Porta Potty Rental for Weddings in Phoenix
A wedding for 150 guests over 6 hours with a bar plans for about 4 restroom stations when you pro-rate the PSAI 500 guest row and add the alcohol bump. Many couples cover that with one restroom trailer plus an accessible unit. Mesa does not treat weddings as special events, and a Pinal County owner's own wedding is exempt from the event permit.

Weddings are where restroom choice shows. Desert venues and backyard ceremonies around Scottsdale, Cave Creek and the East Valley often rely on trailers because guests are dressed up and the night runs long.
Even when no permit is needed, guests with disabilities still need an accessible option. Plan it in from the start.
