How many ADA units does an event need?
At least one, always, if the event is open to the public. Past that the figure planners use is five percent of the total restroom count, rounded up. Twenty units on a festival ground means one accessible unit as a floor and two is the safer read. If your event is ticketed and private the legal picture is different, but the practical answer usually is not.
Is the ADA unit bigger than a standard?
Wider, not taller. It is a broad square cabin instead of the narrow upright a standard is, because the whole point is a turning circle inside. Budget about five feet of clear width for the unit and its door swing. It weighs more, so the truck needs a reasonable approach — worth mentioning if the spot is up a slope.
Does it flush?
The standard accessible unit is a non-flush cabin, same tank principle as a regular standard. If you need a flush and accessibility together, the honest answer is a restroom trailer with an ADA-compliant stall and a ramp, which is a different product and a different price. We will walk you through both on the call.
Does the accessible unit work on desert gravel or turf?
It can sit there, but sitting there and being usable are different things. A wheelchair needs a firm route to the door, so on turf or loose gravel we would want a mat run or a placement at the edge of pavement. Tell us the surface when you book and we will work out the placement with you.
Do I need one on a construction site?
If a worker on that site needs an accessible unit, yes. Beyond that specific case, general-industry sanitation rules govern how many units of any kind a crew needs rather than mandating an accessible one. Plenty of contractors add one anyway on sites with visiting inspectors or client walkthroughs.
