How Many Porta Potties Do I Need for a Job Site?
Start with the headcount, then apply OSHA 1926.51(c)(1): 1 toilet seat for 20 workers or fewer, 1 toilet seat plus 1 urinal per 40 workers once you pass 20, and 1 seat plus 1 urinal per 50 workers at 200 or more. A 15-person crew in Garden City, 7.5 miles north of Savannah, needs one standard unit. A 60-person crew needs two seats and a urinal, or the trailer equivalent. Run the math with our how many porta potties do i need guide before you order, because under-counting is the mistake that gets flagged first. Most Savannah crews rent standard porta potty rental units for this, since a 60 to 70 gallon tank on a 44 by 48 inch footprint handles daily use without extra service calls. If your crew works a stretch with no water hookup, OSHA 1926.51(a)(1) still requires potable water on site, separate from toilet count. Bigger sites sometimes upgrade to a restroom trailer rental instead of stacking single units, especially past the 100-worker mark.
Is Cal OSHA Different from Federal OSHA for Portable Toilets?
Cal OSHA portable toilet requirements construction rules mirror the federal ratio in 1926.51(c)(1) for construction but add stricter field sanitation language in some agricultural contexts. Georgia follows federal OSHA, not the California state plan, so Savannah contractors work off the same 1-per-20 ratio without a separate state overlay. That keeps planning simpler: pull the ratio table, count heads, order units. Farms working seasonal labor near Richmond Hill, 19.0 miles southwest, fall under a related but distinct rule, OSHA 1928.110, which sets field sanitation at 1 facility per 20 workers within a quarter mile walk. That is a farm-labor standard, not a general construction one, so check which category your site fits before ordering. Our farm and agricultural restrooms page breaks that distinction down further. General industry sites, like a warehouse buildout instead of an outdoor jobsite, fall under 1910.141(c)(1)(i) instead of the construction table, and the ratios differ.
What Are OSHA Portable Toilet Distance Requirements?
OSHA does not set a fixed foot distance from work areas to toilets in 1926.51(c)(1); it sets ratios by headcount, and placement is left to reasonable access. That said, ADA Standards 403.5.1 require a 36 inch clear path to any accessible unit, and 405.2 caps ramp slope at 1:12 if the ground is not level. Practically, most Savannah site supervisors place units within a short walk of the active work zone, then adjust as the job moves. Our porta potty placement guide covers ground conditions, delivery clearance, and service access. A roll-off or restroom trailer delivery needs about 60 feet of straight clearance behind the truck, which matters on tight downtown Savannah lots near historic squares. If you are clustering multiple single-user units, ADA Standards 213.2 requires at least 5 percent to be accessible, never fewer than one. Check our ada accessible porta potty page for unit specs, including the 60 inch turning circle required under ADA 304.3.1.
Do OSHA Rules Require Handwashing at Every Site?
Not automatically. General sanitation under 1926.51(c) governs toilets, but handwashing is required specifically where employees apply paints, coatings, herbicides or insecticides, under 1926.51(f)(1). That is a contaminant-specific rule, not a blanket mandate for every construction site. If your crew is doing general framing or excavation with no chemical exposure, that clause does not apply, though most supervisors add handwashing station rental anyway for practical hygiene. Where it does apply, 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device; hand sanitizer alone does not satisfy it. A portable sink rental unit meets that standard better than a sanitizer stand alone. Sites near Henderson, 9.7 miles west of Savannah, doing exterior painting or pesticide work should budget for this before the crew arrives, not mid-job. Our handwashing requirements page walks through which trades trigger the rule.
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| standard | week | $200 |
| standard | month | $200 |
| ada | week | $185 |
| delivery_fee | day | $150 |
Pricing varies by site access and rental length; see porta potty rental cost or monthly porta potty rental for a fuller breakdown. Savannah Porta Pros delivers across the metro, including jobs near Montgomery, 12.7 miles southeast, and can quote exact counts once you send crew size and duration through request a quote. We are not portable toilet rental oshawa or a storage container rental oshawa outfit; Savannah Porta Pros works Savannah and the towns listed above, and if you need job-site storage alongside toilets, check storage container rental.
How many porta potties does OSHA require for 50 workers?
For 50 workers, OSHA 1926.51(c)(1) requires 1 toilet seat plus 1 urinal, since that count falls in the 20-to-under-200 bracket. Some supervisors round up to two full units for faster turnover during breaks. Check our osha portable toilet requirements ratio table or talk to Savannah Porta Pros directly for a headcount-based quote.
Does OSHA require ADA-compliant porta potties on every site?
Not every site, but where units are clustered, ADA Standards 213.2 requires at least 5 percent to be accessible, never fewer than one unit. A single-unit site with a worker needing accessible access still needs that one unit compliant. See ada accessible porta potty for spec details.
Can I use hand sanitizer instead of a handwashing station?
No, not where 1926.51(f)(1) applies, meaning paint, coatings, herbicide or insecticide work. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device. Sanitizer alone does not meet that standard. A portable sink rental satisfies it properly.
What is the OSHA ratio for a 200-plus worker site?
At 200 or more workers, OSHA 1926.51(c)(1) requires 1 toilet seat plus 1 urinal per 50 workers, a lighter ratio than smaller crews. Large Savannah builds often shift to multiple restroom trailer rental units instead of dozens of single stalls at that scale.
Do farm sites follow the same OSHA toilet rule as construction?
No. Agricultural field sanitation falls under OSHA 1928.110, requiring 1 facility per 20 hand-labor workers within a quarter mile walk, separate from the construction ratio in 1926.51(c)(1). See farm and agricultural restrooms for specifics.
