Do I need a permit for plumbing fixture or repiping in North Charleston?
Yes. In South Carolina, plumbing fixture or repiping generally requires a permit, and North Charleston 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 a North Charleston home requires a plumbing permit filed through the Customer Portal, since changing the plumbing system is regulated under the adopted 2021 International Plumbing Code. Rough-in must be inspected before the walls are closed up, so schedule the plumbing inspection through your portal before drywall or finishes go back in. For a home in a special flood hazard area, repiping can count toward FEMA substantial improvement rules, so confirm scope with the Building Inspection Department at 843-740-2562.
