San Francisco Street Space permit for a porta potty
In San Francisco, anything that sits on the public right-of-way — a dumpster, scaffolding, a porta potty — needs a permit from Public Works. Here's how it actually works.
Quick answer
If the unit sits on a public sidewalk or in a parking lane, you need a Street Space permit from SF Public Works (Bureau of Street-Use & Mapping). If it sits on private property — a lot, a driveway, inside the fence — you don't. Permits are issued online, priced per linear foot per month, and typically take a few business days.
When you need it
The permit covers 'occupation of the public right-of-way' for construction-related items. You need one when:
- The unit will sit on the sidewalk, in a parking space or in a traffic lane.
- A debris box, scaffold or material storage is sharing the same street frontage (one permit can cover all of it).
- You're doing a remodel on a lot with no yard or driveway — the classic Mission / Noe Valley situation.
When you don't
No permit when the unit is entirely on private property: a fenced job site, a driveway, a backyard, a parking lot you control. Most Bay Area jobs fall here. If you can close the gate on it, you're fine.
The half-sidewalk rule
A standard Street Space permit lets you occupy up to half the sidewalk width, and you must keep a clear pedestrian path (generally 6 feet on commercial corridors, 4 feet minimum elsewhere). A standard unit is about 4 feet wide, so on a narrow residential sidewalk it often doesn't fit — in that case the parking lane is the usual answer, which requires the 'parking lane' variant and 72-hour no-parking signage.
ADA path of travel is enforced: never block a curb ramp, a bus stop, a fire hydrant or a blue-zone space.
How to apply
Applications go through Public Works' online permit portal. Have this ready:
- The address and a simple site sketch showing where the unit goes and the clear path.
- Dimensions: a standard unit is 44" × 48"; ADA 78" × 92". We provide spec sheets.
- Dates: permits run monthly; renewals are straightforward.
- Contractor license number and a certificate of insurance naming the City.
- Fees are per linear foot of frontage per month plus an application fee; expect roughly $100–$400/month for a single-unit footprint depending on the zone. Check the current fee schedule on the Public Works site.
Timeline and tips
Simple sidewalk permits are often issued in 2–5 business days; parking-lane occupancy takes longer because it goes through SFMTA for the no-parking posting. Apply before you order the unit — we'll hold your delivery date without charge.
Tell us the permit is in progress when you book; our driver carries a copy, places the unit inside the permitted footprint and photographs the placement for your records.
Frequently asked
How much does an SF Street Space permit cost for a porta potty?
Fees are charged per linear foot of frontage per month plus an application fee. A single-unit footprint usually lands between $100 and $400 per month depending on the zone. Public Works publishes the current schedule.
Can I put a porta potty on the street in San Francisco without a permit?
No. Units on the sidewalk or in the parking lane without a permit get tagged and can be removed at your cost. On private property no permit is needed.
How long does the permit take?
Sidewalk-only permits: typically 2–5 business days. Parking-lane permits need SFMTA no-parking signs, so allow 1–2 weeks.
Does PottyLine handle the permit?
We provide the spec sheets, insurance certificate and placement photos, and we'll walk you through the portal. The application has to be submitted by the permittee (you or your contractor).
