Hiring a General Contractor in San Francisco, California
California requires general contractors to hold a state license issued by the Contractors State License Board (CSLB). The two main license types for general building work are the General Building Contractor (Class B) for remodels, additions, and most home improvements, and the Residential Remodeling Contractor (Class B-2) for smaller residential remodel projects. Before signing a contract, verify that your contractor holds the correct license class for your scope of work.
You can check any contractor's license status—including complaint history—on the CSLB website at cslb.ca.gov. Search by business name or license number. This step takes minutes and protects you from hiring an unlicensed or disciplined contractor.
Most construction work in San Francisco requires a building permit. The California Building Standards Code requires a permit before any structure is erected, enlarged, altered, repaired, or demolished. Contact the San Francisco Building Department to confirm permit requirements for your specific project. Your contractor should be familiar with local code and permit processes.
How do I check if a contractor's license is valid?
Visit cslb.ca.gov, go to the Check a License page, and search by the contractor's business name or license number. You'll see their license status and any complaint disclosures. [4]
What license do I need for a remodel or addition?
Most home improvements require either a General Building Contractor (Class B) license or a Residential Remodeling Contractor (Class B-2) license, depending on the scope and cost of the work. Ask your contractor which class they hold. [1]
Will my project need a building permit?
According to California Building Standards Code, permits are required before erecting, enlarging, altering, repairing, or demolishing any structure. Code requirements vary by city and county. Check with the San Francisco Building Department to confirm what you need. [3]
What questions should I ask a contractor before hiring?
Ask for their license number and verify it on the CSLB website. Discuss whether they will handle permits or you will. Get everything in writing—scope, timeline, and cost—in a binding contract that complies with California law. [2, 4]
