How many porta potties do I need for my site?
Start with headcount, not guesswork. OSHA 1926.51(c)(1) sets the baseline for construction sites: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass 20, and per 50 workers at 200 or more. If you run a farm crew instead, OSHA 1928.110 asks for one facility per 20 hand-labor employees, reachable within a quarter mile. Event organizers should size differently, by headcount and hours, not payroll; see the porta potty rental checklist guide on how many you need for that math. Whatever the site, add one accessible unit under ADA Standards 213.2, which requires at least 5 percent of a cluster be accessible and never fewer than one. Cross-check your count against the OSHA portable toilet requirements page before you finalize an order, especially on multi-contractor sites where headcounts shift week to week.
Where should units be placed on site?
Placement decides how well the rest of the checklist works. A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your spot before delivery day, not after the truck arrives. Keep an ADA unit on a stable, firm, slip-resistant surface per ADA Standards 302.1, with a 60 inch turning circle nearby per ADA Standards 304.3.1 and a clear route at least 36 inches wide per ADA Standards 403.5.1. Door openings need to clear 32 inches under ADA Standards 404.2.3, and every operable latch should work with one hand and under 5 pounds of force per ADA Standards 309.4. Delivery trucks need about 60 feet of straight clearance behind them, which matters on tight Gary lots near Hobart, 8.5 miles southeast, or Merrillville, 10.8 miles south, where alley access can be narrow. Full guidance lives on the porta potty placement guide, and if the unit sits in the public right of way, that placement still needs confirming with the City of Gary directly, since right-of-way rules were not verified for this page.

Do I need a permit for a portable toilet in Gary?
Maybe, and it depends on where the unit sits. Placement on private property is usually simple, but units on a sidewalk, street, or any public right of way in Gary typically need sign-off from the city, and that requirement was not verified for this page, so confirm it before delivery. The porta potty permit requirements page walks through what to ask the city clerk's office. Dumpsters carry their own separate permit questions in Gary, covered on the dumpster permit requirements page, so do not assume one permit covers both a toilet and a roll-off box on the same job. If your event or build also needs temporary fence rental or a light tower at the perimeter, ask about those separately too, since barricades on active job sites fall under OSHA 1926.202 and ANSI D6.1 for construction crews, not municipal permitting.

What should I check before the delivery truck shows up?
Confirm four things: ground clearance, service interval, water source, and duration. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users across a 40 hour week, so a small crew on a short job may only need one pump-out, while a packed event needs more frequent service. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which matters if you are also renting a handwashing station or portable sink alongside the toilets. If your crew is spraying paint, coatings, herbicides, or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that specific work, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand dryer at that station, not just sanitizer. Decide your rental length now, since day, week, and month rates differ. Compare durations on the porta potty rental cost page or the monthly porta potty rental page before you commit.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $200-$240 | not offered |
| deluxe | $85-$1200 | $150-$290 | not offered |
Weekend rates run separately: a standard unit weekend rental typically lands between $125 and $400, and an ADA weekend unit runs $199 to $300. For side-by-side detail, see porta potty rental per day and the general portable toilet rental page, which is this checklist's cluster pillar.
Should I rent a restroom trailer instead of a standard unit?
Rent a trailer for weddings, staff events, or any job where flush fixtures matter more than headcount math. A restroom trailer rental or 2 stall restroom trailer suits smaller crews, while an 8 stall restroom trailer fits larger festivals. Standard units still win on tight budgets and simple job sites.
How far in advance should I book in Gary?
Book 10 to 14 days ahead for standard jobs, longer for weekend events near Portage, 12.5 miles east, or Schererville, 13.3 miles southwest, where trucks may be routed through multiple stops. Rush orders happen, but confirmed placement and permit answers take time.
Do I need a separate handwashing station?
Yes, if your crew works with paint, coatings, or chemicals under OSHA 1926.51(f)(1), or if you want handwashing independent of the toilet units. A hand sanitizer station is not a substitute for soap and water under 29 CFR 1910.141(d)(2).
What cannot go in a job site dumpster?
Certain materials are barred by weight and hazard rules covered on the what cannot go in a dumpster page and the dumpster weight limits page. Check both before loading a roll-off dumpster.
Does winter weather change the checklist?
Yes. Cold slows service routes and can affect tank function, so review the porta potty in winter guide before a Gary winter job, and plan service visits with extra lead time.
