200-person corporate picnic with families: how many ADA units are needed?

You need at least one ADA-compliant portable toilet for your 200-person event, based on the ADA 5 percent cluster rule. The ADA count depends on the total number of units you order, not the guest count. For a four-hour corporate picnic with 200 people, food service, and a beer and wine bar, the planning guideline suggests starting with about three to four total units. Alcohol and a mixed-gender crowd mean you should add more units. Order at least four total units, which includes the required ADA unit.

Families with children do not change the ADA math, but they increase the need for total units. Children use restrooms more frequently. A deluxe portable toilet with a sink is a good addition for a corporate event. Place all units together in one cluster on level ground with clear access for the service truck. Service is not needed for a four-hour event, but the rental company will deliver and pick up the units. The rental cost is driven by the unit types, the rental duration, and the delivery distance.
