Porta Potty Rental for Backyard Parties in Phoenix
A backyard party for 60 guests over 5 hours with drinks plans for about 2 units so guests stay out of the house. A flushing unit or a unit with a sink feels much nicer than a basic one for the same footprint.

Private parties at home usually need no event permit, but HOA rules may say where a unit can sit and for how long. Check before delivery day.
In Maricopa County, chemical toilets should not sit within 20 feet of occupied premises or 10 feet of a sidewalk unless authorized, so think about placement early.
