New dock construction in Charleston, SC

A typical Lowcountry private dock is a long walkway over the marsh, a fixed pierhead and often a floating dock and lift at the end. Building one means pile driving from a barge, saltwater-grade materials and a state critical-area permit.

What it costs

The parts of a dock

  • Walkway (pier): from high ground to the water, often long in tidal marsh
  • Pierhead: the fixed platform at the end
  • Floating dock and ramp: stays level with your boat as the tide moves
  • Lift: keeps the boat out of the water

Square footage drives the price. BluTide's worked example: a 40 ft × 4 ft walkway plus a 10 × 12 ft pierhead is 280 sq ft (BluTide Marine Construction (Johns Island), Boat Dock Cost in Charleston, SC: 2026 Price Guide).

Permits

New private docks in the coastal critical area need a permit from the SC Department of Environmental Services (formerly DHEC-OCRM). The application fee is $250, or $150 for docks with walkways under 100 ft, and drawings must be stamped by an SC-licensed surveyor, engineer or landscape architect (SC Department of Environmental Services, Critical Area Permitting: Minor Activities). See dock permits.
