Step 2: Verify licensing (don’t skip this)

In California, contractor licensing is not optional for most significant construction work. Verifying a license protects you.
Use CSLB’s official license check tool here:

CSLB also provides consumer guidance on hiring the right contractor here:

Beyond licensing, ask about insurance and how the contractor protects homeowners throughout the project.
