How many porta potties does OSHA require?
The math is simple once you know the table. OSHA 1926.51(c)(1) sets 1 toilet facility for 20 workers or fewer on a construction site. From 20 up to 200 workers, you need 1 toilet seat and 1 urinal per 40 people. At 200 or more, it drops to 1 seat and 1 urinal per 50. A 35-person framing crew in Conway needs 1 unit under the first tier calculation, but most supervisors round up rather than run tight. Our how many porta potties do I need guide walks through the math for mixed crew sizes. If your job runs outside construction, general industry sites follow 1910.141(c)(1)(i) instead, which uses a different employee-count table. Farms with hand-labor crews fall under a separate rule, 1928.110, which calls for one facility per 20 workers within a quarter mile walk. Know which rule applies before you order. Note that cal osha portable toilet requirements and cal osha portable toilet requirements construction differ from the federal table above, since Cal OSHA governs California job sites, not Arkansas ones.
| workers | toilets required |
|---|---|
| 1 to 20 | 1 |
| 21 to 40 | 2 |
| 41 to 60 | 3 |
| 61 to 80 | 4 |
| 81 to 100 | 5 |
Standard units run $100 to $350 a day depending on term and delivery, and a monthly rental typically lands between $125 and $325. For full pricing logic, see porta potty rental cost.
What about handwashing and water requirements?
OSHA 1926.51(a)(1) requires an adequate supply of potable water at every place of employment. That is separate from toilets, and separate from handwashing stations. If your crew applies paints, coatings, herbicides or insecticides, 1926.51(f)(1) kicks in and requires washing facilities for those specific tasks. It does not apply to general jobsite handwashing. For general industry workplaces, 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at wash stations. Hand sanitizer alone does not satisfy that rule. Conway Porta Pros supplies handwashing station rentals and portable sink rentals built to pair with toilet units on the same delivery. Renovation crews working inside occupied homes in Conway often add a station near the entry point rather than inside the work zone. If your project involves spraying or coating work, plan the wash station location before crews start, not after an inspector asks. Pair that with a porta john rental or standard unit and you have covered both rules with one delivery stop.
What are the OSHA distance and placement rules?
OSHA does not publish osha portable toilet distance requirements as a fixed number of feet, but ANSI/PSAI Z4.3 sets the servicing baseline: one visit per week covers up to 10 users over a 40-hour week. Heavier crews need more frequent service, not more distance rules. Practical placement still matters. ADA Standards 403.5.1 calls for a 36 inch clear route to any accessible unit, and 404.2.3 requires a 32 inch clear door opening. Where you cluster multiple standard units, ADA 213.2 requires at least 5 percent to be accessible, with a minimum of one. Our ADA accessible porta potty units meet that spec, and weekly rental for an ADA unit runs $120 to $240. See our porta potty placement guide for site layout examples. Keep units on stable, level ground, since ADA 302.1 requires slip-resistant surfaces at accessible units. A 4 stall restroom trailer is worth considering on tighter Conway lots where a cluster of standard units would eat too much staging space. Roll-off deliveries need about 60 feet of straight clearance behind the truck, worth remembering if toilets and a roll-off dumpster rental share the same access lane.
Does OSHA require porta potties on every construction site?
Yes. Any construction site with employees needs sanitation facilities under 1926.51(c)(1), regardless of job length. There is no small-job exemption. A one-day demolition crew still needs a toilet on site, which is why emergency porta potty rental exists for short-notice jobs. Housekeeping rules under 1926.25 and debris disposal under 1926.252 often get inspected alongside sanitation, so a clean site with a properly stocked toilet tends to draw less scrutiny overall. Crews working near Mayflower, 10.9 miles south of Conway, or Greenbrier, 15.4 miles northeast, follow the same federal rule regardless of which side of the city line the job sits on. For jobs that also need a temporary fence rental or light tower rental, bundling deliveries with your toilet order saves a trip. Our construction site services page covers the full setup for active job sites in Conway. Some crews search for portable toilet rental oshawa or storage container rental oshawa while comparing out-of-state providers, but this page and our storage container rental service cover Conway, AR job sites specifically.
Does Cal OSHA use the same ratio as federal OSHA?
Cal OSHA applies in California only, not Arkansas. Conway job sites follow federal OSHA 1926.51(c)(1) for construction and 1910.141(c)(1)(i) for general industry. If you have crews working across state lines, check which set of rules governs the job's actual location.
How many porta potties do I need for a 50-person crew?
Under 1926.51(c)(1), 50 workers falls in the 20-to-200 tier: 1 toilet seat and 1 urinal per 40 workers. That means 2 of each for a 50-person crew. Many contractors round up for comfort. See our full breakdown for larger crew sizes.
Do OSHA rules apply to short-term rentals?
Yes. Duration does not exempt a site from 1926.51(c)(1). A one-day job needs the same ratio as a six-month build. Standard unit daily rates start at $100, so short jobs are not a hardship.
What is the difference between OSHA and ADA requirements?
OSHA sets minimum toilet counts by crew size. ADA Standards 213.2 sets accessibility requirements for units within any cluster. Both can apply on the same site. Our ADA restroom requirements page covers the overlap in detail.
Can I rent a storage container alongside porta potties for the same job?
Yes. Many Conway contractors order both on one delivery. A storage container rental or 20ft storage container works well for tool storage next to a toilet cluster, and scheduling them together often simplifies the delivery window.
