Standard porta potty
$125 to $250 a weekend
How many porta potties do I need for a jobsite?
Start with your headcount, then check it against OSHA 1926.51(c)(1): 1 toilet facility for 20 workers or fewer, 1 toilet seat plus 1 urinal per 40 workers once you pass 20, and 1 seat plus 1 urinal per 50 workers at 200 or more. A 15 person framing crew needs one standard porta potty rental. A 60 person site splits into two brackets and needs two seats and two urinals. Most Charlotte contractors also add a wash station, since OSHA 1926.51(a)(1) requires an adequate supply of potable water at every place of employment, separate from the toilet count itself. If your crew is applying paint, coatings, herbicides or insecticides, 1926.51(f)(1) kicks in and you need washing facilities for that exposure specifically, not just a sink for lunch. Check our OSHA portable toilet requirements guide for the full bracket table, or use how many porta potties do I need style math against your own roster before you call for a quote at Charlotte Porta Pros.
How many porta potties do I need for an event?
Event math runs on guest count and hours, not worker brackets. A rough rule: 1 unit per 50 people for a 4 hour event without alcohol, tightening to 1 per 35 to 40 once beer or wine is served, since drinking pushes usage up fast. A 200 guest wedding at 4 hours wants 4 to 5 standard units, or fewer if you upgrade to a deluxe flushable porta potty for the bridal party. Multi-day festivals need the daily count multiplied by service visits, not just added units, since ANSI/PSAI Z4.3 sets a baseline service interval of once per week for up to 10 users over a 40 hour week, a pace far too slow for a weekend crowd. That is why event contracts specify daily or twice daily service instead. See event restroom rental or festival restroom rental for service-frequency planning, and wedding restroom rental if alcohol is on the guest list.
Table: units by headcount and event length
| Guests | 4 hours, no alcohol | 4 hours, with alcohol | 8+ hours or multi-day |
|---|---|---|---|
| 50 | 1 | 2 | 2 |
| 100 | 2 | 3 | 4 |
| 200 | 4 | 5 | 7 |
| 500 | 10 | 13 | 16 |
These are planning ranges, not code minimums. A standard unit runs 100 to 350 dollars a day depending on delivery distance and rental length, and jumps to 200 to 800 dollars for a flat event rate that bundles delivery and pickup. Check porta potty rental cost or porta potty rental per day for the full breakdown before you commit to a headcount.
Do I need an ADA unit?
Yes, if you are clustering multiple single-user units. ADA Standards section 213.2 requires at least 5 percent of a cluster to be accessible, and never fewer than one unit, no matter how small the cluster is. That means even a 3 unit jobsite bank in Charlotte needs one ADA accessible porta potty. The accessible unit itself has to give a 60 inch turning circle per ADA 304.3.1, a 32 inch clear door opening per ADA 404.2.3, and a stable, slip resistant floor per ADA 302.1. Reach ranges for controls follow ADA 308.2.1, capped at 48 inches high and 15 inches low, and door hardware has to open with one hand and no more than 5 pounds of force under ADA 309.4. Weekly ADA rental in Charlotte runs 120 to 240 dollars depending on unit and term; daily rental runs higher per day but lower in total for short jobs. Full spec detail lives on ADA restroom requirements.
How many tons does a 20 yard dumpster hold, and how does that change my count?
A 20 yard dumpster holds roughly 2 to 3 tons of mixed debris and measures about 22 feet long, a footprint that matters when you are siting both a dumpster and a toilet bank on a tight Charlotte lot. Cubic capacity runs around 20 cubic yards, which works out to roughly 540 cubic feet. A 10 yard dumpster, by contrast, is about 12 feet long and holds around 270 cubic feet, so it takes up half the yard footprint. If your renovation crew needs both a 10 yard dumpster rental and a jobsite toilet, plan the dumpster's 60 foot straight clearance requirement behind the delivery truck first, then place your porta potty where it will not block that path. See dumpster sizes and dimensions for the full yard-by-yard comparison, or 20 yard dumpster rental directly.
How many tons can a 30 yard dumpster hold, and a 40 yard?
A 30 yard dumpster typically holds 3 to 4 tons and runs about 22 feet long with roughly 810 cubic feet of capacity, a common size for whole-house cleanouts and roofing tear-offs. A 40 yard dumpster holds around 4 to 5 tons, with roughly 1,080 cubic feet inside, and needs the same 60 foot straight clearance behind the truck for delivery. Bigger jobs with bigger crews mean bigger toilet counts too: a 40 person demolition crew crosses the first OSHA bracket at 20 workers, so you are into the 1 seat plus 1 urinal per 40 range under 1926.51(c)(1), not just a single unit. Weekly dumpster rental in Charlotte runs 426 to 778 dollars depending on size and hauler distance. Compare tonnage and footprint on 30 yard dumpster rental and 40 yard dumpster rental, or check dumpster weight limits before you overload one.
Where can I place units in the Charlotte right-of-way?
Placement in the public right-of-way needs confirming with the city before delivery day. Charlotte's Department of Transportation requires a Right-of-Way Use Permit for construction dumpsters placed in the street or sidewalk, per the CDOT Right-of-Way Use Permit Program brochure, and that same office handles lane closures, sidewalk closures and street crossings. Requests go through an online portal at least 48 hours ahead, though a full street closure needs a minimum of 10 working days lead time. Chapter 19 of the Charlotte Code of Ordinances makes it unlawful to place an unnecessary obstruction, including a tent, table or tarp, in the right-of-way, but whether a standalone porta potty triggers the same permit as a dumpster is not spelled out in any city page we found. If your job sits on a state-maintained road inside Charlotte city limits, NCDOT rather than CDOT may hold jurisdiction, another point worth confirming before delivery. Read porta potty permit requirements and dumpster permit requirements for what is documented so far, and use porta potty placement guide for on-property siting that avoids the permit question entirely.
How long can I keep a rental, and does the count change over time?
Longer jobs do not need more units, usually just more service visits. A single porta john rental on a 6 month renovation still serves the same 20 person crew it served on day one, but it needs cleaning on a fixed schedule instead of a one-time pump. Monthly standard rental in Charlotte runs 125 to 325 dollars, well below the per-day rate stacked out over 30 days, which is why monthly porta potty rental makes sense for any job past a few weeks. Storage needs often ride alongside long jobs too: a 20 foot storage container rental or a 40ft storage container for materials, plus a temporary fence rental around the whole site. For jobs near Charlotte, driving distance affects delivery pricing: Matthews sits 12.2 miles southeast, Huntersville 15.7 miles north, and Fort Mill, SC sits 19.7 miles southwest, all inside typical delivery range from a Charlotte-based fleet.
How many porta potties do I need for a 100 person wedding?
Plan for 2 units without alcohol, 3 with it, over a 4 hour reception. Add a deluxe flushable porta potty or two if the budget allows, since guests notice the upgrade more at weddings than at construction sites.
How many toilets does OSHA require for a 25 person crew?
Under OSHA 1926.51(c)(1), once you pass 20 workers you move into the next bracket: 1 toilet seat and 1 urinal per 40 workers. A 25 person crew still fits in that single bracket, so one seat and one urinal covers it.
How many cubic feet in a 10 yard dumpster?
Around 270 cubic feet, in a footprint roughly 12 feet long. That is enough for a small bathroom remodel or a single-room cleanout, and it pairs well with a home renovation porta potty on the same driveway.
How many cubic feet in a 40 yard dumpster?
Around 1,080 cubic feet, in a unit close to the same 22 foot length as a 30 yard box but taller. It suits full roof tear-offs and large commercial cleanouts, per 40 yard dumpster rental.
Does alcohol really change my porta potty count that much?
Yes. Alcohol increases bathroom trips and shortens the interval between them, which is why event planners tighten the ratio from 1 per 50 guests to closer to 1 per 35 to 40 once a bar opens.
Can I mix unit types instead of renting all standard units?
Yes, and most Charlotte events do. A common mix is standard units for the general guest count, one ADA unit per ADA 213.2, and a restroom trailer rental or luxury restroom trailer for the host party or VIP area.
