What makes a porta potty ADA accessible?
An ADA accessible unit is wider than a standard one, has a flat ground level entry with no step, a door wide enough for a wheelchair, interior grab bars, and enough clear floor space for a wheelchair to turn and transfer. The design follows the 2010 ADA Standards for Accessible Design. Call 1-833-520-0680 to order one.

What does the standard actually require?
The 2010 ADA Standards for Accessible Design set the dimensions that make a restroom usable by someone in a wheelchair: a clear entry with no step, a door wide enough to pass through, space inside to turn, grab bars positioned for a transfer, and hardware that can be operated without gripping or twisting.
An ADA portable unit is built to those dimensions. That is why it is roughly 5 by 5 feet rather than 4 by 4, and why the floor sits flush with the ground rather than on a raised skid.
How many should you order?
The common planning figure is about 5 percent of your total unit count, with a minimum of one. On a 20 unit festival that means one or two.
The more important rule is simpler: if the public can attend, order at least one. The cost difference on a single unit is small, and an event with no accessible facility is a real problem rather than a technicality.
Why does the route matter as much as the unit?
Because accessibility is a path, not a box. A perfectly compliant unit at the end of 30 feet of gravel or wet grass is not accessible to the person it was ordered for.
Plan a firm, level approach from the main event area. Ground protection matting is inexpensive and is often what turns a technically compliant order into a genuinely usable one.
Should you keep it reserved?
Yes, in effect, and the way to do it is to order enough standard units. ADA units get used by everyone when the queue at the standard units is long, which is a capacity problem rather than a signage problem.
Signage helps at the margins. Adequate standard capacity helps far more.
How does booking work?
Call with the headcount and dates
We connect you with a local provider. Tell them whether workers or guests will be using the units.
Confirm the count and the schedule
The provider sets the unit mix, the servicing frequency and the placement, then quotes the whole rental.
Delivery, servicing and collection
Units arrive clean. The service truck keeps to the agreed schedule, and collection is on the end date.
What does it cost?
| Market type | Typical range |
|---|---|
| Monthly, major metro | $225 to $425 |
| Monthly, mid size city | $200 to $375 |
| Monthly, smaller market | $180 to $340 |
What is inside the unit?
Included
- Ground level flat entry with no step
- Interior grab bars on both side walls
- 60 inch clear turning circle
- Toilet set at an accessible transfer height
- Low mounted paper holder and sanitiser within reach
- Door hardware operable with a closed fist
Servicing schedule
Weekly tank pumped, interior cleaned, consumables restocked, grab bars sanitised.- Per event delivered clean and stocked, with the access route checked on placement.
- Twice weekly on heavily used public sites, where turnover is high.
Fittings vary slightly between manufacturers. Your provider confirms what the specific unit includes and how often it will be serviced.
Where should the unit go?
The unit is only accessible if the route to it is. Put it on firm, level ground with a compacted or matted path from the main area, and never at the end of a gravel track or across soft grass.
A standard unit occupies roughly 4 by 4 feet with the door opening outward, so allow about 5 by 5 feet of clear space. The service truck needs to get within about 25 feet of the unit, which is the constraint that decides most placement questions.

ADA Accessible Porta Potty questions
How many ADA units do I need?
A common planning figure is about 5 percent of the total units, with a minimum of one. For any event the public can attend, order at least one regardless of size.
Is an ADA unit legally required?
Where an event is open to the public, accessible facilities are expected under the 2010 ADA Standards. Ordering at least one ADA unit is the practical answer for any public event.
How much bigger is it than a standard unit?
Noticeably. The footprint is about 5 by 5 feet against 4 by 4, and the interior provides a 60 inch turning circle for a wheelchair.
Can anyone use the ADA unit?
They can, but it should be kept available for the people who need it. Providing enough standard units is what keeps the accessible one free.
What about the path to the unit?
It matters as much as the unit. A firm, level, matted or compacted route is required; a unit at the end of a gravel path is not meaningfully accessible.
Are flushable ADA units available?
In many markets, yes. Accessible units with a flush and an internal sink exist and are worth asking about for weddings and formal events.
