ADA cluster rule: two porta potties at a small park, need ADA?

Two portable toilets in a park need one ADA-compliant unit if they are clustered together. The ADA cluster rule requires 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. For two units, this means at least one must comply with the ADA Standards for Accessible Design. This rule applies regardless of park size or event type, as it is a federal accessibility standard for public accommodations.

The ADA cluster rule in practice: A cluster is any group of units placed together for user convenience, such as two standard units side by side in a park. Even if the park is small and sees low traffic, the rule mandates accessibility. The accessible unit must provide a turning space for wheelchairs, proper door width, grab bars, and other features specified in the 2010 ADA Standards.

What this means for your park: Replace one of the standard units with an ADA-compliant portable toilet. Ensure it is placed on level ground with firm, stable surface access. Check local permit requirements, as some cities have additional rules for public park placements, including distance from playgrounds or water sources. Service and maintenance for the ADA unit follow the same schedule as standard units, typically weekly pumping and cleaning.
