OSHA requires 1 toilet for every 20 workers on a job site with 20 or fewer employees, per OSHA 1926.51(c)(1). Above that, the ratio shifts to 1 toilet and 1 urinal per 40 workers. Bayonne contractors planning construction site services need this number before they call for a quote.
The rule is OSHA 1926.51(c)(1), and it is a headcount table, not a guess. Crews of 20 or fewer get 1 toilet seat. From 20 up to 200 workers, add 1 toilet seat and 1 urinal per 40 people. At 200 or more, the ratio loosens to 1 seat and 1 urinal per 50 workers. There is no separate "Cal OSHA portable toilet requirements construction" standard for New Jersey sites; federal OSHA governs here, and the same headcount math applies whether the crew is framing in Bayonne or working a site 9.8 miles north in Harrison. The standard also calls for potable water under OSHA 1926.51(a)(1), which is a separate obligation from toilet count. A lot of GCs bundle both into one standard porta potty rental order plus a water station, since the inspector checks both. If your crew works with paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in a washing facility requirement on top of the toilet count, and that is a different obligation than general sanitation. For projects that need a walkthrough of exact math, our how many porta potties do I need guide breaks the table down by crew size, and OSHA portable toilet requirements as a topic ties back to every job site page we run.
Count workers, not square footage. A 15-person framing crew needs 1 unit under OSHA 1926.51(c)(1). A 45-person crew crosses into the 40-worker bracket and needs 2 units minimum, one with a urinal. Bayonne sites near the waterfront or industrial corridors often run larger crews, so do the headcount before ordering. Standard units run 100 to 350 dollars a day, with weekly rentals landing between 130 and 500 dollars depending on service frequency and duration. Monthly rates for longer builds sit in the 125 to 325 dollar range. Here is how the standard unit breaks down:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
ANSI/PSAI Z4.3 sets the baseline service interval at once weekly for up to 10 users over a 40 hour week, which is why crews above that number often add a second unit rather than stretch one tank thin. If your site needs an accessible unit alongside standard ones, ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, never fewer than one. Check our ADA accessible porta potty page for specs, and see porta potty rental cost for a full pricing breakdown across unit types.
Placement needs stable, firm, slip-resistant ground under ADA Standards section 302.1, and that applies even when the unit itself is a standard non-accessible model, because tipping and sinking are safety issues either way. OSHA does not publish a fixed "portable toilet distance requirement" in feet from the work area, but 1926.51(c)(1) implies reasonable access, and most site supervisors in Bayonne place units within a short walk of the active work zone, not tucked behind a fence line workers avoid. If you are placing units near a public sidewalk or roadway, right-of-way placement needs confirming with the city before delivery; we do not know Bayonne's specific rule on that and will not guess. Our porta potty placement guide covers ground clearance and setup basics, and delivery trucks generally need about 60 feet of straight clearance behind the unit, the same clearance a roll-off dumpster rental truck needs when it backs in. If your unit sits near a construction gate, pair it with a temporary fence rental so the toilet and the work zone stay contained together. For sites running a mobile office alongside the crew, a storage container rental or mobile office trailer rental often sits next to the restroom cluster for convenience, not because any rule requires it.
Yes, and it is easy to miss. 29 CFR 1910.141(d)(2) requires washing facilities to have soap and towels or a hand-drying device; hand sanitizer alone does not satisfy it. That standard applies to general industry workplaces, while OSHA 1926.51(f)(1) covers construction crews specifically working with paints, coatings, herbicides or insecticides. If your Bayonne crew is doing any of that work, a standalone handwashing station rental or portable sink rental covers the gap that a toilet unit alone does not. Some crews add a hand sanitizer station rental as a supplement, but it does not replace the soap-and-towel requirement under 1910.141. Our handwashing station requirements page walks through which standard applies to which job type. For crews running agricultural or hand-labor operations, a separate field sanitation rule under OSHA 1928.110 sets a facility within a quarter mile walk, one per 20 employees, which is worth knowing if your Bayonne site borders farmland or does landscaping work; see farm and agricultural restrooms for that setup.
A 25-person crew falls into the 20-to-200 bracket under OSHA 1926.51(c)(1), which requires 1 toilet seat and 1 urinal per 40 workers. At 25 people, that means 1 combination unit is the floor, though many supervisors add a second for wait times.
No. Cal OSHA is California's state plan and does not apply in Bayonne. New Jersey construction sites follow federal OSHA 1926.51(c)(1) for toilet counts, the same standard used across the state.
OSHA does not publish a fixed distance in feet. 1926.51(c)(1) requires the facility be provided and accessible; most contractors place units within easy walking distance of active work to avoid lost time and compliance headaches.
Only when required by the project or contract, but if you are clustering multiple standard units, ADA Standards section 213.2 requires at least 5 percent to be accessible, never fewer than one, once units are grouped.
OSHA 1926.51(c)(1) sets toilet counts by crew size. 1926.51(f)(1) requires washing facilities specifically for paint, coating, herbicide or insecticide work. 29 CFR 1910.141(d)(2) separately requires soap and towels, not sanitizer, at general industry washing stations.
