How many people can a 4 stall restroom trailer handle?
Four stalls comfortably serve mid-size gatherings, think 100 to 150 guests over a few hours, more if it's a work crew using it in shifts rather than a single event crowd. For construction sites, OSHA 1926.51(c) sets the real baseline: one toilet facility for 20 or fewer workers, scaling up from there. A 4 stall unit often clears that ratio for crews up to 60 or so, which is why it shows up on construction site services jobs as often as it does at wedding restroom rental sites. If your headcount runs higher, look at the 8 stall restroom trailer instead, or check how many porta potties do i need before you commit. Smaller jobs might only need a 2 stall restroom trailer or a straightforward standard porta potty rental.
What's inside a 4 stall restroom trailer?
Expect four private stalls, sinks, and climate control in most units, a step up from a deluxe flushable porta potty but built for the same flushable convenience. Handwashing setups follow 29 CFR 1910.141(d)(2), which requires soap and towels or a hand dryer, not just sanitizer, so these trailers are built to that standard rather than around a gel pump. If a stall needs to be accessible, ADA Standards section 404.2.3 calls for a 32 inch clear door opening, and section 304.3.1 requires a 60 inch turning circle inside, so ask about an ADA-configured stall or pair the trailer with a dedicated ADA accessible porta potty unit nearby. Ground needs to be reasonably level and firm, similar to the footing you'd want under a temporary fence rental run, and Mount Pleasant Porta Pros checks that during the site walk. For anything with a kitchen or catering tent nearby, pair the trailer with a handwashing station rental to keep food-prep hands separate from restroom traffic.
Where can a 4 stall restroom trailer be placed in Mount Pleasant?
Placement depends on ground access and how far the delivery truck has to back in; roll-off and trailer deliveries generally need about 60 feet of straight clearance behind the truck, so driveways and tight lots get scouted first. If the trailer will sit near a public sidewalk or street frontage, right-of-way placement needs confirming with the City of Mount Pleasant before delivery day; check porta potty permit requirements and dumpster permit requirements if you're also renting a bin for the same job. Storage of tools or décor alongside the trailer is common at events, and a storage container rental or mobile office trailer rental can sit on the same pad. Crews working sites within Mount Pleasant sometimes coordinate delivery with jobs out toward Sullivan's Island, 5.6 miles southeast, or James Island, 11.7 miles southwest, on the same route. Review the porta potty placement guide for ground and clearance basics before your date locks in.

Do I need a permit for a restroom trailer in Mount Pleasant?
It depends on where it sits. Placement in the public right of way needs confirming with the city before delivery. Private lots and driveways typically don't trigger the same review. Check porta potty permit requirements or ask Mount Pleasant Porta Pros directly when booking.
How long can I rent a 4 stall restroom trailer?
Day, weekend, week and multi-week event rentals are all available, with pricing scaling by duration. A single-day rental starts around 175 dollars; a full week starts near 150 dollars low-end but typically runs higher for a fully serviced unit. See porta potty rental per day for comparison against standard units.
Does the trailer need water and power hookups?
Most units run self-contained with onboard tanks, though some deluxe models want a power connection for climate control. Mount Pleasant Porta Pros can advise onsite whether your unit needs a hookup or runs fully independent for the rental period.
Can a 4 stall trailer be ADA accessible?
Yes, with the right configuration. ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, never fewer than one, and section 403.5.1 calls for a 36 inch clear route to reach it.
How often is the trailer serviced during a multi-day rental?
Servicing follows a standard interval similar to ANSI/PSAI Z4.3 guidance, roughly weekly for lighter use, more often for high-traffic events. Ask about a servicing schedule when you book through request a quote.
