OSHA portable toilet requirements for construction sites in Des Plaines run through 1926.51(c): 1 toilet for 20 workers or fewer, more units once the crew passes that number. Contractors searching osha portable toilet distance requirements often expect a footage number, but there's no separate distance rule in the regulation itself. Get the count wrong and it's the foreman who hears about it first.
Start with the headcount on site, not the trailer size. OSHA 1926.51(c) breaks it down plainly: 1 toilet facility for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you're between 20 and 200 people, and 1 seat plus 1 urinal per 50 workers at 200 or more. A 15-person framing crew in Des Plaines needs one standard porta potty rental. A 60-person site needs to run the math again, and most contractors round up rather than argue with an inspector later.

If you're bidding a job now, request a quote with your crew size and we'll size it before delivery day.
Field sanitation for agricultural operations runs different math entirely. OSHA 1928.110 calls for one facility per 20 hand-labor employees, positioned within a quarter mile walk, with potable water and handwashing alongside it. That standard shows up more on the farm and agricultural restrooms side of our business than on a downtown Des Plaines build site, but the ratio logic is the same: count heads, then place units close enough that nobody skips the walk.
OSHA doesn't publish a hard footage number for how far a toilet can sit from the work area. What it does require is potable water under 1926.51(a)(1), and if your crew is spraying paints, coatings, herbicides or insecticides, washing facilities under OSHA 1926.51(f)(1). That last rule gets misquoted as a general handwashing mandate. It isn't. It applies specifically to those contaminant contexts, so a framing crew pouring concrete doesn't trigger it, but a crew stripping old paint does.
Placement still matters for the reasons that show up on every jobsite walkthrough: units need firm, level ground and a path a service truck can reach. Our porta potty placement guide covers ground prep, and if you're near a public sidewalk or right of way in Des Plaines, that placement needs confirming with the city before delivery, since we don't carry municipal permit rules in this fact bank. For general questions on what's allowed, our porta potty permit requirements page is the place to start, and dumpster permit requirements covers the roll-off side if you're running both on the same site.
Not automatically, but the paint and chemical trigger under 1926.51(f)(1) changes that fast. If your crew handles coatings, herbicides or insecticides, you need washing facilities on site, and hand sanitizer alone doesn't satisfy 29 CFR 1910.141(d)(2), which calls for soap and towels or a hand-drying device. That citation technically governs general industry workplaces rather than construction, but plenty of Des Plaines contractors run both types of site and it's worth knowing the difference. A handwashing station rental or portable sink rental covers the gap cheaply compared to the cost of a citation. Our handwashing requirements page breaks down which OSHA section applies to which kind of site, construction versus general industry versus agricultural.
Some crews try to skate by with a hand sanitizer station rental instead. Fine as a supplement, not a substitute, when the paint-and-chemical trigger is in play.
Illinois sites follow federal OSHA, not Cal OSHA, so the California-specific standard doesn't apply in Des Plaines. Cal OSHA's portable toilet requirements for construction are stricter in some areas, closer unit spacing and shorter service intervals among them, but that's a California-only framework. If you're managing sites in both states, don't assume the ratios line up. Illinois contractors searching cal osha portable toilet requirements or cal osha portable toilet requirements construction should note that framework stays in California; Illinois contractors work from OSHA 1926.51(c) alone, and ANSI/PSAI Z4.3 sets the baseline service interval most rental companies build their route schedules around: one visit per week for up to 10 users over a 40 hour week. Busier sites need standard units serviced more often, which is why we quote service frequency separately from the unit itself.
For pricing across daily, weekly and monthly terms, our porta potty rental cost and monthly porta potty rental pages break it down. A standard unit typically runs in this range:
| duration | typical range |
|---|---|
| day | $100 - $350 |
| week | $130 - $500 |
| month | $125 - $325 |
Sites needing an accessible unit should check ADA accessible porta potty and ADA Standards 213.2, which requires at least one accessible unit in any cluster, 5 percent minimum once the cluster grows.
Sometimes, depending on where the unit sits. Placement on a public sidewalk or in the right of way needs confirming with the city before delivery. Private property jobsites usually don't need one. Check our porta potty permit requirements page or call before you commit to a spot.
Once you pass 20 workers, OSHA 1926.51(c) requires 1 toilet seat and 1 urinal per 40 additional workers. A 25-person crew technically needs a second facility. Most contractors round up early rather than track the exact threshold mid-project.
No, not automatically. It's required specifically when workers apply paints, coatings, herbicides or insecticides, per OSHA 1926.51(f)(1). A dry framing or drywall crew without chemical exposure typically doesn't trigger that rule.
Depends on the job scope, not the toilet count. Our 10 yard dumpster rental and 20 yard dumpster rental pages cover common construction sizes, and dumpster sizes and dimensions compares them side by side.
Yes. Des Plaines contractors often order both together for one delivery window, the same way a crew searching portable toilet rental oshawa or storage container rental oshawa up north would bundle theirs. See storage container rental or 20ft storage container for options, and bundle the request when you request a quote.
