How many units do I actually need?
Start with headcount, not guesswork. Our guide on how many porta potties you need breaks it down by hours and drink service, but the baseline for construction sites comes from OSHA 1926.51(c): one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass 20. Agricultural crews follow a different rule, OSHA 1928.110, which calls for one facility per 20 hand-labor employees within a quarter mile walk. For weddings and private parties, check the wedding restroom rental page for ratios that account for guests in formal wear who won't wait in line. Tamiami sites near Sweetwater, 3.1 miles northeast, sometimes pull crews from both towns, so count everyone actually on site that day, not just your core crew. If you're running a mixed job with framers one week and painters the next, revisit the count each phase. A standard porta potty rental covers most job sites, while events lean toward the deluxe flushable porta potty for guest comfort.
Do I need an ADA unit?
Yes, if you're clustering multiple units. ADA Standards section 213.2 requires at least 5 percent of a cluster to be accessible, and never fewer than one unit, even if your math rounds down. An ADA accessible porta potty needs the clearances too: ADA 403.5.1 sets a 36 inch minimum route width, ADA 404.2.3 sets a 32 inch door opening, and ADA 304.3.1 calls for a 60 inch turning circle inside. Check the ground under the pad as well. ADA 302.1 requires the surface to be stable, firm and slip resistant, which rules out loose gravel or soft turf in Tamiami's sandier lots. Grab bars and controls need to meet ADA 309.4, operable with one hand and no more than 5 pounds of force. Skip this step on a public event and you're exposed if someone challenges access. Full detail lives on our ADA restroom requirements page, and the event restroom rental page covers how ADA units fit into a broader event layout.
Where should units go on site?
Put them on flat, stable ground with truck access, full stop. A roll-off or restroom trailer delivery needs about 60 feet of straight clearance behind the truck, so measure your driveway or lot entrance before delivery day, not after the driver arrives. Standard units run about 44 by 48 inches on the ground and stand roughly 92 inches tall, small enough for tight yards but still needing a level pad. If you're near a curb or the public right of way in Tamiami, placement there needs confirming with the city before you commit to a spot. Our porta potty placement guide walks through sightlines, drainage and distance from food service. Lighting matters after dark: OSHA 1926.56(a) sets minimum illumination for construction areas, so pair units with a light tower rental on multi-day builds. If the site sits near Westchester, 4.4 miles east, or Kendale Lakes, 4.6 miles south, tell your dispatcher the cross streets so the driver doesn't guess.
What else belongs on the checklist?
Water, handwashing and waste flow all need a plan before delivery day. OSHA 1926.51(a)(1) requires an adequate supply of potable water at every place of employment, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not sanitizer alone. If your crew is spraying paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in and you need washing facilities on site for that work specifically. Pair your toilets with a handwashing station rental or a portable sink rental to cover both rules at once. Service interval matters too: ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users over a 40 hour week, so a bigger crew or longer hours means more frequent pumping. If you're running a septic system on site instead of rentals, a residential tank typically needs pumping every 3 to 5 years depending on size and household load, covered on our septic pumping service page. Add temporary fencing around units on public jobs to keep foot traffic controlled, and check dumpster permit requirements if you're pairing a roll-off with your restroom order.
Standard vs ADA vs Deluxe: quick comparison
| unit | day rate | week rate | best for |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | job sites, basic events |
| ada | $200-$400 | $200-$400 | public events, cluster compliance |
| deluxe | $85-$1200 | $150-$290 | weddings, upscale gatherings |
Rates above sit inside typical Tamiami market bands. Delivery runs separately; check porta potty rental cost for how delivery fees stack with unit price, and monthly porta potty rental if your job runs long.
How far in advance should I book?
Book two to three weeks out for events, sooner for holiday weekends. Job sites with ongoing work can often get next-day delivery. If you need something faster, our emergency porta potty rental page covers same-day options for Tamiami and nearby areas.
Do porta potties need a permit in Tamiami?
Permit rules vary by property type and placement, and city confirmation is needed before you place a unit in the public right of way. See porta potty permit requirements for what to ask your local office before delivery.
How often are units cleaned during a rental?
Standard service follows a weekly baseline under ANSI/PSAI Z4.3 for lighter use, but high-traffic events need more frequent visits. Full detail is on how often are porta potties cleaned.
Can I rent just one unit for a small backyard party?
Yes. A single standard porta potty rental covers small gatherings under about 25 guests for a day rate. Add a handwashing station if you're serving food.
What's the difference between a porta potty and a restroom trailer?
A porta potty is a single stand-alone unit; a restroom trailer rental has multiple stalls, running water and interior lighting. Trailers suit weddings and multi-day events better than stand-alone units.
