Hiring a Concrete Contractor in San Francisco, California
In California, concrete work typically requires a permit from your local building department. According to the California Building Standards Code, most structures must obtain a separate permit before work begins. San Francisco has its own building department with specific code requirements, so before you hire a contractor, check with the city about whether your project needs a permit. This applies whether you're building a new driveway, slab, or patio, or repairing existing concrete.
Concrete contractors in California are classified by the Contractors State License Board (CSLB) as C-8 (Concrete Contractor). Before hiring, verify that your contractor holds a valid California license. You can check a license online through the CSLB website by entering the contractor's license number or business name. This step lets you confirm their status and review any complaint history.
When you call a concrete contractor, ask whether they handle permits and grading for your project, as these are often handled separately. Clarify the timeline for curing and any finish options available to you. Get the details in writing before signing a contract.
