Wayne County, NC Building Safety: Plumbing Permits (2026)

Section 14-21 adopts the North Carolina State Building Code by reference for safe design, construction methods and materials, and Section 14-22 separately adopts the North Carolina Plumbing Code, as published and amended by the North Carolina Building Code Council, in full as though printed in the county code. Section 14-27(b) requires every building or structure meant for human habitation, occupancy or use to have its plumbing, plumbing systems and fixtures installed, altered, extended, repaired or reconstructed according to that Plumbing Code's minimum standards. Section 14-92(c) is the operative permit rule: no person may commence or proceed with installing, extending or generally repairing any plumbing system without a written permit from the plumbing inspector, though minor repairs or replacements on the house side of a trap are exempt as long as they do not disrupt the original water supply or the waste or ventilating system.

A plumbing contractor must first register with the inspection department under Section 14-91, giving name and place of business, before pulling permits. Detailed plans and specifications must accompany the application whenever the estimated total cost of the building exceeds $30,000, per Section 14-94. Permits expire automatically six months after issuance if work has not begun, and expire immediately if started work is discontinued for 12 months, under Section 14-98. Permit fees are based on the total estimated cost of the work and are set by the board of commissioners under Section 14-100.
