Conditions 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.
Conditions for Events
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.
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 the date falls in a hot spell, add a hand-wash station at each row and ask about an extra service visit.
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. A winter event can still land on one of the few freezing nights; ask about it if your date is in winter.
Outdoor Season
Most of the year suits outdoor events; a summer hot spell or a rare winter freeze are the exceptions to plan around.
Local Settings
For a party at an apartment complex or a rented home, the property manager or landlord decides where units can stand.
How Many Units
The Portable Sanitation Association International (PSAI) chart sizes event restrooms by crowd and hours, assuming no servicing during the event:
| Crowd | 1 hr | 2 hrs | 3 hrs | 4 hrs | 5 hrs | 6 hrs | 7 hrs | 8 hrs |
|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |
| 1,000 | 4 | 6 | 8 | 8 | 9 | 9 | 11 | 12 |
| 2,000 | 5 | 6 | 9 | 12 | 14 | 16 | 18 | 20 |
| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a full-day festival, take 5,000 people over six hours: the chart gives 38 units. If alcohol is served, PSAI adds 10–20%, which is 42 to 46 units after rounding up. For accessibility, 5% of 46 is 2.30, which rounds up to 3 ADA units in a single cluster; split into 2 clusters of 23, each cluster needs its own, so 4 ADA units in total.
Ask about servicing during an all-day event. See the PSAI event chart for the full table.
Placement and Access
Put restroom rows on firm, level ground the service truck can reach, away from food prep, with ADA units on an accessible route and hand-wash stations beside the rows.
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. Grass venues soften after heavy rain; set restroom rows on the firmest, highest ground beside a hard surface the truck can use, and keep the ADA route on pavement or another firm surface.
Who to Ask About Local Rules
Charleston is an incorporated city with its own municipal government. For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, ask the Charleston city government before you book what applies.
Charleston spans Charleston County and Berkeley County; county-run parks and roads follow the county the site is in.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours, and whether it runs over several days
- Whether alcohol or food will be served
- ADA units for every cluster (at least 5%, rounded up) and hand-wash stations
- Firm ground for rows after rain
