Do I need a permit for plumbing fixture or repiping in Wilmington?
Yes. In North Carolina, plumbing fixture or repiping generally requires a permit, and Wilmington is no exception.
Repiping a home is plumbing work and requires a permit; it is never covered by the NCGS 160D-1110 minor-work exemption regardless of cost. If walls are opened and re-closed, the framing patch and insulation may need to be inspected before cover; confirm the inspection sequence with your local department. Inside Wilmington city limits the building permit comes from New Hanover County Permits and Inspections, not from the city. The City of Wilmington Zoning team reviews and approves first, so the order matters: verify zoning with the city at 910-254-0900 or zoning@wilmingtonnc.gov, then apply to the county through the COAST online permit portal at 910-798-7308. Schedule the rough inspection with New Hanover County through the COAST portal before walls are closed. Plumbing work is an express exception to the North Carolina $40,000 permit exemption under NCGS 160D-1110(c), so a repipe needs a plumbing permit regardless of cost. The rough inspection has to happen before walls are closed up. New Hanover County's own permitting office is the New Hanover County Building Safety Department, reachable on 910-798-7308 at https://www.nhcgov.com/202/Building-Safety. Its online permit portal is https://newhanovercountync-energovpub.tylerhost.net/apps/selfservice. It issues permits for the unincorporated county. If your city does not run its own building department, this is the office that will handle the job, and that is more common in North Carolina than most states: the county is often the building authority even inside city limits, with the city handling only zoning. The rough inspection has to happen before walls are closed, so confirm scheduling lead time when you pull the permit.
