Hiring a General Contractor in San Francisco, California
In California, building permits are required for most home improvement projects. According to the California Building Standards Code, no building or structure may be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished without a permit from the local building official. Code requirements vary by city and county, so check with your San Francisco building department to learn what permits your project needs.
California general contractors must hold a state license. Before hiring any contractor, verify their license through the Contractors State License Board (CSLB). The board maintains an online search tool where you can look up a contractor's license number or business name to check their status and view complaint history. A California contractor license number contains only numbers (no letters) and is up to 8 digits long.
When you call Trejo Construction at (415) 233-5610, ask whether they hold a state contractor license and what classification it carries. Request their license number so you can verify it through CSLB. Discuss which permits your specific project will require and confirm that the contractor will handle permit applications and inspections.
Do I need a building permit for kitchen or bathroom remodeling?
Most kitchen and bathroom remodels require permits in San Francisco. Contact your local building department to confirm permit requirements for your specific project. [3]
How do I verify a California contractor's license?
Visit the Contractors State License Board (CSLB) online license search tool and enter the contractor's license number or business name. The search will show the license status and any complaints on file. [4]
What license classifications do general contractors in California hold?
California has several contractor classifications. General Building Contractors (B), Residential Remodeling Contractors (B-2), and General Engineering Contractors (A) are common for remodeling and addition work. Ask your contractor which classification they hold. [1]
Should I ask the contractor about permits before signing a contract?
Yes. Ask whether permits are required for your project, who will obtain them, and how permit costs are handled. A licensed contractor should be familiar with local permit requirements. [2, 3]
