Hiring a General Contractor in San Francisco, California
California requires general contractors to hold a license from the Contractors State License Board (CSLB). Before you hire, check the contractor's license status online at cslb.ca.gov using either their license number or business name. This lookup will show you whether the license is active and any complaint history.
In California, the type of license a contractor holds matters. The most common are General Building Contractor (Class B), General Engineering Contractor (Class A), and Residential Remodeling Contractor (Class B-2). Each classification reflects the scope of work the contractor is legally permitted to perform, so confirm the contractor holds the right license for your project type.
Most remodels, additions, and structural changes in San Francisco require a building permit from the city. California law requires a separate permit before any building work begins. Check with the City and County of San Francisco's building department about what your specific project needs before signing a contract.
How do I check if a contractor's license is active?
Visit cslb.ca.gov and use the online license lookup tool. You can search by license number or business name. The tool will show the license status and any complaint history. [4]
