How many porta potties do I need?

The rule our dispatch desk uses on every call.

1 per 50 guests per 4 hours

100 guests for 4 hours = 2 units. 100 guests for 8 hours = 4 units.

Add 1 unit per 5

Chart says 5 units and there is a bar? Book 6.

At least 1 accessible unit

ADA 213.2: 5% of units in each cluster at public events.

OSHA: 1 toilet per 20 workers

We recommend 1 unit per 10 workers with weekly service.
