Construction sites need 1 toilet for every 20 workers under OSHA 1926.51(c), with the ratio changing at 20 and again at 200 workers. General industry sites follow a separate table under 29 CFR 1910.141. These are the same numbers behind cal osha portable toilet requirements and cal osha portable toilet requirements construction guidance, since California's rule mirrors the federal ratio for jobsite counts. Orem Porta Pros sizes crews correctly the first time so you are not scrambling mid-job.
The rule is simpler than most contractors expect. OSHA 1926.51(c) sets it out plainly: 1 toilet seat for 20 workers or fewer on a construction site. Once you pass 20 workers, you add 1 seat and 1 urinal per 40 workers, and that ratio holds until you hit 200 workers, at which point it shifts to 1 seat and 1 urinal per 50. If your project sits in Orem and runs a 15-person crew, one standard porta potty rental covers you. A 45-person job needs closer to two units. Note this is the construction standard. If your operation counts as general industry rather than a jobsite, the ratios fall under OSHA 1910.141(c)(1)(i) instead, which uses employee headcount differently. Not sure which applies? Our construction site services page walks through both, and our how many porta potties do I need guide runs the math for your actual crew size, the same question crews search as how many porta potties do i need osha when they are trying to size a bid. Water matters too: OSHA 1926.51(a)(1) requires an adequate supply of potable water at every place of employment, which is why job sites often pair toilets with a handwashing station rental or a portable sink rental rather than treating sanitation as an afterthought.
People assume OSHA requires handwashing stations everywhere. It does not, not as a blanket rule. OSHA 1926.51(f)(1) kicks in specifically where workers are applying paints, coatings, herbicides or insecticides, or handling other harmful contaminants. If your crew in Orem is spraying stucco sealant or working with pesticide treatments, you need washing facilities on site, full stop. For everything else, general sanitation rules under 1926.51(c) still apply, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device wherever washing facilities exist. Hand sanitizer alone does not satisfy that standard, so a hand sanitizer station rental is a supplement, not a substitute. For crews that need the real thing, pair units with a portable sink rental and review handwashing requirements before your first inspection. Farms and agricultural operations fall under a different rule entirely: OSHA 1928.110 requires potable water, toilets and handwashing for hand-labor employees, at 1 facility per 20 workers, located within a quarter mile walk. That distance requirement is the closest thing OSHA has to a portable toilet placement rule, and it is usually what people mean when they search osha portable toilet distance requirements; it shows up on our farm and agricultural restrooms page.
Not in the way most people expect. OSHA does not publish a universal number of feet between a work area and a toilet. What it does regulate is access and safety around the unit itself. Barricades near a placement, if used, need to meet ANSI D6.1 under OSHA 1926.202. Illumination in work areas, including paths to sanitation, falls under OSHA 1926.56(a). Debris and scrap around a unit should be cleared per OSHA 1926.25, since a toilet blocked by material stacks isn't compliant even if the count is right. The one hard distance figure that does exist comes from agriculture: 1928.110 sets a quarter-mile maximum walk to reach facilities. For everyone else, the practical guidance is in our porta potty placement guide, which covers clearance, ground stability and delivery access. Roll-off deliveries in particular need about 60 feet of straight clearance behind the truck, worth checking before your roll-off dumpster rental shows up. If your Orem site is tight, mention it when you book. Crews searching portable toilet rental oshawa are usually looking for this same clearance and placement guidance under a different spelling of Orem, so the same delivery rules apply here.
Yes, once you cluster units. ADA Standards section 213.2 requires that where portable toilets are grouped together, at least 5 percent must be accessible, with a minimum of 1 unit regardless of total count. That accessible unit needs a 36 inch clear route under section 403.5.1, a 32 inch door opening under 404.2.3, and a 60 inch turning circle inside under 304.3.1. Reach ranges and operable parts have their own specs too, covered on our ADA restroom requirements page. Most Orem contractors with mixed crews or public-facing sites order at least one ADA accessible porta potty alongside standard units. Weekly ADA rental typically runs in the $120 to $240 range depending on term and add-ons; check our porta potty rental cost page for the full breakdown. Event organizers in Orem, Provo, 5.6 miles southeast, or Pleasant Grove, 6.4 miles northwest, should plan for the same ratio. Our event restroom rental and ADA accessible porta potty pages both cover ordering ahead of inspection.
One unit satisfies OSHA 1926.51(c) at exactly 20 workers, since the ratio only requires an additional seat once you exceed 20. Most crews order a second unit anyway for uptime during servicing. Check our how many porta potties do I need guide for crew-size math specific to Orem jobs.
No universal distance exists outside agriculture, where 1928.110 sets a quarter-mile walking limit. Construction sites follow access and safety rules instead, covering lighting, barricades and clear pathways rather than a fixed footage number. Our porta potty placement guide covers practical setup.
No. Where 1926.51(f)(1) applies, meaning paints, coatings, herbicides or insecticides are in use, actual washing facilities with soap and towels are required under 29 CFR 1910.141(d)(2). Sanitizer supplements handwashing but never replaces it on a compliant job site.
Inspectors typically flag insufficient units, blocked access or missing accessible units under ADA 213.2. Orem Porta Pros can deliver same-day in most cases; call ahead and check our emergency porta potty rental page for availability and rates.
Yes. Waste disposal and chutes fall under OSHA 1926.252, and general housekeeping under 1926.25. These apply alongside sanitation rules, not instead of them. See roll-off dumpster rental and storage container rental for unit specs and delivery clearance needs; the same page comes up for storage container rental oshawa searches, since it is another common misspelling of Orem.
