ADA Standards section 213.2 requires that when single-user portable toilets are clustered on a site, at least 5 percent of the units must be accessible, and never fewer than one. That means a Richardson job site with 15 standard units needs at least one ADA unit, and a two-unit site still needs one. Richardson Porta Pros builds every order around that minimum.
Start with the 5 percent rule from ADA Standards 213.2 and round up, not down. A cluster of 20 standard toilets needs one accessible unit minimum, and a cluster of 40 needs two. This applies whether you are running a construction site services job downtown or a weekend build near the Telecom Corridor. If you are still figuring out total unit count before applying the ADA percentage, our how many porta potties do I need guide walks through worker counts under OSHA 1926.51(c) first, then layers the accessible requirement on top. Event planners running a festival restroom rental or marathon and race restrooms order in Richardson should size the whole fleet before locking the ADA count, since spectators and staff both count toward the total. We stock ADA accessible porta potty units separately from standard porta potty rental stock, so the ratio is easy to hit even on short notice. Rentals booked through request a quote get the accessible count checked against your total headcount before delivery, not after.
Compliance comes down to space, reach and door width, not just a wheelchair sticker on the door. ADA Standards section 404.2.3 sets minimum clear door opening width at 32 inches, and section 403.5.1 requires a 36 inch clear route leading to the unit. Inside, section 304.3.1 calls for a 60 inch turning circle, and section 308.2.1 limits forward reach to 48 inches high and 15 inches low so a seated user can reach handles and dispensers. Section 309.4 adds that any operable part, latches included, has to work with one hand and no more than 5 pounds of force, no tight grasping or twisting. Ground surfaces have to be stable, firm and slip resistant under ADA 302.1, which matters on the gravel and dirt lots common around Richardson build sites. Our ADA accessible porta potty units meet all five of these specs out of the yard. Compare that against a deluxe flushable porta potty or a stall inside a 2 stall restroom trailer, since trailer stalls need the same door and turning clearances if you are marketing the trailer as accessible.
Placement rides on the same 36 inch route rule as the unit itself. A ramp built to reach an ADA unit cannot exceed a 1:12 slope under ADA Standards 405.2, so a unit set on a curb or a pallet needs a long, gradual ramp, not a short steep one. Our porta potty placement guide covers ground stability and drainage before you settle on a final layout, and it pairs well with porta potty permit requirements if the unit sits anywhere near the public right of way, since placement in that strip needs confirming with the City of Richardson before delivery. Roll-off and trailer deliveries add another wrinkle: a roll-off dumpster rental needs about 60 feet of straight clearance behind the truck, and that clearance can conflict with an ADA route if the two are staged too close together. For weddings and private events, our wedding restroom rental and event restroom rental teams walk the site in Richardson before setup to confirm the accessible unit has a real path from parking, not just from the venue door.
Yes, ADA units run higher because of the extra floor space and hardware, but the gap is smaller than most people expect.
| unit | day | week |
|---|---|---|
| standard | $100 to $350 | $130 to $500 |
| ada | $200 to $400 | $240 to $400 |
A standard unit rented by the day typically lands near $150, while an ADA unit by the day typically runs closer to $230. Weekly ADA pricing runs higher than the daily rate, same as standard units, so it pays to ask for a mixed quote rather than pricing each unit type alone. Our porta potty rental cost page breaks down the full range across unit types, and porta potty rental per day covers short jobs specifically. For month-long builds, monthly porta potty rental pricing applies the same logic. Handwashing has its own compliance layer too: 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at any wash station, sanitizer gel does not satisfy that rule, and our handwashing station rental and handwashing requirements pages cover that separately from restroom accessibility.
OSHA 1926.51(c) sets toilet counts by worker headcount but does not itself set accessibility specs. ADA Standards section 213.2 is the rule that drives the 5 percent accessible minimum. Most Richardson job sites need to satisfy both: enough units for headcount, and enough accessible units for that same cluster.
Often yes, if the cluster is small. ADA 213.2 requires at least one accessible unit regardless of cluster size, so a two- or three-unit job site is covered by a single ADA unit. Larger sites need more, scaled at 5 percent of the total.
32 inches, per ADA Standards section 404.2.3. That is measured as clear opening width, not the full door panel. Our ADA units are built to that spec, along with the 36 inch approach route required under section 403.5.1.
Yes, if a stall is marketed as accessible it needs the same door width, turning circle and reach specs. Check our 4 stall restroom trailer and 8 stall restroom trailer pages for stall-by-stall accessibility details before booking.
Placement in the public right of way needs confirming with the City of Richardson directly; we have not verified a specific ordinance number for that rule. Our porta potty permit requirements page explains what to check before delivery day.
