Most residential jobsites and backyard events do not need a city permit for a single portable toilet placed on private property, and a standard unit needs only about 44 by 48 inches of ground space to sit on. The line that trips people up is the public right of way: curb, street or sidewalk placement is NOT VERIFIED here and needs confirming with the City of St. Louis before delivery day.
It depends where the unit sits. On your own driveway or yard, most homeowners never touch a permit desk. Once a roll-off dumpster or a standard porta potty rental has to sit in the street, on a sidewalk, or in a lane that affects traffic, that is public right of way, and St. Louis city rules on obstructions are the ones that matter, not ours. We are St. Louis Porta Pros, and we tell every customer the same thing: private lot, low friction; street or curb, call the city first. This is true whether you are asking about a dumpster permit for a home renovation in University City, 7.9 miles northwest, or a construction dumpster on a downtown lot. Jersey City, Delaware and other markets run their own separate right-of-way rules, and if your job spans state lines, do not assume St. Louis Porta Pros terms cover a Delaware porta potty rental or a dumpster permit in another jurisdiction. Confirm locally every time. For dumpster-specific questions, our dumpster permit requirements page and what cannot go in a dumpster page cover load and placement basics separate from the right-of-way question.
OSHA does not regulate where a toilet sits on a public street, but it does regulate whether workers have one close enough to use. OSHA 1926.51(c)(1) sets ratios for construction sites: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass 20, and per 50 workers at 200 or more. That rule drives most of our how many porta potties do I need conversations. Beyond headcount, placement rules are mostly practical: keep the unit on stable, level ground, leave clearance for our pump truck, and do not block a fire lane. ADA Standards section 213.2 requires that at least 5 percent of a cluster of single-user units be accessible, never fewer than one, which matters on any ADA accessible porta potty job in St. Louis. Our full porta potty placement guide and OSHA portable toilet requirements pages go deeper on spacing and ground conditions.
A temporary power pole permit is a real thing in most cities, separate from any sanitation permit, and it is not something we issue. If your event or build needs a temporary power pole alongside a light tower rental, check with the utility and the city electrical inspector before the pole goes in. Fencing is simpler in most cases: a temporary fence rental or chain link temporary fence on private property typically avoids permitting, but a fence line that crosses a sidewalk or right of way brings you back to the same city desk as dumpster and toilet placement. OSHA 1926.202 requires barricades on a jobsite to meet ANSI D6.1, which is a safety standard, not a permit. If you are running crowd control barrier rental for an event in Webster Groves, 8.6 miles southwest, or Kirkwood, 12.5 miles west, the barrier standard travels with the equipment; the permit question stays local to whichever municipality hosts the event.
Keep everything on private land if you want the simplest path. A driveway, a fenced yard, a construction lot behind the property line: these rarely need a city sign-off for a portable toilet rental, a storage container rental, or a 10 yard dumpster rental. The moment equipment sits on a street, curb cut, or public sidewalk in St. Louis, treat it as a right-of-way question and call the city desk rather than guess. A roll-off delivery needs about 60 feet of straight clearance behind the truck, which usually pushes placement toward a driveway or open lot anyway. For events with heavier footprint, like a festival restroom rental or marathon and race restrooms, venue staff in Florissant, 15.4 miles north, or Chesterfield, 19.2 miles west, often already have a placement plan on file from prior years, so ask the venue first.
If it sits on a public street, sidewalk or curb lane in St. Louis, yes, likely. On private property, no. This is the single biggest gap between what customers assume and what the city checks. Confirm placement with the city before delivery if you are unsure.
Usually not, since a driveway is private property. Street placement is different and needs a check with St. Louis before the truck shows up. See our dumpster permit requirements page for load and placement notes that apply regardless of permit status.
One toilet for 20 or fewer workers, per OSHA 1926.51(c)(1). Above 20, add a toilet seat and urinal per 40 workers, and per 50 once you reach 200 workers. Our how many porta potties do I need guide walks through the math.
No separate permit exists for ADA units. ADA Standards section 213.2 just requires at least one accessible unit in a cluster, and section 304.3.1 requires a 60 inch turning circle inside it. See ADA restroom requirements for the full spec list.
