How many units do I need?
Start with headcount, not guesswork. OSHA 1926.51(c)(1) sets the construction ratio: one toilet for 20 or fewer workers, then one toilet seat and one urinal per 40 workers once you pass 20, and per 50 once you hit 200 or more. For non-construction workplaces, use 1910.141(c)(1)(i) instead. Events run differently. A wedding or a block party in Saint Clair Shores works better off a per-guest count than a labor ratio, and our event restroom rental page walks through both math paths. Farm crews fall under 1928.110, which asks for one facility per 20 hand-labor employees within a quarter mile walk. If the number still feels fuzzy, our sizing guide breaks it down by job type, and the full ratio table lives on OSHA portable toilet requirements. Renting one unit short is the single most common mistake we see on job sites here.
What size and access does the site need?
A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your gate and path before delivery day, not after. If you're adding a restroom trailer rental instead, the truck needs real room to maneuver, and any roll-off delivery on the same site needs about 60 feet of straight clearance behind the truck. Ground has to be level and firm. ADA units matter here too: ADA Standards 304.3.1 calls for a 60 inch turning circle, 404.2.3 sets a 32 inch minimum door opening, and 403.5.1 requires a 36 inch clear route to reach it. If units get clustered together, ADA Standards 213.2 requires at least 5 percent to be accessible, never fewer than one. Check our ADA accessible porta potty page for specifics, and the placement guide covers slope, overhead lines and setback from structures.
When should I schedule delivery and service?
Book 10 to 14 days ahead for anything predictable, sooner for holiday weekends. Once units are on site, ANSI/PSAI Z4.3 sets the baseline service interval at one visit per week for up to 10 users across a 40 hour week, so a busy crew or a weekend festival needs more frequent pumping than that floor number. Multi-week jobs should lock in a standing schedule rather than calling each time; see monthly porta potty rental for how that pricing works. If you're weighing day rate against a longer term, porta potty rental cost and porta potty rental per day lay out both. Short jobs, like a one-day driveway pour or a Saturday open house in Saint Clair Shores, usually run on a weekend rate instead of a full week, which is worth asking about before you commit.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| deluxe | $85-$1200 | $150-$290 | -- |
| ada | $200-$400 | $240-$300 | -- |
A standard unit's holding tank runs 60 to 70 gallons, which is part of what drives service frequency on longer rentals. If your project also needs waste removal, pair the toilet order with a roll-off dumpster rental or check dumpster rental cost so both trucks can schedule the same delivery window.
Do I need a permit for placement in Saint Clair Shores?
Placement in the public right of way needs confirming with the city before delivery, since permit rules and fees are not something we publish without checking them first. Sidewalk or street placement almost always needs sign-off; a driveway or private lot usually does not, but confirm before the truck rolls. Our porta potty permit requirements page explains what to ask the city and when. This step gets skipped more than any other item on this checklist, and it is the one that stops a delivery cold.
Beyond permits, plan for handwashing. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at washing stations; hand sanitizer alone does not meet it. If your crew works with paints, coatings, herbicides or insecticides, 1926.51(f)(1) requires washing facilities for that contact specifically, not as a general rule. Pair your toilets with a handwashing station rental or a portable sink rental to cover both. OSHA 1926.51(a)(1) also requires an adequate supply of potable water at every place of employment, worth checking against your water tank capacity before the job starts. If the site runs a septic system feeding a temporary setup, know that a typical residential tank gets pumped every 3 to 5 years depending on size and household load, covered in more depth on how often to pump a septic tank.
For jobs mixing several services, storage, fencing and sanitation together, construction site services and temporary fence rental round out the checklist, and Saint Clair Shores Porta Pros delivers to Roseville 3.8 miles northwest and Eastpointe 4.3 miles southwest as well.
How far in advance should I book a porta potty?
Ten to 14 days out covers most jobs. Holiday weekends and graduation season fill trucks faster, so call sooner if your date falls near one. Saint Clair Shores event bookings in peak season sometimes need three weeks of lead time to guarantee a specific unit type.
Can I place a porta potty on the street?
Only with the city's sign-off. Placement in the public right of way needs confirming with Saint Clair Shores before delivery. A driveway or private lot rarely needs the same review, but always ask first.
How many toilets does OSHA require per worker?
1926.51(c)(1) sets one toilet for 20 or fewer construction workers, then one toilet and one urinal per 40 workers above that, and per 50 once the crew reaches 200 or more.
Does a hand sanitizer station meet OSHA rules?
No. 29 CFR 1910.141(d)(2) requires soap plus towels or a hand-drying device. Sanitizer alone does not satisfy that standard, so pair any unit with a proper handwashing setup.
What size is a standard porta potty?
About 44 by 48 inches on the ground and 92 inches tall, with a 60 to 70 gallon holding tank. Measure gates and paths against those numbers before delivery day.
