California C-33 Painting Contractor License: Scope, Verification, and Lead-Safe (RRP) Rules

The C-33 classification covers preparing surfaces and applying paint, coatings, wallcovering, and protective finishes — including the waterproofing that goes with painting and decorating — on interior and exterior surfaces.

It's a single-trade specialty, which is why much of the search noise around 'do painters need a license' is exam-prep content for people getting the C-33, not guidance for homeowners hiring one.

Any project where combined labor and materials total $1,000 or more must be performed by a CSLB-licensed contractor — the threshold rose from $500 to $1,000 on January 1, 2025 under Assembly Bill 2622 (Business & Professions Code §7048). Below $1,000, a narrow minor-work exemption can apply only if the job isn't part of a larger project and the worker discloses, in advertising and bids, that they aren't licensed.

A small touch-up under $1,000 in combined labor and materials can be done unlicensed, with disclosure. A whole-house repaint is well over the threshold and should go to an Active C-33.

Here's the differentiator the licensing-school pages skip: if your home was built before 1978, paint disturbance can release lead dust, and the contractor should hold EPA Lead Renovation, Repair and Painting (RRP) certification and follow lead-safe work practices. This is a separate federal credential — the CSLB record does not track it.

For a pre-1978 home, ask the painter for their EPA RRP certification in addition to the C-33. It protects your household during prep and sanding.

Confirm the license is Active and the C-33 classification is listed — on the CSLB "Check a License" tool or on the contractor's profile in this directory. Match the license to the business you're hiring. Check that the $25,000 contractor bond is on file (Business & Professions Code §7071.6) and that workers' compensation coverage — or a valid exemption — is shown.

On older homes, pair the CSLB check with a request for EPA RRP certification. Browse Active C-33 painters by city in the California painting directory and see each one's dated CSLB status before you hire.

A painting contractor must carry workers' compensation insurance for any employees. A contractor that genuinely works alone can currently file a no-employee exemption, so the CSLB record may show an exemption rather than a policy — confirm one or the other before you hire.

Senate Bill 1455 will extend that requirement to every CSLB licensee — regardless of employees — on January 1, 2028, with CSLB's exemption-verification process live by January 1, 2027. Five high-risk classifications already carry no exemption at all — C-8 (concrete), C-20 (HVAC), C-22 (asbestos abatement), C-39 (roofing), and D-49 (tree service) — and must hold coverage regardless of employees.
