San Francisco permits, simplified
DBI reviews every San Francisco building permit application for life-safety and code compliance, and work can’t start until the permit is issued. Many interior kitchen and bathroom remodels qualify for an over-the-counter permit, including layout changes submitted with plans, and registered general contractors can apply online for kitchen and bath remodel permits.
For ADUs, San Francisco offers a State program and a Local program with different rules and review paths. Local-program ADUs need in-house Planning review before the building permit is submitted, while qualifying State-program ADUs can use DBI’s Permit Review Roundtable for faster coordinated review. If you have an existing unit built without permits before 2013, the City’s Unit Legalization program may let you make it legal. We help you choose the right path.
Built for older San Francisco homes
Much of San Francisco’s housing was built long before modern seismic codes. We strengthen raised wood-frame homes with bolt-and-brace retrofits, and we find and repair the dry rot, termite damage and failing stucco that fog and age leave behind, especially in the western neighborhoods.
We also build out commercial spaces, including offices, retail and restaurants, with tenant improvement work planned around your lease and opening dates.

Jack and his crew did an excellent job on our addition. They walked us through every step of the job and went out of their way to make sure everything was done well. The foreman, Don, was always available to take our phone calls and answer questions. They are very pet friendly and always made sure our dog did not get out. We couldn’t be happier with our new master bedroom and bathroom. Bob D. San Mateo, CA

I have had so much work done by this company. Bathroom, electrical, redo of our bathing area with tile and new tubs, anything you need this company can pretty much do. There prices are very reasonable and you get great quality of stuff. A green home came in and got everything done in a timely manner. I will always use a green home for all 4 of our businesses.
