Every job site needs toilets, and OSHA 1926.51(c) sets the ratio: one toilet for 20 workers or fewer, more above that. Evanston Porta Pros builds out full site packages for general contractors, from single porta johns to fenced compounds with dumpsters, storage and power on the same delivery run.
A standard job site package starts with the standard porta potty rental, which runs 44 by 48 inches on the ground and stands about 92 inches tall, built around a 60 to 70 gallon holding tank. That covers a small crew fine. Add crew size and the math changes fast, which is why we size against OSHA 1926.51(c): one unit per 20 workers, then a toilet seat and urinal per 40 once you cross that line. Most Evanston job sites also need a roll-off dumpster rental for debris, and OSHA 1926.25 expects scrap cleared from work areas as a matter of course, so the dumpster isn't optional dressing, it's part of staying compliant. Bigger sites add a temporary fence rental around the perimeter and a light tower rental for early starts or winter dusk, since OSHA 1926.56(a) sets minimum lighting for active construction areas. If your crew is doing paint, coatings or chemical work, OSHA 1926.51(f)(1) kicks in and washing facilities become required, not optional, so a handwashing station rental belongs on the delivery ticket alongside the toilets. We quote all of this as one package so you don't juggle four vendors on one Evanston address.

Start with your peak headcount, not your average. OSHA 1926.51(c) requires one toilet facility for crews of 20 or fewer, then a toilet seat and urinal for every 40 workers above that, scaling again at 200 workers to one seat and urinal per 50. A 15-person crew needs one unit. A 60-person crew needs closer to three. Run your own numbers with the how many porta potties do I need guide, or read the ratio table straight from OSHA portable toilet requirements. Rental duration matters too: a short punch-list job in Evanston might only need a porta potty rental per day, while a multi-month build calls for a monthly porta potty rental instead, and the per-unit cost drops the longer you commit. If the crew includes anyone with a mobility limitation, ADA Standards section 213.2 requires at least one accessible unit in any cluster of portable toilets, never fewer than one regardless of cluster size. We stock the ADA accessible porta potty built around a 60 inch turning circle per ADA 304.3.1 for exactly that requirement.
Yes. OSHA 1926.51(c) is a construction-specific rule and it applies regardless of state, whether you're running a crew in Evanston or fielding a construction portable toilet rental near Texas or California job site under Cal/OSHA's parallel standard. The federal ratio is one unit per 20 workers at minimum. Potable water is a separate requirement under OSHA 1926.51(a)(1), and if your crew handles paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities on top of the toilets, not instead of them. General industry sites, as opposed to active construction, fall under 29 CFR 1910.141(c)(1)(i) instead, with its own ratio table. We deliver units already positioned to meet spacing and ground stability expectations under ADA 302.1 where accessible units are required. Placement in the public right of way in Evanston needs confirming with the city before delivery day, since that call sits with the municipality, not with us. Our porta potty placement guide covers ground conditions and clearance in more depth, and the porta potty permit requirements page walks through what to check before your delivery date.
Pricing depends on unit type, crew size and rental length, and longer terms bring the daily rate down even though the total climbs.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $200-$240 | - |
| deluxe | $85-$1,200 | $150-$290 | - |
A delivery fee typically runs $100 to $500 for a single trip, less for weekly or monthly accounts. Most Evanston contractors land on the standard unit at weekly or monthly rates once the job runs past a couple of weeks; short punch-list work usually books daily instead. Full detail lives on the porta potty rental cost page, and if you're comparing against a residential job, home renovation porta potty pricing runs a similar band. For dumpster costs on the same site, see dumpster rental cost.
It depends on the scope. Framing debris and roofing tear-off fill a 30 yard dumpster rental fast, while a kitchen remodel or small addition usually fits a 20 yard dumpster rental. Check dumpster sizes and dimensions before booking.
Yes. A storage container rental keeps tools and materials locked up overnight, and a 20ft storage container covers most single-crew jobs. Larger builds often add a mobile office trailer rental for the same delivery.
Possibly, depending on placement. Anything sitting in the street or right of way needs confirming with the city directly; we do not guess at ordinance numbers. See dumpster permit requirements before delivery.
Weekly service is the baseline under ANSI/PSAI Z4.3 for up to 10 users across a 40 hour week. Busier sites need more frequent visits. Details are on how often are porta potties cleaned.
It's a rush delivery when a unit fails or a crew shows up unplanned, usually same-day. We run emergency porta potty rental across Evanston and can typically turn a delivery around within the day.
