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

Yes, you need an ADA-compliant portable toilet for a cluster of four units in a public 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. For four units, this means at least one ADA-compliant unit is required, identified with the International Symbol of Accessibility.

The ADA cluster rule applies to any temporary installation in a public space, including parks, events, or construction sites. It ensures equal access for individuals using wheelchairs or mobility devices. The rule is not optional; it's a federal requirement under the ADA, and local jurisdictions often enforce it through permits.

What an ADA unit provides includes a wider door (at least 32 inches clear), interior turning space of 60 inches diameter, grab bars, and an accessible toilet seat height. Standard units do not meet these specifications. If your cluster includes only standard units, you are not compliant.

Planning your order for a public park involves more than just the ADA rule. Consider the expected number of visitors, duration (e.g., a weekend event or long-term installation), and whether food or alcohol is served. For a small cluster, one ADA unit and three standard units is a common setup. Ensure the ground is level and that a vacuum truck can access within 25 feet for servicing.

If you have details on the park's usage or local permit requirements, share them for more specific advice.
