October 2026 festival: ADA unit placement on uneven ground?

Yes, an operator can level an ADA-compliant portable toilet on a gentle slope for safe wheelchair access. The operator will use wood blocking or composite leveling pads under the unit's base to create a level interior and a level approach path. The ADA Standards for Accessible Design require a level turning space outside the unit, so the operator must ensure the ground is stable and even around the entrance.

For your festival with 600 people per day over two days, plan more than the baseline guideline of one unit per 50 to 75 people because of the alcohol service and long duration. You will need multiple clusters of standard units with at least one ADA unit per cluster. Place each cluster on the flattest available ground within the sloped area. The service truck access is good; confirm the placement is within 25 feet of where the truck can park for pumping.

Prepare the site by clearing debris and marking the desired locations. Tell the rental company about the slope when you book so they send a crew prepared with leveling materials. I once saw an ADA unit placed on a slope without proper blocking; the door wouldn't stay open and the ramp was unstable. The operator had to return with extra equipment to fix it, which delayed setup. Proper site prep avoids that.
