How many porta potties do I need under OSHA?
Start with the headcount and let OSHA 1926.51(c) do the math. Twenty workers or fewer means one unit is enough. Cross 20 and you owe one toilet seat plus one urinal per 40 workers, and that ratio holds until you hit 200 people, where it drops to one seat and one urinal per 50. A 35-person framing crew in Arcadia needs two units, not one, because 35 clears the first threshold. Our how many porta potties do I need guide walks through the count by trade and shift pattern. For a general contractor running two shifts on one lot, order enough standard porta potty rental units to cover the peak headcount on site at once, not the total roster across both shifts. If your crew swings above 200 on a bigger build, the ratio changes again, and that is worth a call before you order.
What does Cal/OSHA require beyond the federal standard?
California generally follows the federal 1926.51(c) ratio for construction toilets, and adds its own field sanitation and drinking water rules layered on top of the OSHA baseline. OSHA 1926.51(a)(1) requires an adequate supply of potable water at every job site, separate from the toilet count. Agricultural operations fall under a different rule entirely: OSHA 1928.110 sets one facility per 20 hand-labor employees, and it has to sit within a quarter mile walk of where people are working. That distance rule matters for growers near farm and agricultural restrooms work outside Arcadia proper, and it is the closest thing in the code to an osha portable toilet distance requirements standard, since general construction sites under cal osha portable toilet requirements have no set foot distance at all. Permit placement in the public right of way is not something we can confirm on this page. Check with the City of Arcadia before setting a unit at the curb or on a sidewalk easement. Our porta potty permit requirements page covers what to ask when you call.
Where should portable toilets be placed on a job site?
Placement is about access, not guesswork. A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so give it flat, stable ground per ADA Standards 302.1 and enough clearance that a service truck can reach it weekly. If any units on site need to be accessible, ADA Standards 213.2 requires at least 5 percent of a cluster to meet accessible specs, with a minimum of one unit regardless of cluster size. That accessible unit needs a 36 inch clear path per ADA Standards 403.5.1 and a 32 inch door opening per ADA Standards 404.2.3, plus a 60 inch turning circle inside per ADA Standards 304.3.1. Our ADA accessible porta potty page details the full spec sheet. For general layout logic, from spacing between units to keeping units away from electrical panels covered under OSHA 1926.404(b)(1)(ii), see our porta potty placement guide. Sites in Arcadia running roll-off dumpsters alongside restrooms should also plan 60 feet of straight clearance behind the truck for delivery.
Do handwashing stations count toward OSHA compliance?
Yes, but the rule that applies depends on the work. General sanitation and toilet counts fall under OSHA 1926.51(c). If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in and requires washing facilities specific to that contaminant exposure, separate from the toilet count. Under 29 CFR 1910.141(d)(2), any washing facility needs soap and a way to dry hands, towels or a dispenser, and hand sanitizer alone does not satisfy that rule. A framing crew doesn't trigger 1926.51(f)(1), but a painting subcontractor working the same Arcadia site does. Pair a handwashing station rental with your toilets rather than relying on sanitizer stations alone if paint or chemical work is part of the scope. Check our handwashing requirements page for which rule applies to which trade before the inspector asks. Crews doing renovation work should also look at home renovation porta potty options sized for smaller lots.
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| standard | week | $200 |
| standard | month | $200 |
| ada | week | $185 |
Prices vary by site and duration; see porta potty rental cost and porta potty rental per day for the full breakdown, or monthly porta potty rental if the job runs long. Contractors juggling restrooms with a roll-off dumpster rental or a temporary fence rental around the perimeter should bundle delivery to save a trip charge. Sites needing overnight security might also add a storage container rental for tools alongside the restrooms; a container works just as well for equipment as it does holding site records if your crew asks about storage container rental near Arcadia. Some callers searching porta potty rental oshawa or storage container rental oshawa land here by mistake, but Arcadia Porta Pros serves this city and its immediate reach, roughly the stretch from Temple City 3.3 miles southwest to Monrovia 5.1 miles northeast.
How many porta potties do I need for a 20-person crew?
One toilet covers a crew of 20 or fewer under OSHA 1926.51(c). At 21 workers, you cross into the next bracket and need to add a toilet seat and urinal per 40 people. Check your peak on-site headcount, not your total payroll, before ordering from portable toilet rental.
Does OSHA require a distance limit for portable toilets on site?
OSHA 1926.51(c) does not set a specific foot distance for construction sites. Agricultural work under 1928.110 does specify a quarter mile walk to reach a facility. For general job sites, place units for reasonable walking access; see our porta potty placement guide for layout logic.
Can hand sanitizer replace a handwashing station for OSHA compliance?
No. Under 29 CFR 1910.141(d)(2), a compliant washing facility needs soap and towels or a hand-drying device. Sanitizer alone does not meet that standard. Pair any portable sink rental or hand sanitizer station rental with proper handwashing units where the rule applies.
Do I need an ADA-accessible unit on every job site?
If you're clustering portable toilets, ADA Standards 213.2 requires at least 5 percent to be accessible, with a minimum of one regardless of how many units you order. A single-unit site still needs to consider accessible design depending on public access. See ADA restroom requirements for specifics.
What happens if my Arcadia site fails an OSHA sanitation check?
Non-compliance risks a stop-work order or citation tied to 1926.51(c) headcount ratios. Recheck your crew size against the toilet count, confirm handwashing setup if paint or chemical work is happening, and call Arcadia Porta Pros to adjust the order same day if you're short.
