An accessible portable restroom needs a 60 inch turning circle inside, a door opening at least 32 inches wide, and a route to reach it that's 36 inches clear. St. Louis Porta Pros sets these units on job sites and events across St. Louis, and gets one placed within a normal delivery window when you order ahead.
Compliance comes down to a handful of measurements, not a sticker on the door. ADA Standards section 404.2.3 sets the minimum clear door opening at 32 inches, wide enough for a wheelchair to pass through without a shoulder turn. Inside, ADA Standards section 304.3.1 calls for a 60 inch diameter turning circle so a user can rotate a chair fully. The floor itself has to meet ADA Standards section 302.1, which means stable, firm and slip resistant, not the flexed plastic pan you get in a budget unit. Grab bars, a lowered paper holder and a wider bench seat round out the build. If you're comparing an ADA accessible porta potty against a standard porta potty rental, the footprint on the ground is close, but the interior clearance is what changes. For sites running a mixed fleet, decide the ADA count before you order the rest of your portable toilet rental so the accessible units aren't an afterthought squeezed in at the edge of the lot.
The rule is simple math once you know your total unit count. ADA Standards section 213.2 requires that where single-user portable toilets are clustered, at least 5 percent of the units be accessible, and never fewer than one. That means a St. Louis event running ten standard units still needs one ADA unit at minimum, and a fifty-unit festival deployment needs three. This stacks on top of the general sanitation ratio: OSHA 1926.51(c)(1) sets one toilet facility per 20 construction workers, scaling to one toilet seat and one urinal per 40 workers between 20 and 200, and per 50 workers above that. Run both numbers and take the higher unit count. Our how many porta potties do I need guide walks through the worker or attendee math step by step, and the OSHA portable toilet requirements page breaks down the construction-specific ratios in more depth. Event planners booking through event restroom rental or festival restroom rental should size the ADA count against expected attendance, not just crew size.
Placement matters as much as the unit spec. The accessible path to the unit needs a minimum 36 inch clear width under ADA Standards section 403.5.1, and if there's any grade change, a ramp can't exceed a 1:12 slope per ADA Standards section 405.2. That rules out setting an ADA unit on loose gravel at the far edge of a St. Louis lot with a curb in the way. Reach ranges matter too: ADA Standards section 308.2.1 caps a forward reach at 48 inches high with a 15 inch minimum low, which is why the paper holder and any dispenser inside sit lower than in a standard unit. Door hardware has to work one-handed under 5 pounds of force, per ADA Standards section 309.4, so a twist-lock latch doesn't pass. Our porta potty placement guide covers ground surface and clearance planning in general, and if your event spans a paved lot and a grass field, plan the ADA unit for the paved side. Sites also running a temporary fence rental should route the fence line around the accessible path, not through it.
Yes, typically. An ADA unit runs 200 to 400 dollars a day and 120 to 240 dollars a week in the measured range, against a standard unit's 100 to 350 dollars a day. Here's how the numbers line up:
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| standard | week | $200 |
| ada | day | $230 |
| ada | week | $185 |
A weekend ADA rental in St. Louis typically lands around 240 dollars, similar to the day rate since weekend pricing is its own short-term band. The porta potty rental cost page breaks down what drives the spread between standard and ADA pricing, and porta potty rental per day covers short-term jobs specifically. For longer projects, check monthly porta potty rental before committing to weekly renewals. Construction crews budgeting a full site setup should also look at construction site services to bundle fencing, dumpsters and restrooms into one delivery.
If you're the only person on site, ADA Standards section 213.2's 5 percent rule still technically applies once you're clustering units, but a single unit for a homeowner-only home renovation porta potty job rarely triggers it. Confirm with St. Louis Porta Pros if subcontractors will be on site too.
Yes. Some jobs need only one accessible unit, no cluster required. St. Louis Porta Pros delivers single ADA units for small events or job sites the same way as a standalone portable restroom rental order.
ADA units meet accessibility specs: wider door, turning circle, grab bars. A deluxe flushable porta potty adds flushing and a sink but isn't automatically ADA compliant unless built to those same dimensions.
Some do, depending on the model. Ask about an ADA-accessible stall when booking a restroom trailer rental or an 8 stall restroom trailer for a larger St. Louis event.
Placement in the public right of way needs confirming with the city before delivery. Check porta potty permit requirements or ask St. Louis Porta Pros directly when you request a quote.
