What makes a porta potty ADA-accessible?
An ADA accessible porta potty is built bigger and laid out differently than a standard unit. Ann Arbor Porta Pros stocks units that meet the clearance and reach numbers spelled out in the ADA Standards, not just a wider door. The door opening has to clear 32 inches minimum under ADA Standards 404.2.3, and the path getting to it needs a clear width of 36 inches per ADA Standards 403.5.1. Inside, there has to be room for a 60 inch turning circle, per ADA Standards 304.3.1, so a wheelchair user can actually maneuver, not just squeeze through the door. Controls and the toilet paper holder need to sit where someone can reach them without twisting or gripping hard: ADA Standards 309.4 caps operable force at 5 pounds and rules out pinch-grip hardware. Reach range matters too. ADA Standards 308.2.1 sets the forward reach zone at 15 to 48 inches off the ground. The floor under all of it has to be stable and slip-resistant per ADA Standards 302.1, which is why we set these units on level pads, not on a slope or loose gravel. If you are budgeting, the porta potty rental cost page breaks down what an ADA unit runs against a standard porta potty rental.
How many ADA units does my Ann Arbor site need?
The rule is one accessible unit for every cluster of standard toilets, with a 5 percent floor, per ADA Standards 213.2. Picture a construction job in Ann Arbor with eight standard units grouped at one gate. Five percent of eight rounds down to less than one, but the "never fewer than one" clause in 213.2 still applies, so that cluster needs at least one accessible unit. Add a second cluster somewhere else on the same site and that group needs its own accessible unit too. Clusters are evaluated separately, not lumped into one sitewide count. This is separate from the total toilet count required under OSHA 1926.51(c)(1), which sets ratios like one toilet for 20 workers or fewer on a construction crew. You need both numbers to pencil out: total units under OSHA, and the accessible share of each cluster under ADA. Our how many porta potties do I need guide walks through both calculations side by side, and it is worth running before you call in an order for a construction site services package.

Do event restrooms in Ann Arbor need ADA units too?
Yes. Any public-facing event in Ann Arbor with clustered restrooms, not just construction sites, falls under the same ADA Standards 213.2 ratio. A wedding, a festival, a marathon route with restroom stops along the way, a golf tournament with galleries at every hole: if you're grouping units, at least one in each cluster has to be accessible. We deliver ADA units regularly for event restroom rental bookings across Ann Arbor, and we see it most on festival restroom rental and wedding restroom rental jobs where a client assumes a handful of standard units covers the requirement. It doesn't, once you're clustering. Ramp access matters here too: if an accessible unit sits above grade even a little, the ramp slope can't exceed 1:12 under ADA Standards 405.2. On uneven Ann Arbor park sites, that sometimes means a longer ramp run than people expect, so we plan placement ahead of the walkthrough rather than the morning of. Pricing on ADA units runs by the day or by the week; see the table below before you request a quote.
| unit | duration | typical price |
|---|---|---|
| ada | day | $230 |
| ada | week | $185 |
Weekly pricing on ADA units often lands lower per-day than a single day rental once you're renting more than a couple of days, so multi-day events usually book the week rate. A weekend rental for a standalone ADA unit typically runs around $240, separate from the day and week figures above.
Where should ADA units go on the site?
Placement drives whether a unit is actually usable, not just present. The porta potty placement guide covers grading, but for ADA units specifically: put them on the flattest ground you have, close to the accessible parking or accessible entrance, and skip anything that requires crossing gravel or a curb without a ramp. Ann Arbor sites with sloped lots, which is most of them given the terrain, sometimes need a leveling pad trucked in ahead of delivery. A roll-off dumpster rental or a temporary fence rental sharing the same footprint can also block the required clear path, so walk the layout before delivery day, not after. If your event or job site is actually just outside Ann Arbor proper, in Pittsfield 6.1 miles south or Ypsilanti 6.4 miles east, the same ADA Standards apply regardless of which side of the line you're on. We deliver to both.
Does a portable restroom trailer need to meet the same ADA rules?
Yes, if units are clustered. A restroom trailer rental, including 2 stall and 4 stall models, still needs an accessible stall meeting the same door width, turning circle and reach specs as a standalone ADA porta potty.
Can I rent just one ADA unit for a small Ann Arbor job?
Yes. ADA Standards 213.2 requires at least one accessible unit regardless of cluster size, so a small crew or a single-cluster event still needs one. Pair it with standard porta potty rental units for the rest of the crew.
What is the difference between ADA and deluxe units?
ADA units meet accessibility specs: door width, turning space, reach range. A deluxe flushable porta potty adds comfort features like a flush mechanism and a sink, but isn't automatically ADA-compliant unless it also meets the same clearance numbers.
Do construction sites and events use the same ADA ratio?
Yes, ADA Standards 213.2 doesn't distinguish by site type. Both a job site under OSHA 1926.51(c)(1) and a public event use the same 5 percent, minimum one, rule for clustered units.
