Hiring a Concrete Contractor in San Francisco, California
California law requires concrete contractors to hold a license from the Contractors State License Board (CSLB). Concrete contractors are classified as C-8 (Concrete Contractor) or C-29 (Masonry Contractor) depending on the work. Before hiring, verify the contractor's license status at the CSLB website using their license number or business name.
Many concrete projects in San Francisco require a building permit. The California Building Standards Code mandates that structures be permitted before construction begins. Code requirements vary by city and county, so check with your local building department to confirm what your project needs.
When you contact a contractor, ask whether they hold the proper license classification for your work, whether they obtain permits, and what your responsibilities are. Get the estimate in writing and verify the contractor's license before signing a contract.
