov and use "Check a License." You can search by:

• License number (ask the contractor for it), or
• Business name, or
• Personnel name

Painting contractors typically hold a "C-33" painting and decorating classification, though some carry a broader "B" general license.

Step 2: Confirm the license is active and in good standing

On the result page, check that the license status reads "Active." Avoid licenses that show as expired, suspended, or revoked. Also confirm the classification covers painting (C-33 or B).

Step 3: Check the bond

Licensed contractors are required to carry a contractor's bond. The CSLB page shows whether the bond is current. A bond offers you limited financial protection if the contractor fails to meet certain obligations.

Step 4: Check workers' compensation

If the contractor has employees, they must carry workers' compensation insurance — this protects you if a worker is injured on your property. The CSLB page shows their workers' comp status or an exemption (a sole proprietor with no employees may be exempt).

Step 5: Ask for proof of general liability insurance

General liability isn't shown on CSLB, so ask the contractor directly for a certificate of insurance. This covers damage to your property. A professional will provide it without hesitation.

Step 6: Watch for these red flags

• Refuses or "can't find" their license number
• License is expired, suspended, or for a different trade
• Wants a large cash deposit up front (California limits down payments on home-improvement contracts)
• No written contract or estimate
• Name on the license doesn't match who you're dealing with

Do painters always need a license in California?
