Mechanical Permits — San Francisco

SF Mechanical Permit

HVAC installs, changeouts, ductwork and ventilation — filed as the separate mechanical permit most cities require, not buried in another trade's paperwork.

What this covers

  • HVAC installs and like-for-like changeouts
  • Furnaces, air conditioners, heat pumps and rooftop units
  • Ductwork — new runs, repairs and ventilation
  • Equipment relocation, filed as the new install it is

How it works

  1. Talk to Tony — tell him the address and the scope. Two minutes, from the job site.
  2. We prepare and file the application through PermitSF, the city's portal.
  3. City fees pass through at cost — you see them before anything is filed.
  4. When the permit issues, we line up the inspection — the sequencing is on us to track, not you.

Good to know in San Francisco

  • Mechanical is a separate San Francisco permit — it does not ride inside a plumbing or electrical filing.
  • A changeout often needs a companion electrical permit. We flag the pair so neither filing stalls the other.
  • Only owners of stand-alone single-family homes may apply for their own mechanical permit, with a Permit Center help-desk visit shortly after applying. Everyone else files through a licensed contractor.

Who uses this

Licensed C-20 HVAC contractors, mechanical shops running changeout routes, and property managers keeping buildings comfortable across the city.

PermitsPros — we file permits. We never promise approvals — that's the city's call, and we tell you so up front. City fees are separate and paid by you directly to the city.
