OSHA requires 1 toilet for every 20 workers on a construction site, per 1926.51(c). That number changes as your crew grows. Oak Park Porta Pros sets up compliant portable toilet rental counts for job sites across Oak Park, whether you have 8 workers or 80.
The rule is 1926.51(c), and it scales in steps. For 20 workers or fewer, you need 1 toilet. From 20 up to 200 workers, add 1 toilet seat and 1 urinal for every 40 workers. Past 200 workers, that ratio drops to 1 seat and 1 urinal per 50 workers. A general contractor running a 35-person crew in Oak Park needs at least 2 units under that math. If you're unsure where your headcount lands, how many porta potties do I need walks through the math with real examples, and our OSHA portable toilet requirements breakdown ties directly back to the same table. Cal OSHA portable toilet requirements construction rules mirror this federal standard closely, though California sites should confirm with their state plan directly. For standard porta potty rental in Oak Park, we size the order to your daily headcount, not just square footage.
OSHA does not publish a fixed foot-distance rule for portable toilet placement on construction sites. What it does require is potable water under 1926.51(a)(1) and handwashing after work with paints, coatings, herbicides or insecticides under 1926.51(f)(1). Placement in Oak Park's public right of way needs confirming with the city before delivery day, since that is not something OSHA governs. Our porta potty placement guide covers ground clearance, slope and access considerations that come up on real sites. If your project sits near a residential lot line in Oak Park, our crew checks setback and drainage before we set a unit down. For sites needing ADA access, ADA accessible porta potty units meet a different set of federal specs entirely, covered below.
Not automatically, but many public-facing and mixed-use sites need at least one. ADA Standards section 213.2 requires that where portable toilets are clustered, at least 5 percent must be accessible, with a minimum of one unit regardless of cluster size. That accessible unit needs a 60 inch turning circle under section 304.3.1, a 32 inch clear door opening under 404.2.3, and an approach route at least 36 inches wide under 403.5.1. Our ADA accessible porta potty rentals meet those dimensions, and pricing runs in the range below. Projects in Oak Park working near Maywood, about 3.4 miles west, or Elmwood Park, 4.0 miles northwest, often mix standard and ADA units on the same delivery. Our ADA restroom requirements page details reach ranges and operable-part rules under sections 308.2.1 and 309.4 if your site needs to document compliance.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | -- | -- |
| deluxe | $85-$1200 | $150-$290 | -- |
Weekend rates for ADA units run $199 to $300 as a flat short-term rate, and weekly rates run $120 to $240 when booked as a standalone weekly order rather than stacked daily, separate from the daily figures above. For longer builds, monthly porta potty rental in Oak Park usually costs less per day than short-term orders, and our porta potty rental cost page breaks down every variable that moves the price.
Yes, and this trips people up constantly. 1926.51(f)(1) only applies where crews are applying paints, coatings, herbicides or insecticides, or working around similar contaminants. It is not a blanket handwashing mandate for every job site. Under 29 CFR 1910.141(d)(2), where washing facilities are required, they must include soap and towels or a hand-drying device. Hand sanitizer alone does not satisfy that rule. Our handwashing station rental units in Oak Park include soap and paper towel dispensers standard, and handwashing requirements covers which job types actually trigger the federal rule. Farm operations fall under a different standard entirely: 1928.110 requires one field sanitation facility per 20 hand-labor employees, reachable within a quarter mile. If your Oak Park site also generates debris, pair your sanitation order with a roll-off dumpster rental or check dumpster permit requirements before delivery, since housekeeping rules under 1926.25 require cleared work areas too. Sites running heavy equipment at night should also review light tower rental against the illumination minimums in 1926.56(a).
Storage needs often show up alongside sanitation on a jobsite bid. If you're pricing a storage container rental alongside your toilet count, note that monthly storage runs $100 to $250 depending on container size, separate from the portable toilet numbers above.
Under 1926.51(c), a crew of 20 or fewer needs exactly 1 toilet. Once you cross 20 workers, OSHA requires 1 additional seat and urinal per 40 workers. Our how many porta potties do I need guide runs the numbers for larger crews and mixed shifts.
No published distance rule exists under 1926.51(c). OSHA focuses on ratio, not footage. Placement on Oak Park sites, especially in the right of way, still needs city confirmation separate from any OSHA requirement. Check our porta potty permit requirements page for what to ask the city.
Only where units are clustered together. ADA Standards 213.2 sets a minimum of 5 percent accessible, never fewer than one. A single isolated unit on a small site typically doesn't trigger the cluster rule, but confirm with your project owner.
Cal OSHA portable toilet requirements construction rules closely track the federal 1926.51(c) ratios. California sites operate under their own state plan, so confirm specifics with Cal OSHA directly rather than assuming the federal table applies word for word.
Yes. Standalone units work fine for many Oak Park sites. Our portable sink rental and hand sanitizer station rental options cover different budget levels, and neither requires ordering a full restroom trailer rental.
