Planning

How many porta potties do you need?

Count by guests, hours, and whether the bar is open.

Rule of thumb

1 unit per 50 guests

For an event of up to 4 hours. Plan 1 per 35 guests for 4 to 8 hours.

Alcohol

Add 1 for every 3

If the table says 6 units and alcohol is served, book 8.

Public events

5% must be accessible

At least 1 ADA unit per cluster of up to 20 units, under ADA section 213.2.

Jobsites

1 unit per 10 workers

OSHA's legal minimum is 1 toilet for 20 or fewer workers. Weekly service keeps 1 per 10 working.
