Construction seaward of the SC baseline or setback line requires a SC DHEC-OCRM coastal zone permit in addition to Charleston building permits, with strict limits near beaches and tidal marshes.
South Carolina's Beachfront Management Act establishes a baseline and setback line along oceanfront property; construction seaward of the setback requires a permit from SC DHEC's Office of Ocean and Coastal Resource Management (OCRM). Charleston layers local floodplain rules on top, requiring elevation certificates and freeboard above base flood elevation. Tidal marsh critical areas have a 50-foot OCRM buffer. New seawalls along the Battery require both city and state approval. Erosion control on beachfront parcels is heavily regulated.
OCRM fines up to $10,000 per violation per day, mandatory removal of unpermitted structures, and city stop work orders pending state approval.
