Placement comes down to four things: a level pad at least 44 by 48 inches, 36 inches of clear path per ADA Standards 403.5.1, no low branches near the 92 inch unit height, and a spot the pump truck can reach without crossing a curb. Get those right and the rest of the job goes smoothly.
Pick flat ground first. A standard unit needs about 44 by 48 inches of footprint and stands roughly 92 inches tall, so check for low wires or tree limbs before the truck shows up. Des Plaines properties with alley access often place units near the alley so the service truck avoids the front lawn. If you are working from the placement rules on our porta potty rental cost page or comparing a standard porta potty rental against a deluxe flushable porta potty, the footprint math is the same either way. Keep the unit away from storm drains and slope the ground so nothing pools underneath. On construction sites, pair placement with your temporary fence rental layout so foot traffic does not cut across the fence line to reach the toilet. If you are running a handwashing station rental alongside it, put both units together near the crew's break area, not scattered across the lot.
An ADA-compliant unit needs a 60 inch turning circle inside or beside it, per ADA Standards 304.3.1, plus a door opening of at least 32 inches under ADA Standards 404.2.3. When you cluster several units, ADA Standards 213.2 requires at least 5 percent to be accessible, and never fewer than one. That means a Des Plaines event with ten standard porta potty rental units still needs at least one ADA accessible porta potty on a firm, stable surface, per ADA Standards 302.1. Reach controls should sit within 48 inches high and 15 inches low, per ADA Standards 308.2.1, and door hardware should take no more than 5 pounds of force to operate under ADA Standards 309.4. If a ramp is needed to reach the pad, keep the slope at 1:12 or flatter per ADA Standards 405.2. Our ADA restroom requirements page walks through layout examples in more detail.
Permit rules for placing a dumpster or portable restroom in the public right of way vary by situation, and dumpster placement permit cost is not something we can quote without checking with the City of Des Plaines directly. If your roll-off or restroom trailer sits entirely on private property, you likely skip that step, but street or parkway placement usually needs sign-off first. Confirm with the city before delivery day rather than guessing. Our dumpster permit requirements and porta potty permit requirements pages cover what to ask when you call. A roll-off delivery also needs about 60 feet of straight clearance behind the truck, so measure your driveway or lot entrance before the driver arrives. That clearance number matters more in tight urban lots than it does in an open construction yard, and it applies whether you are ordering a 10 yard dumpster rental or a 30 yard dumpster rental. Check dumpster sizes and dimensions if you are unsure which size fits your access.
Worker counts drive both toilet numbers and placement. OSHA 1926.51(c) sets the baseline: one toilet facility for 20 workers or fewer, then one seat and one urinal per 40 workers up to 200, and one per 50 beyond that. OSHA 1926.51(a)(1) also requires an adequate supply of potable water at every place of employment, which is why crews often pair toilets with a portable sink rental nearby. If your crew is painting, coating, or applying herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that contaminant exposure specifically, and towels or soap must be provided under 29 CFR 1910.141(d)(2), since hand sanitizer alone does not satisfy that rule. Farm crews doing hand labor fall under OSHA 1928.110 instead, which calls for one facility per 20 employees within a quarter mile walk. For exact counts by crew size, use how many porta potties do I need or review OSHA portable toilet requirements before you finalize placement.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$500 | n/a |
| deluxe | $85-$1200 | $150-$290 | n/a |
Weekend rates run separately from day and week pricing; a standard unit over a weekend typically falls between $125 and $400, which matters if you are placing units for a Saturday event rather than a full week-long job. Compare durations on our porta potty rental per day and monthly porta potty rental pages before you commit to a term.
Beyond toilets, placement thinking carries over to other equipment. A storage container rental or mobile office trailer rental needs the same flat, accessible pad, and if your office trailer's entry door has taken damage, mobile office trailer replacement doors are a separate line item worth asking about before renewal. Septic work follows its own logic: a residential tank is typically pumped every 3 to 5 years depending on tank size and household size, and a grease interceptor gets pumped once fats, oils, grease and solids reach 25 percent of liquid depth. If you are researching septic pumping service outside Des Plaines, note that a placerville septic pumping service company would follow the same interval guidance, just under a different jurisdiction. Locally, our septic pumping service and how often to pump a septic tank pages cover the specifics. For handwashing equipment upkeep, ozark river portable sink replacement parts come up often enough that it is worth checking part compatibility before you order a unit for a multi-week rental. Mount Prospect sits 3.4 miles northwest of Des Plaines and Park Ridge 4.6 miles southeast, so crews working across both towns can usually consolidate delivery runs into one trip. See service areas for coverage across Elk Grove Village and Glenview as well.
Keep it close enough for convenience but clear of doorways, windows and air intakes. A few feet of separation from the structure and a stable, level pad handle most situations. Avoid placing units directly beneath windows that open.
Yes, if the gravel is compacted and level. Loose or sloped gravel risks tipping, especially with a 60 to 70 gallon holding tank adding weight. A plywood pad under the unit helps distribute load on soft surfaces.
Not directly, but harder-to-reach placement can slow the service truck down. ANSI/PSAI Z4.3 sets a baseline of one visit per week for up to 10 users over a 40 hour week, so easy truck access keeps that schedule on track.
Neighbor complaints and possible code issues, depending on setback rules where you live in Des Plaines. Check with the city before finalizing placement near a shared line, particularly for multi-week construction rentals.
Short distances on the same flat surface, yes, but the tank gets heavy fast once used. For anything beyond a few feet, ask Des Plaines Porta Pros to reposition it during a service visit instead.
