In California, general contractors must hold a state license issued by the Contractor State License Board (CSLB). The CSLB classifies contractors into several license types, including General Building Contractor (Class B) and Residential Remodeling Contractor (Class B-2), along with specialty licenses for specific trades. Before hiring any contractor, verify their license status and type on the CSLB website at cslb.ca.gov.

Most building and construction work in San Francisco requires a permit from the city's building department. According to the California Building Standards Code, no structure may be erected, constructed, enlarged, altered, or demolished without a separate permit. Code requirements vary by location, so confirm with the San Francisco building department what permits your specific project requires.

When evaluating a contractor, ask to see their license and check its status online through the CSLB. Request references, a detailed written contract that outlines scope, timeline, and costs, and proof of insurance. Understanding the license classification for your project type will help you identify the right contractor for the work.
