ADA cluster rule: three porta potties at a park, need ADA unit?

Yes, a cluster of three portable toilets in a city park requires at least one ADA-compliant unit under the ADA cluster rule. The 2010 ADA Standards for Accessible Design mandate that where multiple single-user portable toilets are clustered at a single location, at least 5 percent of the units in each cluster must comply with accessible toilet requirements. In practice, this means any cluster of two or more units needs at least one ADA-compliant portable toilet, identified with the International Symbol of Accessibility.

Standard unit details
A standard portable toilet is a non-flushing unit with a holding tank, roughly four feet square and seven feet tall. It serves basic sanitation needs but lacks accessibility features like a wider door, interior turning space, and grab bars.

ADA-compliant unit requirements
An ADA-compliant portable toilet provides a wider door (at least 32 inches clear), interior turning space meeting the 60-inch diameter circle or T-shaped space requirement, grab bars, and a seat at the correct height. It ensures wheelchair users can enter and use the facility independently.

Permit office checks
City permit offices review restroom plans for events in parks. They verify unit counts, confirm the presence of ADA units in clusters, check placement away from water and food areas, and ensure service schedules and removal deadlines are met. Always consult your local municipal rules, as requirements can vary.

For a park installation, consider ground conditions and truck access. Units must be on level ground within about 25 feet of where the service truck can park. If you have questions about your specific setup or local regulations, feel free to ask.
