ADA-compliant porta potty: what are the turning space dimensions?

An ADA-compliant portable toilet must provide a wheelchair turning space of at least 60 inches in diameter or a T-shaped space per section 304 of the 2010 ADA Standards for Accessible Design. This interior space allows a wheelchair to complete a 180-degree turn, which is a requirement, not a recommendation. The door must also open outward and have accessible hardware, and the unit must include grab bars mounted at specified heights.

Standard versus ADA units: A standard portable toilet does not meet these turning space requirements. Only a designated ADA-compliant portable toilet is built with the larger interior dimensions, lower toilet seat height, and other features like an accessible door latch and proper clearance around the toilet.

Cluster rule: When placing multiple units at an event, the ADA 5 percent cluster rule applies. If you have a cluster of 20 standard units, you need at least one ADA unit. For a large festival with alcohol and food service on grass, ensure the ADA unit is on level ground with firm access for both users and the service truck.

Verification: Don't assume all large units are compliant. Check for the International Symbol of Accessibility on the door and measure the interior if possible. For long-term rentals or high-traffic events, consider a restroom trailer with an accessible stall, which often provides more space and amenities like flushing toilets and sinks.
