Porta Potty Rental for New Home Builds in Phoenix
A new home build with up to 25 trades on site at peak needs 2 toilets under the Maricopa County 1 per 20 rule, within 200 feet of the work. OSHA alone would allow 1 seat and 1 urinal. Subdivisions often stage units every few lots.

Trades come and go, so the peak count matters more than the average. Framing and drywall weeks bring the biggest crews.
On subdivision builds, keep units within 200 feet of active lots and move them as phases advance.
