Fall festival 2026: 500 attendees, 10 hours, food trucks. How many units?

Priya N.asked 0 viewsHow Many UnitsUnits per personFood serviceDurationAda cluster ruleRestroom trailer

I'm coordinating our city's annual fall festival for next year and starting the permit application. We expect around 500 attendees over 10 hours in a grassy park, with multiple food trucks serving all day. It's a family-focused event, so we'll have a lot of kids and parents. The ground is level, and a service truck can access the placement area easily. I need to figure out the restroom plan: how many standard units, how many ADA-compliant units, and whether to consider a restroom trailer for better comfort. What's the right mix for this duration with food service?

For your 500-attendee fall festival, plan for 10 to 12 standard portable toilets, one ADA-compliant unit, and consider a restroom trailer for comfort. Start with the units per person guideline of one unit per 50 to 75 people for a four-hour event, then add more for your 10-hour duration and food service. Food trucks mean higher usage, so lean toward the higher end. The ADA cluster rule requires at least one accessible unit per cluster, so include one ADA-compliant portable toilet. A restroom trailer offers flushing toilets and sinks, which families appreciate, but it needs level ground and power from a generator or hookup. Servicing depends on use: for a one-day event, units are delivered clean and serviced after, but if usage is heavy, a mid-event pump might be needed. Costs are driven by unit types, rental duration, service frequency, and add-ons like handwash stations.
