Wilmington, NC Building Safety: Plumbing Permits (2026)

Section 18-50 of the Wilmington City Code covers more than plumbing: it requires a permit for construction, plumbing, HVAC, electrical work, sign installation, and any change of building use, but the plumbing clause is explicit on its own terms. Subsection (a)(2) bars anyone from proceeding with the installation, extension, or general repair of any plumbing system without first applying for and receiving a permit from the city manager or designee and, where the county inspections department has jurisdiction, from that office as well. The permit officer will not sign off unless the plans, specifications, and intended use conform in all respects to the chapter, and the city manager can require whatever supporting information he lawfully needs to evaluate the application, per subsection (c).

Projects that fall within a coastal area of environmental concern face an added layer: subsection (d) requires the application to state the location of the area of environmental concern, and subsection (e) makes the county engineer, acting as the CAMA permit officer under the joint New Hanover County/Wilmington Coastal Area Management Act Implementation and Enforcement Plan, certify compliance with state guidelines before the city issues the permit. A permit denial or an administrative dispute over the plumbing plan goes to the board of adjustment for review or variance under subsection (b).

Once a permit issues, § 18-53 lets the city withhold, condition, or revoke it if the work departs substantially from the approved plans, was obtained by false representation, or otherwise violates the chapter, and the city can stop work outright under its state building code authority.
