A practical contractor-checking process
Ask who will contract for the work
Confirm the legal business or contractor name and ask for the California contractor license number that applies to the work.
Verify the license independently
Use the California Contractors State License Board's official service to check the current license status and classification. Status can change, so check close to the hiring decision.
Compare written scopes
Make sure each proposal describes the same equipment, quantities, assumptions, exclusions, permit responsibility and finish work before comparing price.
Discuss insurance and permits
Ask the contractor what insurance applies and whether a permit or inspection is expected. Requirements vary by project and local authority.
Understand payment and warranty terms
Read the written payment schedule, change-order process and any labor or manufacturer warranty before signing.
Keep project records
Retain the agreement, changes, invoices, permit documentation, equipment information and final approvals relevant to the project.
Official California resources
Use primary government sources for current license information and consumer guidance.
