What makes a porta potty ADA accessible?
It comes down to clearances, not just size. 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 fight. Inside, ADA Standards section 304.3.1 requires a 60 inch diameter turning circle so a user can rotate a chair fully before or after use. The floor has to meet ADA Standards section 302.1, meaning stable, firm and slip resistant, which rules out loose gravel pads or uneven ground under the unit. Grab bars, sink height and the toilet itself all sit within the reach ranges set by ADA Standards section 308.2.1, capped at 48 inches high and no lower than 15 inches. Door latches and flush mechanisms need to work with one hand and no more than 5 pounds of force, per ADA Standards section 309.4. Our ADA accessible porta potty units are built to that full spec, not a stripped-down version of it. If you are comparing it against a standard porta potty rental or a deluxe flushable porta potty, the accessible unit is simply larger inside to make room for that turning circle.
How many ADA units does my event need?
Start with your total unit count, then apply the 5 percent rule from ADA Standards section 213.2. If you are renting 12 standard units for a festival, that math rounds up to at least one accessible unit, and most planners round up further rather than land right on the line. Our how many porta potties do I need guide walks through headcount math for events, weddings and job sites, and it pairs well with OSHA portable toilet requirements if you're staffing a crew alongside guests. Construction sites in Scottsdale follow OSHA 1926.51(c)(1): one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you cross that threshold. Neither OSHA count nor the ADA ratio replaces the other, so a 60-person crew needs both an OSHA-compliant total and its own accessible unit under 213.2. We size this out for construction site services, event restroom rental, and wedding restroom rental jobs across Scottsdale the same way, working from the guest or crew count you give us.
Do I need an accessible unit for a small event?
Yes, if you have any portable toilets on site at all, at least one has to be accessible under ADA Standards section 213.2. There is no headcount low enough to skip it entirely once you place units in a public or semi-public setting. This applies whether you are running a backyard fundraiser in Scottsdale or a full festival restroom rental setup. Placement matters as much as unit choice. The accessible unit needs a level approach with a ramp slope no steeper than 1:12 under ADA Standards section 405.2 if there is any grade change, and a clear path at least 36 inches wide per ADA Standards section 403.5.1 leading up to it. We walk that route in person before drop-off, because a unit that meets every internal spec still fails if the path to the door crosses soft ground or a curb with no ramp. Our porta potty placement guide covers ground prep in more detail, and it is worth reading before your delivery day, especially if your Scottsdale site has any slope at all near the parking area.
What if my venue already has fixed restrooms?
Fixed restrooms do not automatically clear you of the portable accessible unit requirement, especially if the fixed facilities are far from the event area or already near capacity. Many Scottsdale venues bring in a restroom trailer rental instead of standalone units precisely because a trailer can house an ADA-compliant stall alongside standard stalls under one roof. Our 4 stall restroom trailer and 8 stall restroom trailer options both include an accessible stall built to the same door width and turning circle standard as our standalone units. For larger productions, a luxury restroom trailer or a dedicated shower trailer rental can also be configured with accessible fixtures. If your venue sits near Fountain Hills, about 16.6 miles southeast of central Scottsdale, or Paradise Valley, 15.4 miles southwest, we deliver the same compliant build regardless of which side of the metro you're on. Confirm any right-of-way placement with the city directly, since we have not verified Scottsdale's permit rules for curb or street placement, and our porta potty permit requirements page flags that gap rather than guessing.
Pricing for accessible units

Is one ADA unit enough for a wedding of 150 guests?
Usually yes, if you are running standard units alongside it. The 5 percent rule under ADA Standards section 213.2 rounds up from your total unit count, not your guest count, so a wedding needing 6 to 8 standard units typically needs just one accessible unit alongside them.
Can I rent just the ADA unit without any standard units?
Yes. Some Scottsdale job sites and small gatherings only need the one unit. It still meets every ADA clearance spec on its own, and pricing runs the same whether it's your only unit or one of a dozen.
Do ADA units cost more than standard units?
Yes, typically. Daily typical pricing runs higher for ADA units than standard units, mostly because of the larger footprint and reinforced grab bars. Weekly rentals narrow that gap. Check request a quote for your exact count and duration.
What happens if my site has a curb or slope near the unit?
We assess grade before delivery. ADA Standards section 405.2 caps ramp slope at 1:12, so we either place the unit where the ground is already level or bring ramping to close the gap. Flag any slope when you book.
Do construction sites in Scottsdale need an ADA unit too?
Yes, if any worker or visitor with a disability may need it, and OSHA 1926.51(c)(1) governs your total toilet count separately by crew size. The two rules stack rather than replace each other, so plan for both counts together.
