Crawl spaces in Folly Beach
Many island homes are raised on pilings and have open or enclosed areas below rather than a classic crawl space. If your home is in a FEMA flood zone, rules limit what can be enclosed below the lowest floor, so ask the pro and your town's floodplain or building office before enclosing or sealing a space under an elevated home.
