Licensed contractors in San Francisco

The 13 businesses above are independent companies, each licensed by the California State License Board. The city on each card is where the business is based; all of them state service beyond their home city, so confirm coverage for your address when you call. You can verify any license, including its status and classification, at cslb.ca.gov.

San Francisco Contractors: questions
Every contractor on this page lists its CSLB license number. Enter it at cslb.ca.gov to see the license status, expiry date, classifications, bonding, workers' compensation and any complaint disclosure. A license that is not "current and active" is a reason to stop.
Each states service beyond its home city, which is why they are listed by region rather than by city. The city shown on each card is where the business is based. Confirm coverage for your address when you call.
Most pay from savings, a home equity line of credit, or contractor-arranged financing. A home equity line leaves an existing first mortgage untouched, which matters if yours is from before 2022, and it draws as invoices come due rather than funding the whole estimate on day one.
These are the requirements for the home equity line we place. Other lenders set their own guidelines, and some are more flexible.
