ADA Accessible Porta Potties: What Event Organizers Need to Know
Short answer
Where portable toilets are grouped at an event open to the public, the 2010 ADA Standards require at least 5 percent of the units in each group, and no fewer than one, to be accessible. An accessible unit has a wide outward-swinging door, grab bars and room to turn a wheelchair, and it needs a firm, level route to reach it.
If you're running an event that's open to the public, accessible restrooms aren't optional. But the rules can seem vague until you know what to look for.
This guide covers when you need accessible units, how many, what makes a unit accessible, and the placement mistake that trips up a lot of organizers.
When do you need accessible units?
Events open to the public are generally covered by the Americans with Disabilities Act, and restroom facilities are part of that. If your event needs a permit, the permit will often spell out accessible restroom requirements, and reviewers commonly check.
Private events aren't always covered the same way, but if you have older guests or anyone with mobility needs, an accessible unit makes the day easier for them.
How many accessible units do you need?
The 2010 ADA Standards say that where portable toilets are grouped together, at least 5 percent of the units in each group, and no fewer than one, need to be accessible. That's where the common "one in twenty" planning figure comes from.
In practice: if you have one group of 10 units, at least one is accessible. If you have three groups spread across the site, each group needs its own accessible unit. Always check your permit, because it may ask for more.
What makes a unit accessible?
- A wider door that swings outward, so it doesn't block the inside.
- Enough floor space inside to turn a wheelchair.
- Grab bars placed to help with transferring to and from the seat.
- A seat at a suitable height.
- A ground-level or ramped entry, depending on the model and how it's set up.
Why does the path to the unit matter?
It's one of the most common mistakes in event plans: an accessible unit placed at the end of a soft lawn, across loose gravel or up a slope. The unit is accessible, but nobody in a wheelchair can reach it.
The route to the unit needs to be firm, stable and reasonably level, without steps or curbs. Paved paths, compacted ground or temporary ground matting all work. Keep the area in front of the door clear so there's room to open it and turn.
Who else uses accessible units?
Accessible units also help parents with small children and strollers, caregivers helping someone, and anyone who needs more space. That's another reason not to hide them at the edge of the site.
A quick placement checklist
- Firm, level route from the main walkway to the unit, with no steps or curbs.
- Clear space in front of the door so it can open fully and a wheelchair can turn.
- One accessible unit at each group of units, not all in one place.
- A handwashing station nearby that's also reachable from a wheelchair.
- The unit marked with the International Symbol of Accessibility so people can find it.
