Do I need a permit for plumbing fixture or repiping in Isle of Palms?
Yes. In South Carolina, plumbing fixture or repiping generally requires a permit, and Isle of Palms is no exception.
A whole-house repipe requires a plumbing permit and a pressure test while the piping is still exposed. Do not close up walls before that rough inspection passes. Approved piping materials and any backflow protection are checked at inspection, so confirm the accepted materials with the building department before buying. Repiping the water or drain lines in an Isle of Palms home requires a Plumbing and Gas Permit, since changing the plumbing system is regulated under the adopted 2021 South Carolina Plumbing Code. Rough-in must be inspected before the walls are closed up, so schedule the plumbing inspection before drywall or finishes go back in. For a home in the Special Flood Hazard Area, extensive repiping can count toward the city's cumulative 50 percent substantial improvement threshold, so confirm scope with the Building and Planning Department at 843-886-9912.
