Licensed Painter in California: How to Verify Before You Hire

California is one of the few states that requires painters to hold a specific license classification before performing painting work valued at $500 or more. Painters in California must hold a CSLB Class C-33 Painting and Decorating Contractor license issued by the Contractors State License Board. This makes California an outlier compared to most states where painters are not separately licensed — and it means California homeowners have a clear, searchable credential to verify before hiring.

The CSLB C-33 license covers painting, decorating, wallpapering, sandblasting, and surface preparation work on residential and commercial structures. Understanding what this license covers — and what happens when a painter tries to work without one — is essential before hiring for any California painting project.

Does California require painters to have a license?

Yes. California requires all contractors, including painting contractors, to hold a valid CSLB license for any work valued at $500 or more in combined labor and materials. For painting specifically, the required classification is Class C-33 Painting and Decorating Contractor. A painter who quotes you $501 or more and does not hold a C-33 license is performing unlicensed work in violation of California law.

• CSLB C-33 license required for painting work valued at $500 or more in California
• Covers painting, decorating, wallcovering, sandblasting, and surface preparation
• License required for both residential and commercial painting projects
• No separate city-level painting license exists in California — CSLB is the only authority
• Free verification at cslb.ca.gov using name or license number

How do I verify a California painter's C-33 license?

The CSLB at cslb.ca.gov provides a free license lookup where you can search any painter by name, business name, or license number. Results show the license classification (confirm it shows “C-33”), active status, expiration date, bond and workers' compensation status, and any disciplinary history. Confirm the license is currently active before signing any contract. An expired or suspended C-33 means the painter cannot legally work in California.

• CSLB license check: cslb.ca.gov — click “Check a License”
• Search by business name, individual name, or license number
• Confirm the license shows classification “C-33”
• Confirm status is “Active” and expiration date is current
• Confirm bond and workers' comp both show “Yes”

What does the C-33 license cover and what does it not cover?

The CSLB C-33 Painting and Decorating Contractor classification covers painting walls, ceilings, and surfaces; applying wallpaper and wall coverings; surface preparation including pressure washing and sanding; and decorating including staining and varnishing. It does not authorize the painter to perform structural work, install drywall (that is a C-9 classification), or perform any electrical or plumbing work. A painter who also does drywall repair must hold a separate C-9 license or work with a Class B general contractor.

• C-33 covers: painting, decorating, wallpaper, sandblasting, surface prep, staining, varnishing
• C-33 does not cover: drywall installation (requires C-9)
• C-33 does not cover: structural, electrical, or plumbing work
• If a painter will also repair drywall, ask for their C-9 license or confirm a general contractor is overseeing
• A painter performing work outside their C-33 scope is operating in violation of CSLB rules

What are the consequences of hiring an unlicensed painter in California?

California Business and Professions Code Section 7028 makes performing contractor work — including painting — without a CSLB license a criminal misdemeanor with fines up to $5,000 and potential jail time. The CSLB's SWIFT enforcement team conducts stings targeting unlicensed painters and contractors in California. For homeowners, hiring an unlicensed painter means no CSLB complaint process, no bond protection, and potential personal liability for workers' compensation if the painter is injured without their own insurance.

• Unlicensed painting work in California: misdemeanor, fines up to $5,000
• CSLB SWIFT team targets unlicensed painters throughout California
• California courts can prevent unlicensed contractors from collecting payment
• Homeowner faces workers' comp liability for uninsured unlicensed painters
• No CSLB complaint process for disputes with unlicensed painters

What else should I check when hiring a California painter?

The CSLB C-33 license check confirms the painter meets California's minimum requirements, but it does not tell you everything. Request a current certificate of general liability insurance to protect against damage to your property. Confirm workers' compensation coverage if the painting crew includes employees. Ask for references from comparable projects — a painter who regularly does interior residential work may not be experienced in commercial exteriors or specialty coatings.

• Request a certificate of general liability insurance naming you as additional insured
• Confirm workers' compensation coverage for any painting crew employees
• Ask for three references from similar painting projects in the past 12 months
• Request a written scope of work detailing preparation, number of coats, and materials
• Confirm what surface prep is included — this determines the quality of the final result
