Who Can Apply and Do the Work
DBI accepts kitchen and bath permit applications from the property owner or a contractor holding a California B (general building) licence. The owner or B contractor can hand off the related electrical and plumbing permits to the trade contractors, who finish them in their own PermitSF accounts, and each trade permit is paid on its own scope.
What You Need Before the Permit Is Issued
- The online route only works if no walls are removed or moved, the building is an R-3 home or a unit in an R-2 apartment building constructed before 1991, and the bathroom being remodeled was legally permitted.
- A layout change, wall removal or legalizing an unpermitted bathroom needs two sets of plans prepared by a designer, architect or engineer, submitted in person for over-the-counter review.
- New bathrooms in existing homes also qualify for over-the-counter review, so adding a bath does not automatically mean a long in-house plan check.
- Your address must exist in the San Francisco Property Information Map; if it does not, you request a new address and pay a fee before applying.
What Else to Know in San Francisco
The electrical and plumbing permits that go with a bath permit skip intake when started from the PermitSF bath application, but the remodel itself cannot get its final inspection until both trade permits have passed final. B contractors authorized for DBI Express Permits can skip city staff review on the online route, which helps explain why half of the permits below were issued within a day of filing. Buildings that are not R-2 or R-3 go to in-house review instead.
