Sanitation standards are not optional
Federal OSHA rules for construction (29 CFR 1926.51) require toilet facilities on construction sites, and the number required scales with the number of employees. As a general guide, the standard calls for one toilet for up to 20 workers, and one toilet seat and one urinal per 40 workers beyond that, with some exceptions for mobile crews. New Jersey public-works and local requirements may add to this. Always check the current text and your contract documents, and confirm with your safety officer. We are not a compliance adviser.
Even where no rule applies, a good ratio makes practical sense: queues at the one unit cost labor hours.
What contractors usually ask for
- Monthly or recurring rental terms rather than a single-event price
- Weekly (or more frequent) servicing, scheduled for the days the crew is on site
- Handwashing stations beside each restroom cluster
- Quick relocation as the work phases move around the site
- Units on a skid or tie-down for windy, exposed locations
- ADA-accessible units where project rules require them
Site conditions we plan around
Mud season, winter ice, and summer heat all affect placement and servicing. We recommend putting units on firm, drained ground with a clear approach for the service vehicle, away from active equipment paths and not blocking emergency routes.
For multi-phase projects, tell us when you expect to move or add units. If you may need to extend the rental, ask about long-term options at the start so extension terms are clear.
Laying out units across a changing site
A construction site is not static. The first weeks are about clearing and excavation, then foundations, framing, and finishing, and the spot that works early may sit in the path of a crane or a concrete truck later. Pick a location that stays usable for as long as possible, close enough to the work that crews actually use it, and away from the paths of heavy equipment.
On larger sites, a single bank can mean long walks, and long walks mean lost time. Consider two or more clusters, each with handwashing. On multi-story or phased work, think about how workers on upper floors or far corners will reach the units.
- Keep units off fresh fill, loose spoil piles, and trench edges
- Leave clear space for the service vehicle to approach and back out
- Avoid placing units where runoff will flow past them in heavy rain
- Tell us about site gates, lock-box codes, and quiet hours that limit service windows
- Mark units clearly on the site map used for deliveries and safety orientation
Paperwork to settle before the first shovel
Contractors working on public projects, large commercial builds, or jobs with owner-side requirements often have specific sanitation language in their contracts. Read it before ordering. It may call for particular numbers of units, accessibility, handwashing, or servicing intervals. Bring it with your call so we can match the plan to the paper. For the general OSHA background, see our construction sanitation guide, and confirm details with your safety manager or the authority.
In your rental agreement, check the term, how extensions are handled, who is responsible if a unit is damaged on site, and how relocations are requested. A short written note on who on your crew can authorize changes can prevent misunderstandings later.
Planning around the New Jersey calendar
Spring brings mud, especially on cleared lots and in the clay-heavy parts of the state, so firm access matters. Summer heat means the units are used more and need more attention. Winter work in North and Central Jersey means frozen ground, ice at the door, and snow piles that can block a service truck. If your project crosses seasons, ask early how servicing and access will be handled in each. On long jobs, see our page on long-term rentals.
Questions to ask before you book
- How many workers will be on site at peak, and for how many months?
- How often should the units be serviced, and on which days?
- Is there a site contact who can provide gate access for service trucks?
- Will the units need to be moved during the project?
