What is the difference between a finished basement and an ADU in Folly Beach?

A finished basement is simply extra living space within the main home, while an ADU in Folly Beach is a legally separate dwelling unit with its own kitchen, bathroom, and entrance that meets the town's specific zoning and permitting requirements. That distinction matters because only a properly permitted ADU can be rented out as a separate unit or counted as additional living space by an appraiser. Brian Beatty can help a Folly Beach owner figure out which category their space actually falls into before listing it either way.
