What makes a porta potty ADA accessible?
An ADA unit is bigger than a standard porta potty, and everything inside it is placed to a spec, not just eyeballed. The door opening has to clear 32 inches per ADA Standards 404.2.3, and the path leading to the door needs a 36 inch clear width the whole way, per section 403.5.1. Inside, the floor has to be stable, firm and slip resistant under section 302.1, which is why a wobbly base or soft ground under the unit is a real problem, not a cosmetic one. Reach ranges matter too: fixtures like the hand sanitizer dispenser or paper towel holder need to sit within 48 inches high and no lower than 15 inches, per section 308.2.1, and anything you operate, like a door latch, has to work with one hand and take no more than 5 pounds of force under section 309.4. First Choice Porta Potty stocks these to spec on the ADA accessible porta potty line, which is the unit we deliver whenever a cluster order comes in for Aurora. It is worth comparing against the standard porta potty rental and the deluxe flushable porta potty to see what changes and what doesn't.
How many ADA units do I need for my site?
The rule is simple: at least one accessible unit per cluster, and never fewer than one, even if your cluster is small. ADA Standards 213.2 sets that 5 percent minimum, rounded up to one unit whenever the math comes out below that. If you're running six standard units at a build site off a road in Aurora, you need at least one of those six to meet the accessible spec, not an extra unit on top. This is different from the total headcount math under OSHA portable toilet requirements, which is driven by worker count under OSHA 1926.51(c)(1): one toilet facility for 20 workers or fewer, then one seat and one urinal per 40 workers as the crew grows past that, up to one per 50 once you hit 200 workers or more. Figuring both numbers together is easier with the breakdown on how many porta potties do I need, and once you have a count, request a quote and we will split it into standard and ADA units correctly.
Where do accessible units need to be placed?
Placement is not just about fitting the unit somewhere flat. The route to the unit needs the same 36 inch clear width as the doorway itself, and if there is any grade change, a ramp on that path cannot run steeper than 1:12 under ADA Standards 405.2. That rules out plopping an ADA unit at the top of a curb cut or across loose gravel on a slope, both of which show up on Aurora job sites more than people expect. Our porta potty placement guide walks through firm, level pads and drainage, and for construction sites specifically, the illumination standards in OSHA 1926.56(a) matter too if the unit gets used during early or late shifts. If the unit sits anywhere near a public sidewalk or right of way in Aurora, that placement needs confirming with the city directly. We have not verified a specific Aurora ordinance for right-of-way placement, so treat that as a call to the city before delivery, not an assumption. Event planners running something at a public venue should also check porta potty permit requirements ahead of the date.
Do ADA units cost more to rent?
Yes, a bit, but not dramatically. The table below shows current bands.
| unit | day | week |
|---|---|---|
| standard | $100 - $350 | $130 - $500 |
| ada | $200 - $400 | $240 - $400 |
An ADA unit rented by the day runs higher than a standard unit rented by the day, and week-long ADA rentals run higher still, since a longer hold on an accessible unit costs more than a single day. For a full breakdown across durations, see porta potty rental cost and porta potty rental per day. If your job runs long, monthly porta potty rental pricing is worth asking about directly, since month-long ADA orders aren't in a public band and get quoted per job. Construction crews juggling ADA units alongside dumpsters and fencing should look at construction site services for how those get bundled.
How many ADA units do I need if I have 40 workers on site?
At 40 workers, OSHA 1926.51(c)(1) puts you at roughly two toilet facilities under the ratio, and ADA Standards 213.2 means at least one of those needs to be accessible. Confirm your exact worker count with us and we will size the cluster correctly.
Does an ADA porta potty need its own handwashing station?
Not automatically, but many sites pair one anyway. Handwashing rules under 29 CFR 1910.141(d)(2) require soap and towels, not sanitizer alone, so see handwashing station rental or handwashing requirements for what qualifies.
Can I rent just one ADA unit for a small event?
Yes. Even a single-unit event in Aurora needs that one unit to meet accessible spec under ADA Standards 213.2 if it's the only restroom on site. Check event restroom rental for event-specific sizing.
Is a restroom trailer an alternative to an ADA porta potty?
Sometimes. An ADA-compliant stall inside a restroom trailer rental can satisfy the same clearance and reach rules, and options like the 2 stall restroom trailer often include one built to spec.
What is the turning space requirement inside an ADA unit?
ADA Standards 304.3.1 requires a 60 inch diameter turning circle inside the unit. First Choice Porta Potty's ADA units are built to that dimension, unlike a standard unit sized for one user at a time.
