OSHA portable toilet requirements for construction sites, set out in 1926.51(c), establish the baseline: one toilet for 20 workers or fewer, then a seat and a urinal added per 40 workers up to 200, and per 50 workers after that. There is no OSHA portable toilet distance requirement written into the rule itself, only the headcount ratio. Portsmouth Heights contractors sizing a crew of 15 need just one unit to start.
The rule is 1926.51(c), and it scales with headcount, not site size. A crew of 20 or fewer gets one toilet facility, period. Push past 20 and you add a toilet seat and a urinal for every 40 workers, and that ratio holds until you cross 200 employees, where the ratio eases to one seat and one urinal per 50. Water matters too: 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, so a site with only standard portable toilets still needs a separate drinking water plan. Most residential jobs and small commercial builds around Portsmouth Heights fall well under the 20 worker line, which keeps the math simple. Bigger jobs, like a multi-crew build near Chesapeake, 20.5 miles south, need a real headcount plan before delivery, not after. If you are not sure where your crew lands, run the numbers on our how many porta potties do I need page before you order. Crews working under a state plan sometimes ask about cal osha portable toilet requirements or cal osha portable toilet requirements construction specifically; Virginia sites fall under federal OSHA, not California's state plan, so the ratio above is the one that governs here. Renting the wrong count is the most common and most avoidable mistake on a jobsite, and it is worth ten minutes to get right the first time through construction site services planning.
Count workers, not square footage. Fifteen employees means one standard unit. Forty-five employees crosses the 20 threshold, so you owe a toilet plus a seat and urinal combo under 1926.51(c). Field crews on farms or ag sites follow a different rule: 1928.110 sets one facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters for anyone running farm and agricultural restrooms out past Carrollton, 15.8 miles northwest. Ratios aside, planners still have to think about turnover, distance to work zones and whether the crew is split across trailers or one open lot. A porta john rental placed at the wrong end of a long site does nobody any good, even if the count is technically correct. For crews with any disabled workers or public-facing events, ADA Standards 213.2 requires at least 5 percent of clustered single-user units to be accessible, never fewer than one, which is where an ADA accessible porta potty earns its spot on the order.
Placement drives usability more than the ratio does. OSHA does not hand out a fixed distance number in 1926.51(c) itself, but practical access still has to work: a 60 inch turning circle per ADA 304.3.1 near any accessible unit, a stable, slip resistant surface under ADA 302.1, and a clear route at least 36 inches wide per ADA 403.5.1. Our porta potty placement guide walks through firm ground, delivery clearance and distance from work zones in more detail. Roll-off trucks need about 60 feet of straight clearance behind the unit to position a container, so plan toilet placement around that same lane if you are also running a roll-off dumpster rental on the same lot. Lighting counts too: OSHA 1926.56(a) sets minimum illumination for construction areas, which matters for winter jobs with early sunsets, something worth reading up on in porta potty in winter. If the unit sits anywhere near a public sidewalk or right of way in Portsmouth Heights, confirm placement with the city directly. That rule is not settled here, so check before you set anything down and see porta potty permit requirements for what to ask.
No, they run under a separate standard, and the distinction trips people up constantly. General toilet counts fall under 1926.51(c). Handwashing tied to paint, coatings, herbicides or insecticides falls under 1926.51(f)(1), which only applies when those contaminants are actually present on site, not as a blanket handwashing mandate. General industry sites, as opposed to construction, follow 1910.141(c)(1)(i) for toilet ratios instead. Either way, 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at any washing station, and hand sanitizer alone does not satisfy it. That is a real gap on plenty of sites that only stock a hand sanitizer station rental and call it done. A proper handwashing station rental or portable sink rental closes that gap, and our handwashing requirements page breaks down which standard applies to which job. Painting crews, sealcoat crews and anyone spraying herbicide near Smithfield, 20.7 miles northwest, should plan for 1926.51(f)(1) specifically, not assume a general toilet order covers it.
Renting the right mix matters more than hitting a number. A standard porta potty rental runs a measured $100 to $350 a day depending on term, and a deluxe flushable porta potty or restroom trailer rental fits crews that need something closer to a real bathroom. Check current bands on our porta potty rental cost page before you commit to a count.
| unit | day | week | month |
|---|---|---|---|
| standard | 100-350 | 130-500 | 125-325 |
| ada | 200-400 | 120-240 | -- |
| deluxe | 85-1200 | 150-290 | -- |
No fixed distance appears in 1926.51(c) itself. The standard sets ratios by headcount, not spacing. Practical placement still matters for access and turnaround time, which our porta potty placement guide covers with ADA clearance figures included.
Once you cross 20 workers, 1926.51(c) adds a toilet seat and a urinal per 40 employees. A 25 person crew needs one toilet plus that combo unit, not just a single stall.
State plans can add requirements beyond the federal minimum, but this page cites only verified federal standards. Portsmouth Heights sits under Virginia jurisdiction, not California, so Cal OSHA rules do not apply here directly.
Events are not construction workplaces, so 1926.51(c) does not strictly govern them, though many planners use it as a practical guide. See event restroom rental for ratio planning built around guest counts instead of employee counts.
Yes. Many Portsmouth Heights job sites order both on one delivery run. Check storage container rental or storage container rental cost to bundle a container with your restroom order and save a trip.
