Do I need a permit for water heater replacement in Unincorporated Duplin County?

It depends. Whether water heater replacement needs a permit in Unincorporated Duplin County comes down to the details of your project.

A water heater changeout generally requires a plumbing permit and must be performed by a licensed contractor. A few North Carolina jurisdictions allow a narrow exception for reconnecting an existing electric water heater in the same location at the same or lower capacity, but most require a permit, so confirm with your local department. Switching fuel type, relocating the unit, or altering gas or venting is not covered by any exemption and requires a permit. Duplin County's own permitting office is the Duplin County Building Inspections office, reachable on 910-296-2124 at https://www.duplinnc.gov/182/Building-Inspections. 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. Ask whether a like-for-like swap is exempt at your address, since that answer varies between the county and its municipalities. Under NCGS 160D-1110(a), a one- or two-family home needs no permit to connect a replacement water heater when a contractor licensed under G.S. 87-21 does the work and examines it at completion, a leak test is done on any gas piping, and there is no change in fuel, energy source, location, capacity, input rating, or venting and piping size. Any other water heater job needs a permit from Duplin County Building Inspections. An electric water heater replacement is also exempt from the electrical permit when a licensed electrician connects it to the existing circuit in the same location at the same or lower capacity and rating. In a Special Flood Hazard Area, UDO Section 1119(D) lists hot water heaters among service equipment that must be at or above base flood elevation plus 2 feet when new or part of a substantial improvement.
