## What renting a porta potty in Charleston is actually like

Charleston is a low-lying port city where the tide, not just the storm, decides where a unit can sit. Three local realities shape almost every Charleston order: tidal flooding that now reaches the city's minor flood level dozens of times a year where it once happened a couple of times, a long hot season averaging more than 60 days at 90 degrees or above, and a spring calendar from the Cooper River Bridge Run to Spoleto Festival USA that runs on City permits filed months ahead. Here is how each one changes what we recommend.

### Why the tide and the heat decide where a Charleston unit sits and how often we service it

Charleston floods on sunny days. The National Weather Service tracks every tide at the Charleston Harbor gauge that reaches the minor flood level of 7.0 feet above mean lower low water, and the count has climbed from 2 in 1970 to 25 in 2000 to 89 in 2019, with roughly 45 to 75 a year since. Storms push it much higher: Hurricane Hugo set the record at 12.52 feet in 1989, Irma reached 9.92 feet in 2017, and a December storm in 2023 pushed the harbor to 9.86 feet without a hurricane at all. On low ground near the marsh, the harbor, or the Ashley and Cooper rivers, we set units on the highest firm ground on the lot, check the tide forecast before delivery and service, and move a unit rather than let a king tide or a storm tide reach it.

The heat is the other constant. The Weather Service's 1991-2020 normals show about 64 days a year at or above 90 degrees at the Charleston airport, with humid air that holds the heat through the evening, and the record is 105. Heat and humidity break waste down fast inside a tank, so on busy jobsites and summer events we treat weekly service as the floor and add mid-week visits for large crews or food vendors. Freezes are rare, averaging about 22 nights a year at or below freezing, but we still protect hand-wash water on the coldest nights.

### Spoleto, the Bridge Run, and a special event permit filed 60 to 120 days ahead

Charleston's event calendar is heaviest in spring. The Cooper River Bridge Run 10K fills the city each April, with its 44th running set for April 3, 2027, and Spoleto Festival USA, founded in 1977, fills Charleston's historic theaters, churches, and outdoor spaces for 17 days and nights from late May into June. Around them sit weddings, festivals, and markets on the peninsula and across the city's parks, most of them on public ground.

Any event on a City street, sidewalk, park, or other city property that affects traffic or needs City services requires a Special Event Permit, and the City sets its deadline by size: 60 days ahead for under 500 people, 90 days for up to 1,000, and 120 days for more than 1,000. Every application needs a detailed site plan and an emergency action plan, and the City's Special Events Committee reviews each one. Put restroom and hand-wash locations on that site plan with a clear, level path to accessible units, then send it to us and we deliver to match, service during multi-day events, and pick up on the schedule your permit sets.

### Placement on a low peninsula and the City of Charleston Street Blocking Permit

Much of Charleston's work is on tight historic lots on the peninsula, where houses sit close to the sidewalk and driveways are rare, and on newer construction off the peninsula in West Ashley, on James Island, and on Daniel Island. On private property with clear truck access, a driveway, a side yard, a fenced jobsite, or a private lot, you generally do not need a permit for a portable toilet. On any lot near the water we also pick the highest ground, since a spot that is dry at low tide can be under water at a king tide.

The street and sidewalk are the City's. The City of Charleston Department of Traffic and Transportation issues Street Blocking Permits through the City's online Customer Self Service portal, covering street closures, meter bags, moving trucks, and dumpsters, and it publishes a dumpster ordinance and a construction parking policy alongside them. There is no permit written specifically for a portable toilet at the curb, so when a unit has to go in the street or on the sidewalk we confirm with Traffic and Transportation which permit applies and coordinate it before delivery. State highways answer to the South Carolina Department of Transportation. A unit can never block a sidewalk, curb ramp, hydrant, or driveway.

## Porta potty rental in Charleston, SC: FAQs

### How much does a porta potty rental cost in Charleston?

A standard portable toilet in Charleston, SC starts at $295 for a weekend rental (up to 7 days) or $345 per month, with 4 service visits included in every 28-day rental. Upgrades: deluxe flushing units run $399/weekend, ADA-accessible units $399/weekend, luxury restroom trailers from $1610/weekend. Every Charleston rate is all-inclusive: delivery, pickup, fuel, and environmental and local fees are built into the one price, so there are no surprise line items. Online orders are $0.39 higher than the phone price; either way, we deliver and service the unit ourselves. Enter your ZIP for your exact Charleston rate.

### How many porta potties do I need for a Charleston jobsite (OSHA)?

OSHA's construction sanitation rule, 29 CFR 1926.51(c)(1), sets the floor: 1 toilet for 20 or fewer workers; 1 toilet seat and 1 urinal per 40 workers from 20 up to 200; and 1 toilet seat and 1 urinal per 50 workers above 200. OSHA also expects a worker to reach a toilet within about a 10-minute walk. On a Charleston jobsite, more than 60 days a year at 90 degrees or above means crews drink and use the unit more than a headcount suggests, so we size above the OSHA minimum, add a hand-wash station at the break area, and keep units on high ground away from tidal flooding. Tell us the crew size and we will size the order to the standard.

### How often should portable toilets be serviced in Charleston?

Our standard monthly rental includes 4 service visits over the 28-day period, roughly weekly. Each visit pumps the tank, sanitizes the interior, and restocks paper, soap, and hand sanitizer. In Charleston that weekly interval is the floor, not the ceiling: the city averages about 64 days a year at 90 degrees or more, and heat and humidity break waste down fast, so busy jobsites and events get a mid-week visit rather than a stretched schedule. On low ground we time visits around the tide forecast, and when a tropical storm threatens we secure or pull units. Service is built into the rate, so compliance never depends on anyone remembering to call.

### Do I need an ADA-accessible unit for my Charleston event?

For an event open to the public, yes. The 2010 ADA Standards for Accessible Design require that at least 5 percent of the single-user portable toilets in each cluster be accessible, with a minimum of one, and each accessible unit is marked with the International Symbol of Accessibility. (Units provided only for construction workers are exempt.) In practice a small Charleston event needs at least one accessible unit; a larger one needs one per every 20 standard units. ADA units in Charleston run $399 for a weekend. The accessible unit has ground-level entry, interior grab bars, and a full wheelchair turning radius, and it needs firm, level ground with a clear approach path. Tell us your guest count and we will build the right ratio in.

### Do I need a permit for a porta potty in Charleston, South Carolina?

On private property with clear truck access, a driveway, a side yard, a fenced jobsite, or a private lot, you generally do not need a permit for a portable toilet in Charleston. The street and sidewalk are different: the City of Charleston Department of Traffic and Transportation issues Street Blocking Permits through the City's online Customer Self Service portal for street closures, meter bags, moving trucks, and dumpsters. There is no permit written specifically for portable toilets, so if your unit has to go curbside or on the sidewalk we confirm with Traffic and Transportation which permit applies and coordinate it before delivery. Events on City streets, sidewalks, or parks need a Special Event Permit filed 60 to 120 days ahead depending on size, and state highways answer to SCDOT. A unit can never block a sidewalk, curb ramp, hydrant, or driveway.

### What is the difference between a standard, deluxe, and restroom trailer in Charleston?

A standard unit is the jobsite and everyday-event workhorse: enclosed, stocked, and cost-effective at $295/weekend. A deluxe flushing unit adds a foot-pump flushing bowl and an in-unit sink for guest-facing events like weddings and corporate functions at $399/weekend. A luxury restroom trailer is a climate-controlled, multi-stall unit with porcelain toilets, running-water sinks, and mirrors, indistinguishable from a fine-venue bathroom, from $1610/weekend. Pick by how guest-facing the site is and how long the rental runs.

### Can I get same-day or weekend porta potty delivery in Charleston?

Yes. We deliver and service portable toilets throughout Charleston and the surrounding Charleston metro area, with same-day and next-day drop-offs available in most of the area when you book early. Weekend event units are delivered clean before your event and picked up after. Enter your ZIP or call (866) 858-3867 and we will confirm the soonest available delivery for your address.

### Do you rent hand-wash stations in Charleston?

Yes. A freestanding hand-wash station pairs with any toilet unit and needs no power or water hookup: it has a foot-pump faucet, soap, and paper towels, stocked at delivery and every service visit. One station serves roughly four toilet units, the ratio most health departments expect. For food and drink events in Charleston, plan a station near the vendors and one near the toilets to cover both inspection points.

### How far ahead do I need a permit for portable toilets at a Charleston event?

For an event on City property, earlier than most people expect. The City of Charleston requires a Special Event Permit for events on public streets, sidewalks, parks, and other city property, and applications are due 60 days ahead for events under 500 people, 90 days ahead for up to 1,000, and 120 days ahead for more than 1,000. Every application needs a detailed site plan and an emergency action plan, and the Special Events Committee reviews each one. Show restroom and hand-wash locations on your site plan, then send it to us and we deliver the right count, with accessible units on a level path. In spring, around the Bridge Run and Spoleto Festival USA, book units early too.
