Do I need a permit for a kitchen remodel in San Francisco?

A San Francisco kitchen remodel almost always requires a DBI permit — any time the work alters gas piping, relocates plumbing, modifies electrical circuits beyond like-for-like, changes partition walls, or reconfigures ventilation, you are inside the permit envelope.

The SF Building Code adopts the 2022 California Building Code with SF amendments, and §105 (Permits Required) governs scope. SFBC §105.2 lists the narrow set of work exempt from permit — and a kitchen remodel almost never qualifies because it pulls in plumbing, electrical, and mechanical trades that have their own permit triggers under SF Plumbing Code §106, SF Electrical Code §89.106, and SF Mechanical Code §106.

When a permit is required:

• Cabinet-and-countertop refresh, no plumbing/gas/electrical moves, no partition changes — sometimes runs OTC at DBI's permit counter (1660 Mission Street) or via the online Permit Center.
• Adding circuits, moving the sink, relocating the range, adding a hood vent through an exterior wall — full DBI plan review, typically 6–14 weeks.
• Removing a wall between the kitchen and adjoining room — structural review under SFBC §1604 because almost every wall in SF Edwardian/Victorian stock is bearing or shear-critical. A licensed structural engineer's drawings + calcs are required.
• Gas line work — separate permit and pressure test by a SF-permitted plumbing contractor under SF Plumbing Code §1208.
• Range hood ducted to exterior — Mechanical permit and Planning Department sign-off if the new vent penetration is on a street-facing or historically rated facade.

Condominium owners must also clear HOA architectural review and may trigger SF Rent Ordinance §37.2 obligations if the building has two or more units permitted before June 13, 1979. Historic-district properties require a Certificate of Appropriateness for any visible exterior change (new vent, new window, condenser placement) before DBI can issue.

Skipping the permit is a misdemeanor under SFBC §103A.3.5, and unpermitted kitchen work is the single most common reason SF home sales fall out of escrow — buyers' inspectors flag it, lenders reject the appraisal, and the seller pays double-fee retroactive permit costs.
