A monthly porta potty rental in Durham runs 125 to 325 dollars per unit, with most standard units landing near 200 dollars a month once delivery is worked in. Long term portable toilet rental gets cheaper per week the longer you keep the unit, which is why builders and land crews book by the month instead of by the day.
Standard units land in a 125 to 325 dollar monthly band, and that spread comes down to how many units you need and how far the truck has to drive. A single unit on a job site close to downtown Durham costs less to service than three units spread across a property near Gorman, 8.3 miles northeast. Delivery fees for a month-long order fall between 120 and 420 dollars, and that number depends on distance and how many stops the driver makes. If you are comparing this against shorter terms, porta potty rental per day pricing helps you see why monthly wins for anything past a few weeks. Long term porta potty rental cost also flexes with the unit type: a standard porta potty rental is your baseline, while a deluxe flushable porta potty or an ADA accessible porta potty both carry their own monthly range. For a full cost breakdown across durations, the porta potty rental cost page lays out day, week, and month numbers side by side.
A monthly rental from Durham Porta Pros includes the unit, a set service schedule, and delivery within the quoted fee. ANSI/PSAI Z4.3, the portable sanitation service standard, sets a baseline service interval of once a week for up to 10 users over a 40 hour week, and that baseline is what most monthly plans in Durham are built around. Each standard unit holds a 60 to 70 gallon tank and sits about 44 by 48 inches on the ground, standing roughly 92 inches tall, so placement on a tight residential lot near Chapel Hill, 9.6 miles southwest, still needs planning. If your crew size or hours run heavier than that baseline, ask about stepping up service frequency rather than unit count. Construction sites also fall under OSHA portable toilet requirements: OSHA 1926.51(c)(1) sets 1 toilet for 20 workers or fewer, moving to 1 toilet and 1 urinal per 40 workers once you cross 20, and 1 per 50 once you hit 200 or more. That ratio is worth checking before you settle on how many units your monthly plan needs. For crews doing painting, coatings, or pesticide work, OSHA 1926.51(f)(1) requires washing facilities on top of standard toilets, which is where a handwashing station rental or portable sink rental fits into the monthly order.
A single day rental for a standard unit runs 100 to 350 dollars, and a weekend runs 125 to 400 dollars, but stretch that same unit to a full week and the per-day cost drops because service and delivery get spread across more days of use. Push it to a month and the same logic compounds again, landing most standard units at 125 to 325 dollars for 30 days of use instead of paying a weekly rate four times over. This is the same reason monthly porta potty rental makes sense for any Durham job stretching past a few weeks, whether it is a home addition covered on our home renovation porta potty page or a full construction site services contract. Below is how the durations compare for a standard unit and an ADA unit.
| unit | day | week | month |
|---|---|---|---|
| standard | 100 to 350 | 130 to 500 | 125 to 325 |
| ada | 200 to 400 | 120 to 240 | not sold by month |
Notice the ADA weekly band actually sits below its daily band here because ADA units are typically ordered short term for events, not as a monthly fixture. If your job needs one anyway, ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, never fewer than one, so factor that into a multi-unit monthly order.
Any Durham job running longer than four to six weeks usually breaks even faster on a monthly plan than on repeated weekly bookings, since the per-day cost keeps falling as the term extends. A land-clearing or grading job near Morrisville, 13.5 miles south, that runs a full season is the clearest case: you are not guessing week to week, you are locking a rate and a service day for the length of the project. Builders juggling a dumpster alongside the toilets should check roll-off dumpster rental or the dumpster rental cost page, since site services often get quoted together. If the property also needs a barrier around the work zone, temporary fence rental runs 30 to 75 dollars a day and pairs naturally with a monthly toilet order. For agricultural operations, OSHA 1928.110 requires field sanitation with a facility per 20 hand-labor employees within a quarter mile walk, which is worth reviewing on our farm and agricultural restrooms page before locking a monthly count.
Start with OSHA 1926.51(c)(1): one toilet per 20 workers, then add a unit as you cross each ratio break. Crew size, shift length, and site layout all matter. Our how many porta potties do I need guide walks through the math with worked examples.
Yes, service is built into the monthly rate, typically weekly per the ANSI/PSAI Z4.3 baseline interval. Heavier crews or higher headcounts may need more frequent visits. Ask when you request a quote so the schedule matches actual site traffic, not the minimum.
Usually yes, with a prorated adjustment for the switch. Deluxe units run 150 to 290 dollars weekly, so a mid-month swap changes your total. Call ahead so the swap happens on a scheduled service day, not a special trip.
Delivery is billed separately from the unit rate, usually 120 to 420 dollars for a month-long placement depending on distance and site access. Jobs farther from Durham, like sites near Wake Forest, 24.6 miles east, sit toward the higher end of that range.
Monthly rentals typically roll forward automatically unless you give notice. There is no penalty for extending, since the pricing structure already favors longer terms. Just confirm the renewal date so service stays on schedule without a gap.
