ADA cluster rule: six porta potties at a November 2026 festival. Need an ADA unit?

Yes, a six-unit cluster at a public festival requires one ADA-compliant portable toilet to meet the 2010 ADA Standards for Accessible Design. The ADA cluster rule (section 213.2, Exception 2) mandates that where multiple single-user portable toilets are clustered, at least 5 percent must be accessible. With six standard units, that 5 percent calculation means at least one must be an ADA-compliant unit. This is not a recommendation, it is a federal requirement for public events to ensure equal access for attendees using mobility devices.

Event Planning Basics
For a festival with 200 to 380 attendees over several hours, six total units (five standard and one ADA-compliant) is a reasonable starting point if alcohol is served. Add more units if the event runs all day or has food vendors, as lines will form quickly. Place the cluster on level ground with clear access for the vacuum truck on service days.

ADA Unit Features
An ADA-compliant portable toilet provides a wider interior with a 60-inch diameter turning space, grab bars, an accessible door latch, and a lower urinal if included. It must be identified with the International Symbol of Accessibility. Do not block its access path with ropes, signs, or other obstacles.

Beyond the Minimum
Consider adding a handwash station near the cluster for hygiene, and if your budget allows, a restroom trailer with multiple stalls can reduce wait times and include an accessible compartment. Always check with your local permit office for any additional health department rules.
