October 2026 craft fair: 200 attendees, mostly women, 8-hour day. How many porta potties?

For your October 2026 craft fair with 200 attendees over 8 hours, I would recommend at least five portable toilets: four standard units and one ADA-compliant unit. The ADA 5 percent cluster rule requires that when you cluster multiple single-user portable toilets, at least 5 percent (in practice, at least one) must be an ADA-compliant portable toilet. Since you have a crowd that is mostly women and the event lasts 8 hours, you will need more units than the base guideline of one per 50 to 75 people for a four-hour event. Food service also increases usage. Adding a deluxe unit or a restroom trailer can improve guest comfort but comes with higher costs due to features like flushing mechanisms, sinks, and for trailers, the need for power and level ground. Servicing for an 8-hour event is usually handled with a pre-event delivery and post-event pickup; the rental company may recommend a mid-event service if usage is heavy. Confirm any specific requirements with your city's special event permit office.
