ADA cluster rule for 15 portable toilets at a November 2026 festival

The ADA cluster rule requires at least one ADA-compliant portable toilet in any cluster of 15 standard units at your November 2026 festival. 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 requirements. For 15 units, 5 percent rounds to one unit. This ADA-compliant unit must be identified with the International Symbol of Accessibility and provide a wheelchair turning space of at least 60 inches in diameter.

Event layout and unit types
Your festival layout with clusters of units is correct for managing crowd flow. A typical cluster might mix standard units (non-flushing, holding tank) with one ADA-compliant unit. For higher traffic areas or VIP sections, consider adding deluxe units (flushing bowl, sink, mirror) or a restroom trailer (towable building with flushing toilets, sinks, power and water hookups). Ensure all clusters follow the 5 percent rule independently.

Placement and access
Place each cluster on level ground with clear truck access for weekly service. November weather may require winterization measures like antifreeze in tanks to prevent freezing. For events with alcohol or food service, increase unit counts beyond baseline guidelines to reduce lines.

Invite questions on specific cluster layouts, unit mixes, or accessibility details.
