In California, most construction work requires a building permit. According to the California Contractors State License Board (CSLB), no building or structure may be erected, constructed, altered, repaired, or improved without a permit first obtained from your local building official. Code requirements vary by city and county, so check with your local building department—in this case, South San Francisco's—to confirm what permits your project needs.

Before you hire a contractor, verify their license through the CSLB online license check tool. A contractor license number contains only numeric characters (up to 8 digits) and appears on their plastic pocket license. You can search by license number, business name, or the contractor's name. This step confirms their status and reveals any complaint disclosures.

When selecting a general contractor, ask whether they hold the appropriate CSLB classification for your project scope. California recognizes several classifications, including General Building Contractor (B), Residential Remodeling Contractor (B-2), and General Engineering Contractor (A), among others. Clarify whether the contractor will perform the work themselves or use subcontractors, and ensure all terms—scope, timeline, and payment—are in a written contract before work begins.
