Crew count at the peak
Count the largest number of people on site at once, subcontractors included. Maricopa County's rule counts persons on the project and OSHA's table counts employees, so the peak crew drives both.
Construction and remodels
Restroom trailers and porta potties for construction sites and remodels
A job site or remodel needs restrooms for everyone working there, for as long as the work lasts. We plan porta potties, hand-wash stations, or a restroom trailer around your crew size, work areas, site access, and schedule, with servicing and pickup set from the start.
Watch for these signs
When a job site needs restrooms
- A new build or site with no working restrooms yet.
- A remodel that takes a home's or building's restrooms out of service while crews or occupants are there.
- A large site with work areas spread far apart.
- A general contractor who needs one restroom plan for several trades.
Our services
What we plan with you
- Porta potties near each work area, or a restroom trailer where crews or occupants need one
- Hand-wash stations beside the toilets
- Placement near the work areas, with a route for the service vehicle
- Servicing on a schedule set for the length of the project
- Changes to the plan when crew size or project phase changes
- Coordination with the superintendent or on-site contact
Your options
Planning the setup
Crew size, distance, and servicing decide how a job-site restroom plan works. Settle these before delivery.
Distance to each work area
Maricopa County requires job toilets on or within 200 feet of each work area. On a spread-out site, that can mean porta potties in more than one spot instead of one trailer at the gate.
Servicing
A restroom only helps if it stays usable. Agree on a servicing schedule and keep a route open for the service vehicle as the site changes.
Occupied remodels
When people live or work in the building during a remodel, place the trailer away from the work zone, on a path occupants can use without crossing it.
Planning the work
What affects your quote
- Site address and access for delivery and servicing
- Project start date and expected length
- Peak crew size and number of work areas
- Servicing schedule
- Power and water at the placement spot
Job-site restroom rules in Maricopa County
Maricopa County's Environmental Health Code says construction, erection, alteration, repair, or razing projects need toilets "for the use of persons on the project in a ratio of at least one (1) toilet per twenty (20) persons," on or within 200 feet of each work area. OSHA's construction standard, 29 CFR 1926.51(c), sets its own table based on the number of employees. Our guide to how many toilets a construction site needs works through both with examples.
Under the 2010 ADA Standards, section 203.2, portable toilet units provided for use exclusively by construction personnel on a construction site do not have to meet the accessible toilet requirements. If anyone else will use the restrooms, ADA-accessible portable restrooms are available to add to the site.

Common questions
Before you book
Does a remodel count as construction under the county rule?
The county text names alteration and repair projects as well as new construction and demolition. If you are not sure your project is covered, ask Maricopa County Environmental Services.
Can the trailer stay for the whole project?
Yes. Tell us the expected length and we plan servicing for the full rental, then adjust the schedule and pickup date if the project timeline changes.
Who should be our contact for servicing?
Name one person on site, such as the superintendent, who can keep the service route open and tell us when the crew size or work areas change.
What if the site has no power or water yet?
Say so in your request. Porta potties need no hookups. For a restroom trailer, we confirm the exact power and water needs before delivery and talk through what the site has available.
Porta potties or a restroom trailer for a job site?
Porta potties suit open sites, spread-out work areas, and early phases with no utilities. A restroom trailer suits occupied remodels, office trailers, and long projects where people want an indoor-style restroom. Some sites use both.
