Hiring a Concrete Contractor in San Francisco, California
In California, concrete contractors must hold a state license. The Contractors State License Board (CSLB) classifies concrete work under a C-8 license. Before you hire a contractor, verify they hold an active license—this protects you and ensures the work meets state standards.
You can check any contractor's license status online through the CSLB. Look up the business by name or license number on their website to confirm the license is current and to review any complaint disclosure. Before signing a contract, the CSLB recommends reading their Hiring a Contractor guide.
