Charleston's climate gives mold plenty to work with. NOAA's 1991–2020 normals put annual rainfall at Charleston International Airport at 52.51 inches, with June through September bringing about half of it, and the SC State Climatology Office reports an August mean relative humidity of 79%. Add tidal flooding, tropical storms and homes raised over crawl spaces, and damp areas under and inside houses are a common concern.

Why location matters for mold
The age of a home, how it sits on its lot and how close it is to the marsh or ocean all affect where moisture builds up. Older homes, like much of James Island's housing, may have original ductwork and crawl spaces that have seen decades of humid summers. Barrier-island homes on Isle of Palms and Folly Beach face storm surge and salt air. Inland, heavy rain events like Debby in 2024 can flood neighborhoods far from the coast.
Within the City of Charleston, work on an existing structure in the Special Flood Hazard Area, including storm-damage repairs and HVAC ductwork replacement, requires a permit according to the city. A company quoting rebuild work should be able to tell you whether a permit applies. This is general information, not legal advice.
