How many units do I need?
Start with headcount and hours, not guesswork. OSHA 1926.51(c) sets construction sanitation ratios: one toilet for 20 or fewer workers, then one toilet seat and one urinal per 40 workers once you pass 20, and one seat and one urinal per 50 workers at 200 or more. Berwyn Porta Pros uses that table as the floor for construction site services, then adds units for multi-shift jobs or spread-out sites. Events run differently. There's no fixed OSHA formula for a wedding or festival, so event restroom rental planning leans on guest count and bar service instead. Use the how many porta potties do I need guide to run your own numbers before you call. If you're still unsure, request a quote and describe the job; a same-day estimate beats a unit sitting unused for a week.
What type of unit fits the job?
A standard porta potty rental covers most construction and casual outdoor work: about 44 by 48 inches on the ground, 92 inches tall, with a 60 to 70 gallon holding tank. For weddings or corporate events, a deluxe flushable porta potty or a full restroom trailer rental reads better next to a tent or a venue entrance. Bigger crews need more stalls: a 2 stall restroom trailer works for smaller gatherings, while an 8 stall restroom trailer handles a fair-sized crowd. Any site with public foot traffic should also budget an accessible unit. ADA Standards section 213.2 requires that at least 5 percent of clustered single-user toilets be accessible, with never fewer than one. Our ADA accessible porta potty units meet the section 404.2.3 minimum 32 inch clear door opening and the section 304.3.1 60 inch turning circle, so wheelchair users aren't stuck outside.
Where should the unit go on site?
Placement decides how well the whole rental works. Trucks need about 60 feet of straight clearance behind them for delivery, so tight alleys or packed lots in Berwyn need a walkthrough first. Keep units on level, stable ground; ADA Standards section 302.1 calls for firm, slip-resistant surfaces, which matters just as much on a muddy spring jobsite as it does for an accessible unit. Leave a 36 inch clear path to the door, matching ADA Standards section 403.5.1 for accessible routes, and don't block it with equipment, saw horses or debris piles that violate the housekeeping standard in OSHA 1926.25. If the unit sits anywhere near the public right of way or a sidewalk, placement needs confirming with the City of Berwyn before delivery, since we're not citing a specific ordinance here. Full guidance lives on the porta potty placement guide and porta potty permit requirements pages, and permit questions belong on the dumpster permit requirements page if you're renting a roll-off alongside the toilets.
Does the unit need handwashing or servicing on a schedule?
Yes, on both counts, and they're separate requirements. General sanitation and adequate potable water fall under OSHA 1926.51(a)(1) and 1926.51(c). If crews are applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in specifically for washing off those contaminants, which is different from routine handwashing. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations; hand sanitizer alone doesn't satisfy it. Add a handwashing station rental or a portable sink rental next to any toilet cluster, especially on food-service or paint jobs. On service intervals, ANSI/PSAI Z4.3 sets a baseline of one visit per week for up to 10 users across a 40 hour week, though busier sites need more frequent stops. Check the how often are porta potties cleaned page for what a service visit actually includes.
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| deluxe | $85 - $1200 | $150 - $290 | - |
| ada | $200 - $400 | $200 - $500 | - |
Delivery runs $100 to $500 a day depending on distance and access, separate from the unit rate. See the porta potty rental cost and porta potty rental per day pages for a fuller breakdown, or monthly porta potty rental if the job runs long. Berwyn sits close enough to several towns we already serve, including Forest Park 3.0 miles northwest and Brookfield 3.7 miles southwest, that delivery timing rarely slips.
What if I need a unit on short notice?
Same-day and next-day delivery is often possible if a standard unit is available nearby. Call Berwyn Porta Pros directly rather than waiting on a web form. The emergency porta potty rental page covers what qualifies as urgent and how fast trucks can typically respond in Berwyn.
Do I need a permit for a porta potty in my driveway?
Private property placement usually needs no permit, but sidewalk or street placement does need city confirmation. Check the porta potty permit requirements page first, then call the city if your unit sits anywhere near a public right of way.
How many toilets does OSHA require for a small crew?
For 20 workers or fewer, OSHA 1926.51(c) requires one toilet facility. That number climbs in steps as crew size grows. See OSHA portable toilet requirements for the full ratio table applied to your headcount.
Can I rent just one unit for a weekend event?
Yes. Weekend rentals are common for backyard parties and small gatherings, priced separately from daily or weekly rates. A single standard or deluxe unit often covers events under roughly 50 guests; check event restroom rental for sizing help.
Will winter weather affect my rental?
Cold weather changes tank chemistry and servicing needs, but units still function through Illinois winters. The porta potty in winter page covers freeze prevention and servicing adjustments specific to the season.
