In California, most electrical work requires a building permit. According to the California Contractors State License Board (CSLB), no building or structure may be erected, constructed, altered, repaired, improved, or converted unless a separate permit has first been obtained from the building official. Code requirements vary by city and county, so check with your local building department to find out what's needed for your project in San Francisco.

Electricians in California must hold a C-10 Electrical Contractor license. Before hiring, verify the contractor's license through the CSLB online license lookup tool. You can search by license number (which appears on their pocket license) or by business name. This check will show you the license status and any complaint disclosures.

When you contact an electrician, ask whether they have obtained or will obtain the required building permit for your work. A licensed contractor should be familiar with permit requirements and code compliance for your specific project—whether it's rewiring, a panel upgrade, EV charger installation, or another electrical service.
