Where should a porta potty go on a job site?
Pick flat, compacted ground first. A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so it doesn't need much of a footprint, but it does need to sit level or servicing crews can't safely pump it. Keep units away from soft dirt, slopes, and drainage paths. On active construction sites, construction site services crews usually place units near the entrance so workers aren't walking across the whole lot. If you're also renting a dumpster, remember a roll-off delivery needs about 60 feet of straight clearance behind the truck, so plan the two placements separately. For ADA units, the ground has to be stable, firm and slip resistant under ADA Standards section 302.1, and the unit needs a 60 inch turning circle nearby per section 304.3.1. Check the porta potty placement guide sibling page on headcount before you finalize spacing, and review porta potty permit requirements if the unit sits anywhere near a public sidewalk in Lehi.
Do I need a permit to place a porta potty in Lehi?
Placement in the public right of way needs confirming with the city; we're not going to guess at a Lehi ordinance number here. If your unit sits entirely on private property, set back from the sidewalk, you're usually fine without extra paperwork, but anything touching a street, curb strip or right of way should get a call to the city first. This matters even more for dumpsters: a dumpster placement permit is a separate question from a dumpster placement permit cost, and both vary block by block. See dumpster permit requirements before your roll-off shows up, and check porta potty permit requirements for the toilet side. If you're running an event near American Fork, 5.9 miles southeast of Lehi, or Draper, 8.4 miles north, permit rules shift at the city line, so don't assume Lehi's answer travels with you.
How many units do I need and how far apart should they sit?
OSHA 1926.51(c) sets the baseline for construction crews: 1 toilet for 20 workers or fewer, then 1 toilet and 1 urinal per 40 workers once you pass 20, scaling to 1 per 50 at 200 or more. Space multiple units at least a few feet apart for service access, and cluster them near breakrooms rather than scattering them across a large site. ADA Standards section 213.2 requires at least 5 percent of a cluster of single-user units be accessible, with a minimum of one no matter how small the group is. For events, event restroom rental planning in Lehi should account for crowd flow. weddings and festivals concentrate foot traffic near stages and food trucks, so festival restroom rental and wedding restroom rental both benefit from placing units along the perimeter, not the center. A standard porta potty rental unit runs a 60 to 70 gallon holding tank, and ANSI/PSAI Z4.3 sets one service visit per week as the baseline for up to 10 users over a 40 hour week, so plan return access accordingly.
What about hand-washing stations, trailers, and other equipment near the unit?
Handwashing setups need their own space and their own rules. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not sanitizer alone, so budget room for a proper handwashing station rental or portable sink rental next to the toilets, not instead of them. If your sink is an Ozark River unit and a spray head or drain fitting fails mid-job, sourcing ozark river portable sink replacement parts quickly keeps a rental on schedule rather than pulled from service. For jobs involving paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities for that specific contaminant exposure, so place a sink within easy reach of that work area. Restroom trailers need more room than a standard unit. a restroom trailer rental or 4 stall restroom trailer needs level, solid ground plus clearance for tank service, similar to the roll-off's 60 foot rule. If you're storing tools or files on site, a mobile office trailer rental sits well away from the sanitation cluster, and if a door gets damaged, mobile office trailer replacement doors are a separate repair conversation from anything sanitation-related. Keep temporary fence rental panels between the equipment zone and public walkways, especially near crowd control barrier rental setups at larger events.
FAQ
Can I place a porta potty on a sidewalk or street in Lehi?
Generally no, not without checking first. Public right of way placement needs city confirmation, since Lehi's specific rule isn't something to guess at. Keep the unit on private property set back from the curb, and if the job requires street space, call the city before delivery day, not after.
How far should a septic tank or holding tank be from the placement area?
A residential septic tank is typically pumped every 3 to 5 years depending on tank size and household size, so plan pump-truck access near that line, not just the toilet cluster. If you're near a rural property outside Lehi, a placerville septic pumping service style setup still needs the same truck clearance. See septic pumping service for scheduling.
Do ADA units need special placement?
Yes. ADA Standards section 405.2 caps ramp slope at 1:12 if there's any grade change, and the door needs a 32 inch clear opening under section 404.2.3. Place the ADA accessible porta potty on the flattest ground available, with a clear approach path at least 36 inches wide per section 403.5.1.
What ground surface works best under a unit?
Level, compacted gravel or asphalt beats grass or dirt every time. Soft ground shifts under a full 60 to 70 gallon tank and can tip a unit. If the site is muddy, lay plywood or gravel first. Ask about porta potty in winter placement if the job runs through freezing months.
How close can a dumpster sit to a porta potty?
There's no fixed spacing rule between them, but each needs its own clearance. The roll-off needs roughly 60 feet behind it for delivery, so don't box it in with toilets, fencing or a storage container rental unit sitting too close to the drop zone.
