A like-for-like garage door swap in San Francisco usually doesn't need a permit. Same size door, same opening, no structural work. Change the opening, touch the framing, convert the garage, or fold the door into a soft-story retrofit, and you're most likely into permit territory. SF DBI has the final word for your address, and our written quotes flag which kind of job you have either way.
This question comes up on almost every replacement quote we write in the city. One thing up front: we're a garage door shop, not the Department of Building Inspection. Rules change, and they hinge on details of your property. What follows is how it has worked on the jobs we see. Treat it as a map and let DBI be the final word.
The most common job in San Francisco is an old sectional or one-piece door coming out and a new sectional door of the same width and height going into the same opening, with the framing untouched. On jobs like this, a separate building permit hasn't been part of the process. It's treated like replacing a window with an identical unit: a maintenance-level improvement, not construction.
Same goes for the parts behind the door. New springs, tracks, cables, and a replacement opener on an existing door are repair work. Most of our door replacements fall in this bucket, and for those the paperwork is zero. The word "most" is doing real work in that sentence, so keep reading.
The moment the job stops being "a door" and starts being "the building," permits come into play. Four situations cover nearly all of them.
Call SF DBI or use their online permit tools, and describe exactly what you're doing: "replacing an existing garage door, same size, no structural changes" versus "enlarging the opening." Ask whether a permit is required. DBI's property lookup also shows open permits and whether your building sits in the soft-story program. It's a short conversation, and having asked is worth a lot when you sell. Unpermitted structural work is a classic escrow headache.
Part of every site visit is looking at what the job touches. If it's a clean like-for-like swap, we say so in writing. If anything pushes the job toward permit territory, we flag it on the quote before you commit, so the question gets answered before demolition. That includes an opening you want widened, a header that needs work, retrofit steel in the garage, or signs of a conversion. We've worked on enough Sunset rowhouses, Noe Valley retrofit garages, and Marina soft-story buildings to know where the tripwires are, and we're insured for the work we do.
What we won't do is play building department. We flag, and you (or your contractor or architect on bigger projects) confirm with DBI. That division of labor protects you.
For the door itself, no. A new single door in San Francisco starts at $1,200 installed either way, and our cost guide breaks down what raises the price. What a permit scenario adds is the project around the door: city fees, possibly engineered drawings, and a contractor for the structural work, which can cost several times what the door does. That's why it pays to know which kind of job you have before you start. Sometimes the smart move is a like-for-like swap now and the opening remodel later, with proper plans.
Same door size, same opening, no structural work: usually no permit. Anything that changes the opening or is part of a conversion or seismic retrofit: assume a permit until DBI tells you otherwise.

On jobs where the door is part of a larger permitted project, like an opening change, conversion, or retrofit, the general contractor or architect running that project handles permits, and the door installation happens under their scope. For a standalone job, ask SF DBI who files for your situation. What we commit to is flagging the question in writing on the quote so it gets answered before any work starts.
Swapping an opener on an existing door has been treated as repair work, the same category as replacing springs or cables. One related note: California requires battery backup on newly installed residential openers, so any new unit we install comes equipped for that regardless of permit questions. If your opener swap is part of a bigger garage project, check with SF DBI about the whole scope.
It comes up more often than you'd think, usually during a sale or a retrofit assessment. If the old work was a like-for-like door swap, there's nothing to unwind. If the opening itself was altered, an inspector or structural engineer can assess it, and SF DBI has a process for legalizing existing work. We can tell you what we see mechanically, whether the framing and hardware look right for the door. The permit-history side belongs with DBI and your own records.
