To verify that any electrician you hire is properly licensed in California, you can check their status through the California Contractors State License Board (CSLB). Electricians in California hold a C-10 Electrical Contractor license. Before signing a contract, look up the contractor's license number or business name on the CSLB online license checker to confirm their credentials and view any complaint disclosures.

Most electrical work in California requires a building permit from your local building department. Requirements vary by city and county, so contact the San Francisco building department to learn what permits your project needs. Your electrician should coordinate with your local building department to ensure all necessary permits are obtained before work begins.

When hiring an electrician, ask for their California license number, confirm they carry the appropriate C-10 classification, and verify their standing with the CSLB. Request a written contract that outlines the scope of work, timeline, and costs. Check references and understand your local permit requirements—your electrician should explain which permits apply to your job and who will handle obtaining them.
