OSHA Portable Toilet Requirements in Saint George, UT

Start with the headcount, not the site size. OSHA 1926.51(c)(1) sets the baseline at 1 toilet for 20 or fewer workers on a construction crew, then adds a toilet seat and urinal per 40 workers once you pass 20, and per 50 once you hit 200 or more. A 15 person framing crew in Saint George needs one standard porta potty rental. A 60 person crew needs closer to two seats plus urinals. Our how many porta potties do I need guide walks the math for mixed shifts. Water matters too: OSHA 1926.51(a)(1) requires an adequate supply of potable water at every jobsite, which is why crews often pair toilets with a handwashing station rental rather than assume a jobsite trailer covers it. If your crew works with paints, coatings or insecticides, OSHA 1926.51(f)(1) kicks in separately and requires washing facilities for that contaminant exposure specifically, not general hand cleanup. Ag operations follow a different rule: OSHA 1928.110 sets field sanitation at one facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters for growers near farm and agricultural restrooms work outside Saint George proper.

If you're clustering multiple standard units, yes, at least one has to meet ADA Standards section 213.2. A single unit on a small residential job usually doesn't trigger this, but public works, events and larger commercial sites in Saint George typically do. The accessible unit needs a 60 inch turning circle per ADA Standards section 304.3.1 and operable parts usable with one hand under ADA Standards section 309.4. Check our ADA restroom requirements page before you order, and price it against a standard porta potty rental so you know the delta going in.

Prices reflect measured ranges across the market; a porta potty rental cost breakdown has more detail, and monthly porta potty rental pricing runs separately from weekly.

Crews working near Washington, 7.8 miles northeast of Saint George, or Hurricane, 18.1 miles east, still fall under the same federal ratios; distance from the city doesn't change the OSHA math, only the delivery routing. If your project also needs a storage container rental or temporary fence rental alongside sanitation, bundling delivery often saves a trip charge. Housekeeping under OSHA 1926.25 and waste chute rules under OSHA 1926.252 apply separately from toilet counts, so don't conflate a clean site with a compliant one; they're two different inspection line items.

How many porta potties does OSHA require per worker?

OSHA 1926.51(c)(1) requires 1 toilet for 20 or fewer construction workers, then 1 toilet seat and 1 urinal per 40 workers up to 200, and per 50 workers beyond that. Crews near 15-20 people need just one unit; larger crews need to recalculate as headcount grows.

Does OSHA require handwashing stations on construction sites?

Only in specific contexts. OSHA 1926.51(f)(1) requires washing facilities where workers apply paints, coatings, herbicides or insecticides. General potable water access falls under OSHA 1926.51(a)(1) instead, which is broader and applies to nearly every site.

Can one porta potty cover a whole small crew?

Yes, for 20 workers or fewer under OSHA 1926.51(c)(1). Once you add a 21st worker, the rule adds a toilet seat and urinal per 40 additional workers, so recheck your count before final delivery.

Is a Cal OSHA portable toilet rule different from federal OSHA?

For Saint George jobsites, federal OSHA 1926.51(c)(1) applies, not Cal OSHA, since that's a California-specific standard. Contractors working both states should keep the citations separate in their site safety documentation to avoid confusion during inspection.

What about ADA units for events, not construction?

Same standard applies: ADA Standards section 213.2 requires at least one accessible unit in a cluster. Event organizers renting for a festival or wedding should check our event restroom rental page for planning ratios beyond the OSHA minimum.
