How Many Toilets Does OSHA Require?
The rule is 1926.51(c)(1), and it scales with crew size. Up to 20 workers, you need 1 toilet facility. From 20 to 199 workers, it is 1 toilet seat and 1 urinal per 40 people. At 200 or more, that ratio drops to 1 per 50. This applies to construction sites specifically. If your operation is general industry rather than construction, the ratio comes from a different rule, 1910.141(c)(1)(i), so know which category your job falls under before you order units. A crew building a mixed-use project near downtown New Rochelle at 35 workers needs 1 seat and 1 urinal per 40, which usually means two combined units on site. Our how many porta potties do I need guide walks through the math by headcount. For pricing once you know the count, check porta potty rental cost or get exact numbers through a quote request.
Does OSHA Have a Placement Distance Requirement?
OSHA does not set a specific foot distance from the work area to the toilet in 1926.51(c)(1) itself; it focuses on ratio and access, not a fixed number of feet. What it does require is potable water on site under 1926.51(a)(1), and general housekeeping under 1926.25 that keeps travel paths to the unit clear of scrap and debris. Practically, that means placing units where workers can reach them without crossing active equipment lanes or unbarricaded excavation. If site access is tight, our porta potty placement guide covers ground clearance and setup distance from curbs and driveways. Roll-off deliveries need about 60 feet of straight clearance behind the truck, which matters if you are staging a construction dumpster near the same access point. For crews in New Rochelle working close to Mamaroneck, about 4.2 miles east, or Scarsdale, 6.8 miles north, the same access rules apply regardless of which side of the city line the job sits on.
Cal OSHA Portable Toilet Requirements Construction: Does That Apply Here?
Cal OSHA is California's state plan and does not govern job sites in New York. New Rochelle contractors follow federal OSHA under 1926.51(c)(1) for construction toilet counts, not the California standard. If you have crews working across state lines, do not assume the ratios match; Cal OSHA's construction toilet rule differs in structure from the federal version. For a New Rochelle site, federal OSHA is the standard that inspectors will cite. If you are staffing a farm labor crew instead of a construction crew, the applicable federal rule shifts again, to 1928.110, which sets one facility per 20 hand-labor employees within a quarter mile walk. Our farm and agricultural restrooms page covers that distinction if your operation blends field work with a build site. Get the classification right first; the ratio and the rule both depend on it.
What Other OSHA Rules Apply Beyond Toilet Count?
Toilet count is the headline, but a few adjacent rules get missed. 29 CFR 1910.141(d)(2) requires washing facilities stocked with soap and towels or a hand-drying device; hand sanitizer alone does not satisfy it. That is separate from 1926.51(f)(1), which kicks in specifically where workers apply paints, coatings, herbicides or insecticides, or handle other contaminants: on those jobs you need washing facilities beyond a general handwashing station. Our handwashing station rental and handwashing requirements pages break down which setup satisfies which rule. Lighting matters too: 1926.56(a) sets minimum illumination for construction areas, relevant if your toilets sit in a low-light zone during winter shifts, covered further in porta potty in winter. If the site has an accessibility requirement, ADA Standards 213.2 requires at least 5 percent of clustered single-user units be accessible, never fewer than one; see ADA accessible porta potty and ADA restroom requirements for the specs.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$400 | not offered |
| deluxe | $85-$1200 | $150-$290 | not offered |
Weekend rentals for a standard unit run $125 to $400, useful for a short punch-list job rather than a full-month build. Compare durations on porta potty rental per day or monthly porta potty rental before you commit to a term.
How many porta potties do I need for a 20 person crew?
One toilet facility covers a crew of 20 or fewer under 1926.51(c)(1). Once you cross 20 workers, the ratio changes to 1 seat and 1 urinal per 40 people. Our standard porta potty rental page has unit specs if you are sizing beyond a single toilet.
Is hand sanitizer enough to meet OSHA handwashing rules?
No. 29 CFR 1910.141(d)2) requires soap and towels or a hand-drying device; sanitizer alone does not satisfy it. See portable sink rental for a compliant setup that includes running water.
Do OSHA rules require an accessible unit on every site?
Not on every site, but ADA Standards 213.2 requires at least 5 percent of clustered units be accessible, minimum one. Rye sits 8.1 miles east if you are comparing accessible unit availability across nearby New Rochelle service zones.
What triggers the 1926.51(f)(1) washing requirement?
Applying paints, coatings, herbicides or insecticides, or working around similar contaminants, triggers it specifically. It is not a general handwashing mandate for all trades. Check hand sanitizer station rental for what supplements, rather than replaces, that requirement.
Does New Rochelle require a permit for portable toilet placement in the right of way?
Placement in the public right of way needs confirming directly with the City of New Rochelle; check our porta potty permit requirements page before delivery day.
