How Much Does a Porta Potty Cost Per Month?
The short answer: a standard porta potty rental in Denver falls between $125 and $325 a month, and that spread mostly comes down to service frequency and how many units you need on site. A single unit for a small crew sits at the low end. A multi-unit setup for a construction site, billed under construction site services, lands higher because of servicing labor. Delivery is usually a separate line, and monthly delivery fees in Denver run $120 to $420 depending on distance and access. If your job needs a flushing option instead of a standard chemical toilet, check the deluxe flushable porta potty page, since deluxe units price differently and don't share the same monthly band. ADA-compliant units also rent separately; see ADA accessible porta potty pricing before you finalize a quote. For a full cost breakdown across all rental lengths, the porta potty rental cost page compares day, week, and month pricing side by side.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $185-$240 | not sold monthly |
| deluxe | $85-$1,200 | $150-$290 | not sold monthly |
Why Is Long Term Porta Potty Rental Cheaper Per Day?
Because service costs spread out. A single service visit under ANSI/PSAI Z4.3 covers up to 10 users over a 40 hour week as the baseline interval, so a longer contract lets Denver Porta Pros route trucks more efficiently instead of running one-off trips. That efficiency shows up in the rate. Compare it to a porta potty rental per day quote and you'll see the daily-equivalent cost drop hard once you commit to 30 days. A homeowner doing a slow renovation in Denver, tracked on the home renovation porta potty page, almost always comes out ahead going monthly instead of renewing a weekend rate every few days. The same logic applies to a farm operation running farm and agricultural restrooms through a full growing season. Long term contracts also lock in delivery once instead of billing a delivery fee per visit, which matters since delivery alone can run $100 to $500 depending on the job.
Do I Need a Permit for a Long Term Unit in Denver?
Maybe, and it depends on where the unit sits. If you're placing a toilet on a public sidewalk, street, or right of way anywhere in Denver, that placement needs confirming directly with the city before delivery. We are not going to guess at a permit number here, because getting it wrong costs you a fine and costs us your trust. The porta potty permit requirements page walks through what to ask the city and when. If the unit stays entirely on private property, most jobs skip the permit question entirely. Either way, plan your porta potty placement guide around a stable, level surface, since ADA Standards 302.1 calls for firm, slip-resistant ground wherever an accessible unit is set. A construction site running a monthly contract should also review dumpster permit requirements at the same time, since roll-off placement often triggers a separate city review.
How Many Units Do I Need for a Month-Long Job?
Start with headcount, not guesswork. OSHA 1926.51(c) sets the baseline for construction sites: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers as the crew grows past that, dropping to one per 50 once you hit 200 workers or more. A crew of 15 in Denver needs one unit. A crew of 60 needs at least two, plus a urinal. If any part of the job involves applying paints, coatings, or insecticides, OSHA 1926.51(f)(1) also requires washing facilities for that work, separate from the toilet count, which is where a handwashing station rental or a portable sink rental comes in. Clustered units also need at least one accessible unit under ADA Standards 213.2, even if only 5 percent of the total is required. Run the numbers yourself with how many porta potties do I need or read the full breakdown on OSHA portable toilet requirements before you place the order. Jobs in nearby Glendale, about 7.4 miles southwest of Denver, and Derby, 8.2 miles north, follow the same OSHA math regardless of city line.
How often is a monthly rental unit serviced?
Standard service follows the ANSI/PSAI Z4.3 baseline of one visit per week for typical usage, but a busy construction crew often needs two visits. Denver Porta Pros adjusts frequency based on headcount, not just the calendar, so a 40-person site gets serviced more than a 5-person site on the same monthly plan.
Can I switch from weekly to monthly billing mid-rental?
Yes, most contracts convert cleanly once you pass the two or three week mark, since the monthly rate already assumes a longer commitment. Call before your current billing cycle renews so the switch lines up with your next scheduled service instead of splitting a week.
Does a monthly rental include delivery and pickup?
Not always, delivery is billed separately in most cases. Monthly delivery fees run $120 to $420 depending on distance and site access, and that's a one-time charge covering both drop-off and final pickup, not a recurring line on your invoice.
What's the difference between a standard and deluxe unit for a month-long job?
A standard unit uses a 60 to 70 gallon holding tank and standard chemical service, while a deluxe unit typically adds a flushing mechanism and better interior finish. Deluxe units don't have a published monthly band here, so ask for a direct quote if your job needs one for 30 days.
Do I need an accessible unit if I only have one porta potty on site?
Yes, if you're clustering units, ADA Standards 213.2 requires at least one accessible unit even when only 5 percent of the total would round down to zero. A single-unit job still needs to meet the same access rules, including a 60 inch turning space under ADA Standards 304.3.1.
