What Does a Construction Site Need for Sanitation?
Start with the toilet math. OSHA 1926.51(c) sets the ratio: one unit for 20 workers or fewer, and one toilet seat plus one urinal per 40 workers once you cross 20, dropping to one per 50 workers at 200 or more. Below that, you're exposed if an inspector shows up. A standard porta potty rental covers most crews just fine, with a 60 to 70 gallon holding tank on a unit that's about 44 by 48 inches on the ground and 92 inches tall. Bigger crew, tighter budget? Run the numbers with our how many porta potties do I need guide before you order. Water matters too: OSHA 1926.51(a)(1) requires an adequate supply of potable water at every job site, which is why a lot of Aurora contractors pair toilets with a handwashing station rental or a portable sink rental rather than relying on sanitizer alone, since 29 CFR 1910.141(d)(2) calls for soap and towels or a drying device, not sanitizer as a substitute.
How Much Does Portable Toilet Rental Cost for Construction Sites?
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ADA unit | $200 - $400 | $240 - $400 | -- |
| dumpster | $51 - $112 | $426 - $778 | $500 - $778 |
Monthly is the move for anything past a few weeks, since a standard unit rented by the day adds up fast on a job that runs all season. Delivery runs separately, typically $100 to $500 for a one-time trip depending on distance and access. Full breakdown, with monthly discounts explained, lives on our monthly porta potty rental page, and general pricing logic, including portable toilet rental for construction sites cost, is on porta potty rental cost. If you just need day-rate numbers for a short pour or punch-list job, see porta potty rental per day. Crews handling paint, coatings, herbicides, or insecticides trigger a separate rule: OSHA 1926.51(f)(1) requires washing facilities specifically for that contaminant exposure, on top of the general toilet count.
Do I Need an ADA-Accessible Unit on a Construction Site?
Yes, if the site has public-facing workers or visitors who might need one, and ADA Standards 213.2 requires at least 5 percent of clustered single-user units be accessible, with a minimum of one no matter how small the cluster. An ADA accessible porta potty needs a 60 inch turning circle per ADA 304.3.1 and a clear door opening of at least 32 inches under ADA 404.2.3. Most general contractors in Aurora order one ADA unit alongside standard units even on crews well under the threshold, just to keep inspectors and subs happy. Full detail on the standard, plus how it interacts with local project types, is on ADA restroom requirements and osha portable toilet requirements construction rules at OSHA portable toilet requirements. If your site also needs debris control, pair the toilet order with a construction dumpster rental, since OSHA 1926.25 requires scrap and debris cleared from work areas and a 20 or 30 yard box handles most residential-scale jobs without a second delivery trip.
What Else Does a Job Site Need Besides Toilets?
Fencing, lighting, power, and a dumpster round out most permit packages. A temporary fence rental keeps the public off an active site, and barricades used for that purpose still need to conform to ANSI D6.1 under OSHA 1926.202. Night pours or winter jobs in Aurora often need a light tower rental to meet the illumination minimums in OSHA 1926.56(a). Running saws, pumps, or trailers off generator power? Ask about a temporary power pole and make sure any temporary circuits have GFCI protection per OSHA 1926.404(b)(1)(ii). For roll-off needs, roll-off dumpster rental covers general debris, while dumpster weight limits and what cannot go in a dumpster answer the two questions that generate the most overage fees. Delivery trucks need roughly 60 feet of straight clearance behind them to place a roll-off box, so flag tight alleys or narrow driveways when you book. If the crew is bunking on site or the job needs lockable equipment storage, a storage container rental or mobile office trailer rental solves both in one drop.

How many portable toilets does OSHA require on a construction site?
One toilet for 20 workers or fewer, per OSHA 1926.51(c). Above 20 workers, it's one toilet seat and one urinal per 40 workers, dropping to one per 50 once the crew hits 200 or more. Field crews and farm labor fall under a separate rule, OSHA 1928.110.

How far in advance should I book porta potties for a job site?
Book as early as you can once you have a start date, especially for large crews or ADA units, which run in shorter supply. Short notice still works for most single-unit or small-crew orders; call and ask about emergency porta potty rental if the job starts this week.
Can I rent just one portable toilet for a small renovation job?
Yes. A single standard unit covers most small crews under the 20-worker threshold in OSHA 1926.51(c). See home renovation porta potty for sizing on smaller residential jobs, or porta john rental for basic single-unit pricing.
Do construction sites need a permit for a portable toilet?
Placement in a right-of-way or on a public sidewalk usually needs city sign-off, and that requirement varies by property and street. Confirm placement rules with the City of Aurora before delivery; see porta potty permit requirements for the questions to ask.
