What Does Construction Portable Toilet Rental Cost in Knoxville?
A standard porta john for a Knoxville job site runs from about $100 a day up to $350, with monthly rates between $125 and $325 depending on service frequency and how many units you need on site. Most crews skip the daily rate and go monthly once the job runs past a few weeks. Delivery adds a separate fee, typically $120 to $420 a month depending on distance and access. Jobs out toward Karns, 9.8 miles west, or Powell, 10.5 miles northwest, still fall inside our normal delivery radius. For a full breakdown by unit type and duration, see porta potty rental cost in Knoxville or check the monthly porta potty rental numbers directly. If you are pricing a short punch-list job instead of a full build, the porta potty rental per day page has the daily figures broken out separately.

How Many Portable Toilets Does a Construction Site Need?
OSHA 1926.51(c) sets the baseline: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers as the crew grows past that, and one per 50 once you're at 200 or more. That's the federal floor for OSHA portable toilet requirements, and it applies whether you're staffing a highway job outside Knoxville or a subdivision build near Farragut, 17.0 miles southwest. Crews handling paints, coatings, herbicides or insecticides also need washing facilities under OSHA 1926.51(f)(1), separate from toilet counts. If your site has electrical trades running GFCI-protected circuits under OSHA 1926.404(b)(1)(ii), pair the units with a handwashing station rental so hands get cleaned before breaks, not just at lunch. Not sure how many units your headcount actually requires? Run the numbers on how many porta potties do I need before you order. Site housekeeping rules under OSHA 1926.25 also mean loose debris needs a place to go, which is where a roll-off dumpster rental earns its spot on the invoice next to the toilets.
Do Construction Sites Need ADA-Accessible Units?
Yes, once you're clustering multiple portable toilets on one site. ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, and never fewer than one, so a site running six or eight standard units needs at least one ADA unit in the mix. Accessible units also need a 60 inch turning circle under ADA Standards 304.3.1 and a 32 inch clear door opening per ADA Standards 404.2.3, so placement matters as much as the order itself. Weekly ADA rental in Knoxville runs $250 to $400 once you price it against a multi-day stretch, which is worth confirming before you commit to a schedule. Check the ADA accessible porta potty page for unit specs, and use the porta potty placement guide to figure out where the accessible route needs to run, since ADA 403.5.1 calls for a 36 inch clear path to the unit itself.
Where Should Units Go on a Job Site?
Ground stability and truck access decide this more than anything else. A standard unit sits on a footprint of about 44 by 48 inches and stands roughly 92 inches tall, which is easy to tuck near a trailer or fence line, but a roll-off delivery needs about 60 feet of straight clearance behind the truck to drop or swap a container. That clearance requirement rules out a lot of tight urban lots in Knoxville, so it's worth walking the site before ordering a construction dumpster rental alongside your toilets. Surface stability matters too, since ADA 302.1 calls for stable, firm, slip-resistant ground under accessible units, which rules out loose gravel or soft turf as a placement choice. If the site perimeter needs to be secured overnight, a temporary fence rental or chain link temporary fence keeps foot traffic and liability down. Sites running mobile crews sometimes add a mobile office trailer rental or a storage container rental for tools, both of which have the same access needs as the toilets and dumpsters.
Job trailers and equipment lockups also draw theft risk, so pairing fencing with a storage container rental cost comparison up front saves a change order later. For larger commercial builds needing three or four services coordinated on one schedule, start at the Construction Site Services overview or request a combined quote through request a quote rather than ordering piecemeal.
What size dumpster does a typical construction job need?
Most residential remodels use a mid-size roll-off, while full builds need larger containers for framing and drywall waste. Check dumpster sizes and dimensions to match container size to job type, and confirm weight limits before loading, since overage fees add up fast on demolition debris.
Does portable toilet rental for construction sites cost more with delivery?
Yes, delivery is billed separately from the unit rental. Expect $100 to $500 for a single delivery trip, or $120 to $420 if billed monthly. Distance, access and how many units go on one trip all affect the final delivery fee.
Can I rent portable toilets for a construction site outside Knoxville?
Yes. We regularly deliver to Halls, 10.9 miles north, Alcoa, 14.8 miles south, and Maryville, 19.0 miles south, along with sites closer in. Check Service Areas for the full coverage map before you order.
Are permits required to place a porta potty on a construction site?
Placement in the public right of way needs confirming with the city before delivery. See porta potty permit requirements for what to check, since rules vary by lot and by street frontage.
Should I pair a handwashing station with my portable toilets?
Yes, especially with painting or chemical work on site. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at washing stations, not just sanitizer. See handwashing station requirements for setup details.
