Charleston at a Glance
Climate figures: NOAA 1991–2020 normals from the Charleston City, SC station, about 4 miles away. Snowfall is from the Charleston Intl Ap, SC station, about 6 miles away.
Planning Around the Weather
DOE's Building America map puts Charleston County in the Hot-Humid climate region (IECC 2021 zone 3A, PNNL county guide). This region pairs heat with humidity for much of the year; for long rentals in the hot months, ask how often units will be serviced.
Rain and Ground
Heavy rain days are frequent: about 12 days a year bring an inch or more of precipitation, out of about 44 inches in total. Soft ground is the risk: units belong on a firm, level base the service truck can reach without crossing a soggy lawn, and an ADA unit needs a route that does not turn to mud.
Summer Hot Spells
About 25 days a year reach 90°F, fewer than most U.S. places in our data; hot spells come and go rather than lasting all summer. If your dates land in a hot spell, ask for an extra service visit on multi-day rentals and keep hand-wash stations topped up.
Occasional Freezes
Only about 6 nights a year reach 32°F (fewer than three in four U.S. places in our data), but one hard freeze is enough to damage anything that holds water. For winter dates, ask what the provider does with water-carrying units when a freeze is forecast.
Job Sites and Home Projects
New Housing
About 26.3% of Charleston's housing units were built in 2010 or later (ACS 2020–2024), about 2.3 times the U.S. share of 11.4% and higher than nine in ten U.S. places in our data. Projects that build in phases can move units as each phase finishes; ask for relocation as a service visit when you book.
Apartments, Townhouses and Rentals
The most common housing type is detached houses, about 48% of units (lower than three in four U.S. places in our data), followed by buildings with five or more units at about 36% (ACS 2020–2024). Apartment and condo projects bring larger crews, and a property manager decides where units go. About 44% of occupied homes are rented (owner share lower than three in four U.S. places in our data), so check who controls the property before a unit goes on it.
OSHA 29 CFR 1926.51 scales with headcount: 45 workers on an apartment or condo site need 2 toilet seats and 2 urinals, 210 need 5 of each. More on sizing: job-site porta potties in Charleston.
Events, Weddings and Parties
An all-day festival for 5,000 people over six hours needs 38 units on the PSAI event chart, or 42 to 46 with alcohol (PSAI adds 10–20%). Every cluster of restrooms needs at least 5% accessible units, rounded up, and with heavy rain this common the ADA unit needs a route that stays firm when the grass is wet.
Temperatures rarely get in the way here; rain does, so a restroom trailer needs a pad that will still hold its tow vehicle after a storm. For a party at an apartment complex or a rented home, the property manager or landlord decides where units can stand. More: event restrooms in Charleston and wedding restroom options.
Who to Ask About Local Rules
