At least one accessible unit is required whenever portable toilets are clustered on a Durham job site or event, per ADA Standards 213.2, which sets a minimum of 5 percent accessible units in any cluster and never fewer than one. Renting the right unit from Durham Porta Pros keeps you compliant from day one.
It comes down to space and reach, not just a bigger box. ADA Standards 304.3.1 calls for a 60 inch diameter turning circle inside the unit, enough room for a wheelchair to rotate fully. The door opening has to clear at least 32 inches per ADA Standards 404.2.3, and the path leading up to it needs a minimum 36 inch clear width under ADA Standards 403.5.1. Grab bars, a raised toilet seat, and interior hardware placed within the 48 inch high and 15 inch low reach range from ADA Standards 308.2.1 round out the build. Every ADA accessible porta potty we place in Durham is built to those numbers, not close to them. If your event or site also needs standard porta potty rental units alongside the accessible ones, we deliver both on the same run.
One accessible unit minimum, more if your total toilet count climbs. ADA Standards 213.2 sets the 5 percent floor, so a bank of 20 standard units still only requires one accessible unit, but a bank of 40 needs two. Layer that against OSHA 1926.51(c), which sets general toilet ratios for construction crews starting at one facility per 20 workers and adding capacity as headcount rises through 40 and then 200 workers. Our how many porta potties do I need guide walks through both counts side by side so you are not guessing on a Durham build with mixed crew sizes. Event planners in Chapel Hill, 9.6 miles southwest of Durham, and Morrisville, 13.5 miles south, ask us this same question for wedding tents and race staging, and the math works the same way regardless of the venue.
Ground has to be stable and the route to the door has to stay clear, full stop. ADA Standards 302.1 requires floor and ground surfaces that are stable, firm, and slip resistant, which rules out loose gravel or soft turf as a landing pad in Durham's wetter months. Door hardware and any operable parts need to work with one hand and no more than 5 pounds of force under ADA Standards 309.4, and a ramp serving the unit cannot exceed a 1:12 running slope per ADA Standards 405.2. Our porta potty placement guide covers the grading and clearance details specific to Durham lots and turf sites. If the surface at your Durham address will not hold a level pad, ask about our temporary fence rental options to mark and protect the approach route instead of skipping the ramp altogether.
The accessibility standard is the same either way, but the toilet-count rule layered on top of it changes. A construction crew falls under OSHA 1926.51(c) for its base toilet ratio, while general workplaces off a jobsite follow OSHA 1910.141(c)(1)(i) instead. Events do not answer to either OSHA standard for headcount, but ADA Standards 213.2 still applies the moment units are clustered for public use, so a festival in downtown Durham needs its accessible unit regardless of whether OSHA has jurisdiction. Our event restroom rental and construction site services pages break out the two paths separately so you order the right mix. Farther out, Wake Forest, 24.6 miles east of Durham, and Apex, 23.7 miles south, both fall under the same ADA floor no matter the event type.

Pricing sits above standard units because of the added interior space and hardware. For a full breakdown against standard and deluxe options, see porta potty rental cost or porta potty rental per day for shorter jobs.
Yes, if units are clustered for guest use, ADA Standards 213.2 requires at least one accessible unit regardless of guest count. This applies to wedding restroom rental and festival restroom rental bookings the same way it applies to construction. Skipping it is the most common compliance gap we see on Durham event sites.
Yes. A single accessible unit satisfies ADA Standards 213.2 for small clusters, and it pairs fine with standard porta potty rental units for the rest of the crew. Check your crew size against OSHA 1926.51(c) separately, since that ratio is not tied to the ADA count.
ADA units are built around clearance and reach standards; deluxe flushable porta potty units add flush mechanisms and interior finish but are not automatically accessible. Some jobs need both. Ask us which combination fits your Durham site before you order.
Some do, but not all trailer configurations include an ADA-compliant stall. Our restroom trailer rental and 4 stall restroom trailer options can include one on request. Confirm the accessible stall before booking if that unit matters for your Durham event.
Placement in the public right of way or requirements tied to a city permit need confirming directly with Durham's permitting office, since local rules vary by site. Our porta potty permit requirements page outlines what to ask them. Request a quote and we will help you plan the count.
