Does the ADA cluster rule apply to three porta potties in a park?

Yes, the ADA cluster rule applies to three portable toilets in a park. The 2010 ADA Standards for Accessible Design require that where multiple single-user portable toilets are clustered at a single location, at least 5 percent of the units in each cluster must be accessible. With three units, that means at least one ADA-compliant portable toilet is required.

What is a cluster? A cluster is any group of portable toilets placed together to serve the same event or area. Your three standard units in the park qualify as a cluster, even for a weekend event.

What makes a unit ADA-compliant? An ADA-compliant portable toilet must have a wider door, interior turning space of at least 60 inches in diameter, grab bars, an accessible toilet seat height, and compliant door hardware. It must also be identified with the International Symbol of Accessibility.

Check local permits. Some city special event permits or park use agreements explicitly require ADA compliance. Even if your event is small, the cluster rule is a federal standard that applies to public accommodations. It's good practice to include an accessible unit whenever you have multiple toilets in one location.
