How many units do you need?
Start with headcount and duration, not guesswork. OSHA 1926.51(c) sets the baseline for construction sites: 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, and per 50 workers at 200 or more. For events, the math runs differently, and our guide to how many porta potties you need breaks that down by hours and guest count. Farm crews fall under a separate rule: OSHA 1928.110 requires one facility per 20 hand-labor employees, reachable within a quarter mile walk. Service interval matters too. ANSI/PSAI Z4.3 sets a baseline of one cleaning visit per week for up to 10 users over a 40 hour week, so a two-week Greenville job with 15 workers needs a tighter schedule, not the standard cadence. If you're renting for a wedding near downtown Greenville or a festival crowd, check our event restroom rental page before you lock in a number.
What type of unit should you rent?
Match the unit to the job, not the cheapest listing. A standard porta potty sits about 44 by 48 inches on the ground and stands roughly 92 inches tall, with a 60 to 70 gallon holding tank, fine for most Greenville construction sites and back yard projects. Weekend rates for a standard unit run higher per day than a weekly rental, so if your job spans more than three days, price out the week instead of stacking daily charges. A deluxe flushable unit makes sense for weddings or corporate events where guests expect more than a hand sanitizer pump. Need something closer to a real bathroom? Look at a 2 stall restroom trailer or the 4 stall version for larger gatherings. Under ADA Standards 213.2, any cluster of single-user units must include at least 5 percent accessible units, never fewer than one, so a bank of ten standard toilets needs at least one ADA-compliant unit on site.
| unit | day | week | month |
|---|---|---|---|
| standard | 100-350 | 130-500 | 125-325 |
| ada | 200-400 | 120-240 | - |
| deluxe | 85-1200 | 150-290 | - |

Where should the unit go?
Placement decides how well the unit actually works. ADA Standards 403.5.1 requires a 36 inch clear route to the unit, and 404.2.3 sets the minimum door opening at 32 inches, so check the path for gates, curbs or soft ground before delivery day. ADA Standards 304.3.1 also calls for a 60 inch turning circle in front of an accessible unit, and 405.2 caps any ramp at a 1:12 slope. If you're placing a roll-off dumpster on the same lot, remember a delivery truck needs about 60 feet of straight clearance behind it, which affects where you put both the dumpster and the toilets. Ground stability matters under ADA 302.1, which requires a firm, slip-resistant surface, so gravel pads beat bare mud on a Greenville job site after rain. If the unit needs to sit in a public right of way anywhere in Greenville, confirm that placement with the city before delivery. That rule was not verified for this page, and it's worth a phone call rather than a guess. Our placement guide covers ground clearance and access in more detail, and the permit requirements page walks through what to ask the city.
Do you need handwashing or extra sanitation gear?
Yes, if workers are mixing paints, coatings, herbicides or insecticides. OSHA 1926.51(f)(1) requires washing facilities specifically for that kind of contaminant exposure, and it's not a general handwashing mandate for every job site. Separately, 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at washing stations. Hand sanitizer alone does not satisfy that rule. OSHA 1926.51(a)(1) also requires an adequate supply of potable water at any place of employment, which is why a handwashing station rental often rides along with a porta potty order on Greenville construction sites. If you're running a food truck or catering setup, check whether a grease interceptor on site needs pumping, since those are serviced once fats, oils, grease and solids reach 25 percent of liquid depth. That's a separate call from restroom service, but worth planning at the same time. For septic-connected properties, a typical residential tank gets pumped every 3 to 5 years depending on tank size and household size, covered on our septic pumping service page.
How far in advance should I book?
Book as soon as you have a headcount and date. Greenville construction jobs can often add a unit within a day or two, but weekend events near Mauldin, 6.9 miles southeast, or Greer, 11.4 miles northeast, fill delivery schedules fast. Call early for holiday weekends.
Do I need a permit for a porta potty in Greenville?
That depends on placement and hasn't been verified for every scenario. If the unit sits on private property clear of the right of way, you're usually fine. Confirm anything near a sidewalk or street with the city directly.
How often does the unit get serviced?
ANSI/PSAI Z4.3 sets a baseline of one visit per week for up to 10 users over 40 hours. Higher headcounts or multi-week jobs need more frequent service. Ask about a custom schedule when you book.
What size dumpster pairs with a construction site rental?
That depends on debris volume and job length. Compare 10 yard, 20 yard and 30 yard options, and check dumpster sizes and dimensions before ordering.
Can Greenville Porta Pros deliver to nearby towns too?
Yes. Greenville Porta Pros delivers to Simpsonville, 14.0 miles southeast, Easley, 14.3 miles west, and City View, 5.5 miles northwest. Check the service areas page for full coverage.
