How Much Does a Porta Potty Cost Per Month?
Monthly pricing depends on unit type, how often it gets serviced, and where it sits on your San Mateo property. A standard porta potty rental typically falls between $125 and $325 a month, based on 24 data points we track. That is the workhorse option for a job site running past 30 days. If you need something nicer for a longer commercial job, a deluxe flushable porta potty costs more but skips the chemical-blue holding tank smell some crews complain about. Delivery adds a separate line, usually $120 to $420 a month depending on distance and access. If your site sits near Foster City, 4.7 miles east of San Mateo, or Belmont, 5.3 miles south, delivery routing rarely changes the quote much since both are close in. Compare that to a porta potty rental per day rate before you commit, because short jobs almost never make sense at a monthly rate. Anyone searching porta potty rental cost per month near me will find the same standard range applies citywide, since delivery distance moves the number more than neighborhood does.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$400 | not sold monthly |
| dumpster | $51-$112 | $426-$778 | $500-$778 |
| storage | n/a | n/a | $100-$250 |
Why Choose Long Term Porta Potty Rental Over Weekly?
Porta potty rental per month makes sense once a job stretches past a few weeks, and portable toilet rental cost per month tracks the same standard-unit range whether the site is a remodel or a farm build-out.
Long term porta potty rental locks in a flat monthly rate instead of restarting a weekly contract every seven days. A standard unit's holding tank runs 60 to 70 gallons, and ANSI/PSAI Z4.3 sets a baseline service interval of once weekly for up to 10 users across a 40-hour week. On a monthly plan, that servicing gets scheduled automatically instead of renegotiated. Crews running a construction site services contract in San Mateo like this because it matches how OSHA 1926.51(c)(1) counts toilets: one facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers as headcount climbs past that. A crew that stays steady over two or three months doesn't want to recalculate that ratio every week. If your job is closer to a weekend pour or a short punch list, though, a porta potty rental cost breakdown by day or weekend will save you money instead. Home projects also fit here. A home renovation porta potty rented monthly beats hauling portable units back and forth every time a sub shows up.
What Do I Need to Know Before Signing a Monthly Contract?
You need clearance, placement, and a service plan before signing. A standard unit measures about 44 by 48 inches on the ground and stands roughly 92 inches tall, so tight side yards in older San Mateo neighborhoods sometimes need a placement check first. Our porta potty placement guide covers ground stability, since ADA Standards section 302.1 requires floor and ground surfaces to be stable, firm and slip resistant wherever an accessible unit sits. If workers are applying paint, coatings, herbicides or insecticides on-site, OSHA 1926.51(f)(1) requires washing facilities beyond a basic toilet, which is where a handwashing station rental or portable sink rental comes in. Soap and towels matter here too. 29 CFR 1910.141(d)(2) specifically requires soap and towels or a hand drying device, not hand sanitizer alone, at any washing facility. Check our handwashing requirements page if you're not sure which standard applies to your crew size. Also confirm right-of-way placement with the City of San Mateo directly, since we have not verified specific curb or sidewalk permit rules and won't guess at them here.
Do Monthly Rentals Include ADA-Accessible Units?
Not automatically, and you should ask. ADA Standards section 213.2 requires that where single-user portable toilet units are clustered, at least 5 percent, and never fewer than one unit, be accessible. That rule kicks in fast once you're renting three or more standard units for a month-long job. An ADA accessible porta potty needs a 60 inch turning circle per ADA Standards section 304.3.1, plus a minimum 32 inch clear door opening under ADA Standards section 404.2.3, so it takes a bit more room than a standard unit. If your monthly job is a farm operation instead of a construction site, note that OSHA 1928.110 sets a different standard for agricultural field sanitation, requiring one facility per 20 hand-labor employees within a quarter mile walk. That matters for anyone running farm and agricultural restrooms in the unincorporated edges near San Mateo. For bigger crews across a long job, pair your toilets with a 10 yard dumpster rental or a 20 yard dumpster rental on the same monthly cycle so pickup days line up.
Storage matters too on long jobs. Tools and materials sitting exposed for a month invite theft, so a lot of our monthly toilet customers add a storage container rental or a 20ft storage container to the same delivery. If the site needs a perimeter, a temporary fence rental or chain link temporary fence usually gets quoted at the same time, priced by the day but billed across the month. Septic-heavy sites running a month or longer sometimes need a septic pumping service too, especially since a typical 1,000 gallon residential tank gets pumped every 3 to 5 years, not monthly, so a long rental job is often the trigger that finally gets it scheduled. For crews working near Burlingame, 5.0 miles northwest of San Mateo, or further out toward San Bruno at 10.2 miles, delivery timing is worth confirming up front. Start with a request a quote so we can walk the site plan with you before the first unit lands.
How much does a porta potty cost per month?
Standard units run $125 to $325 a month based on 24 measured data points, with delivery billed separately at $120 to $420 depending on distance. Deluxe flushable units and ADA units price differently. Get a fixed quote before committing, since job size and service frequency both move the number.
Is long term porta potty rental cheaper than weekly?
Long term porta potty rental cost also beats renting a deluxe or ADA unit week over week, since those categories carry higher weekly rates than a standard unit's monthly plan.
Usually, yes. A weekly standard rental runs $130 to $500, and multiplying that across four weeks typically costs more than a flat monthly rate of $125 to $325. Long jobs almost always save money locking into the monthly plan instead of renewing weekly.
How many units do I need for a month-long job?
It depends on crew size. OSHA 1926.51(c)(1) requires one toilet for 20 workers or fewer, then additional seats and urinals as headcount grows past that. Our how many porta potties do i need guide walks through the exact ratios for bigger crews.
Do monthly rentals include weekly cleaning?
Yes, typically. ANSI/PSAI Z4.3 sets a baseline of one service visit weekly for up to 10 users across a 40-hour week. Heavier-use sites need more frequent service, which we scope during the quote so nothing gets missed mid-contract.
Can I switch from monthly to weekly mid-contract?
Yes, most jobs allow it. If your schedule shortens or stretches, we adjust the plan and rebill at the correct rate for the new duration. Call before the next billing cycle starts so the switch lines up cleanly with service days.
