How much does a porta potty cost per month?
People searching porta potty rental cost per month or portable toilet rental cost per month usually want one number, and it depends on unit count and site access more than anything else.
Standard units run $125 to $325 a month, and that spread mostly comes down to how many service visits you need and how far the site sits from Fairfield. A standard porta potty rental at the low end usually means one unit, easy truck access, and a weekly cleaning. Add a second or third unit, or a site out toward Suisun City 2.1 miles southeast, and the number climbs. Delivery itself is billed separately: expect $120 to $420 for a month-long placement, per our delivery pricing data. If you want a deluxe flushable porta potty instead of standard, plan on a higher monthly rate, and if the crew needs accessible fixtures, an ADA accessible porta potty has its own separate pricing tier. For anyone still comparing rental lengths, our porta potty rental cost page breaks down day, week, and month side by side, and the porta potty rental per day page is worth a look if your job might run shorter than expected.

Why does long term portable toilet rental cost less per day than short jobs?
Because the truck is already coming back. A one-day rental means a delivery trip and a pickup trip for a single use. A month-long placement spreads that same delivery cost over 20-plus working days, and the weekly service stop, based on the ANSI/PSAI Z4.3 baseline of one visit per week for up to 10 users over a 40 hour week, is routed alongside other stops in Fairfield instead of scheduled as a special trip. That's the whole reason long term porta potty rental cost and porta potty rental per month pricing look so different from a weekend rate. A construction crew running a six-month build gets a materially better per-day number than a two-day fencing crew renting the same unit. If your project is closer to a season than a weekend, check construction site services for how sanitation gets bundled with fencing and dumpsters on longer jobs.
| duration | low | typical | high |
|---|---|---|---|
| day | 100 | 150 | 350 |
| week | 130 | 200 | 500 |
| month | 125 | 200 | 325 |
Notice the month column sits close to the week column rather than four times higher. That compression is the entire argument for going long term instead of renewing weekly.
What affects my monthly rate?
Unit count, unit type, and site access drive the number more than anything else. OSHA 1926.51(c) sets the ratio that decides unit count on a jobsite: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers as headcount rises past that, and per 50 workers once you're at 200 or more. A crew of 15 needs one unit; a crew of 60 needs several, and that math is worth running before you call for a quote. Our how many porta potties do I need guide walks through the ratio in more detail. Site access matters too: a roll-off or trailer delivery needs about 60 feet of straight clearance behind the truck, and tight residential lots in older Fairfield neighborhoods sometimes don't have it, which changes where the unit can sit. If you're running a farm operation, note that OSHA 1928.110 requires field sanitation facilities within a quarter mile walk of hand-labor employees, at one facility per 20 workers, which is different math than a construction site. See farm and agricultural restrooms for that setup. Handwashing is billed separately from the toilet unit; a handwashing station rental or portable sink rental gets added to the monthly total if the crew is applying paints, coatings or similar contaminants, which triggers OSHA 1926.51(f)(1) washing requirements specifically for that paint, coating, herbicide or insecticide work.

Do I need a permit for a month-long placement in Fairfield?
Placement in the public right of way needs confirming with the city before you commit to a spot, since permit rules and any related fees are not something we publish here without checking first with Fairfield directly. If the unit sits entirely on private property, set back from the sidewalk and street, that's usually simpler, but you should still confirm with the city if you're at all unsure. Our porta potty permit requirements page and the general porta potty placement guide cover the questions to ask before delivery day. This matters more for month-long jobs than short ones, since a unit sitting in the wrong spot for four weeks draws more attention than one there for a weekend event.

Frequently asked questions
How many service visits come with a monthly rental?
Most monthly plans include weekly servicing, following the ANSI/PSAI Z4.3 baseline of one visit per week for up to 10 users. Higher-traffic sites can add visits. Ask about your specific headcount before signing, since a 40-person crew needs more than the baseline schedule covers.
Can I upgrade from standard to deluxe mid-rental?
Yes, most jobs can swap unit types between service visits. Check the deluxe flushable porta potty page for what's different, then call to adjust your existing order rather than starting a new contract.
Is a long term portable toilet rental cheaper than renting a restroom trailer?
For basic jobsite use, yes, standard units cost less monthly than a trailer. If workers need running water and privacy for a longer stay, a restroom trailer rental may be worth the higher monthly cost instead.
Does the monthly price include handwashing stations?
No, handwashing is priced and delivered separately from toilet units. Add a hand sanitizer station rental or full sink setup if OSHA 1926.51(f)(1) applies to paint, coating, herbicide or insecticide work on your site, or if general sanitation needs under OSHA 1926.51(c) push you toward it.
What happens if my project runs past the first month?
Rentals typically continue month to month until you call for pickup. There's no penalty for extending, and Fairfield Porta Pros can move the unit if your site location changes mid-project.
