Special cases
Tankless water heaters
Tankless water heaters require backflow prevention assemblies. We will ask you about the assemblies when you apply for a plumbing permit.
Backflow prevention assemblies are part of San Francisco’s annual cross-connection control program. Learn more about cross-connection control.
Homeowners
Only owner-installers of stand-alone single family dwellings may apply for a plumbing or mechanical permit to do the work themselves. Check your home’s official status in the Assessor’s map.
If you cannot demonstrate that you can do the work safely, you will need to hire a licensed contractor.
