Building on the water in Sullivan's Island
Waterfront in Sullivan's Island includes the Intracoastal Waterway and Cove Inlet. Most new docks and additions here are in the state's coastal critical area, so they need an SCDES permit with stamped drawings and adjoining-owner notice (SC Department of Environmental Services, Critical Area Permitting: Minor Activities). Many island and planned communities also have their own architectural review or HOA rules for docks, so check those early.
