In California, electricians must hold a state license. The licensing classification for electrical work is C-10 Electrical Contractor. Before hiring, verify that your electrician holds a current, active license by checking the California Contractors State License Board (CSLB) online license lookup tool at www.cslb.ca.gov. You can search by license number or contractor business name.

Most electrical work requires a building permit from your local building department. According to the California Building Standards Code, no structure may be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted, or demolished unless a separate permit has been obtained from the building official. Code requirements vary by city and county, so contact the San Francisco building department to confirm what is needed for your project.

When selecting an electrician, ask whether they hold a current C-10 Electrical Contractor license, whether your project requires a permit, and confirm they will pull the permit if required. Review the contractor's license record on the CSLB website, which includes complaint disclosure information. Get a written contract before work begins and review it carefully.
