Quick answer
Wake County requires a plumbing permit for the installation, extension, relocation, replacement or general repair of any plumbing system, and publishes one exemption: minor repairs or replacements of plumbing fixtures that do not disrupt the original water supply, waste or ventilation system. A second exemption covers replacing a water heater in a one- or two-family dwelling when the energy use rate or thermal input is no greater than the unit being replaced, there is no change in fuel, energy source, location, routing or sizing of venting and piping, and a licensed plumbing contractor does the work to the current North Carolina State Building Code. A licensed plumbing contractor is otherwise required, except for homeowners who own the property and will personally occupy the structure.

How to apply in Wake County
In Wake County, you apply for a residential plumbing permit at your local building department by filing an application that describes the scope of work and site, along with construction documents, before any regulated plumbing installation, alteration, or repair begins. Minor repairs that do not touch piping or fixtures are generally exempt, and once issued the permit only stays valid if work is started within its time limit.
What most plumbing permit applications include:
- For Wake County, a permit is required before any owner or authorized agent constructs, alters, repairs, removes, converts, or replaces a plumbing system regulated by the code (IRC R105.1).
- For Wake County, the application must identify and describe the work, describe the site, state the intended use and occupancy, and be signed by the applicant or an authorized agent (IRC R105.3).

- Minor plumbing repairs, such as clearing a stoppage or removing and resetting a water closet without rearranging pipes or fixtures, are exempt from permit (IRC R105.2).

Inspections and closing out your permit
In Wake County, plumbing inspections are timed to whatever is about to hide the pipe: underground and under-slab piping is checked before concrete covers it, rough-in piping is pressure or water tested before walls close up, and a final inspection checks every fixture and backflow protection once the work is complete.
- In Wake County: piping and equipment placed under a slab or floor must be in place and inspected before any concrete is poured or floor sheathing is installed over it (IRC R109.1.1.1).
- In Wake County: rough plumbing, along with the mechanical, gas, and electrical rough-in, must be inspected prior to covering or concealment and before fixtures or appliances are set (IRC R109.1.2).
- In Wake County: rough drain, waste, and vent (DWV) piping is tested with water, air, or (for plastic piping) a vacuum, and must show no evidence of leakage before it is closed in (IRC P2503.5.1).
- In Wake County: the water-distribution piping is tested and must hold tight under the system's working pressure, or under a 50 psi air test for non-plastic piping, before it is concealed (IRC P2503.7).
- In Wake County: the framing inspection cannot proceed until the plumbing rough inspection, along with the mechanical and electrical rough inspections, has been approved (IRC R109.1.4).
- In Wake County: at the final drainage test, each fixture is filled and then drained, and its traps and fixture connections must prove watertight by visual inspection (IRC P2503.5.2).
- In Wake County: final inspection is made after all work required by the permit is complete, and includes confirming backflow protection, such as vacuum breakers on hose bibbs, is installed (IRC R109.1.6, P2902.4.3).

- How much does a plumbing permit cost in Wake County?
- 'Residential Trade Permit Fee - $75. The $75 permit fee is a single permit fee for electrical, mechanical and plumbing, regardless of number of trades involved. Electrical pole fee is included in the $75 trade fee.'. See the official fee schedule for current amounts.
- Where do you apply for a plumbing permit in Wake County?
- You can apply through the Wake County permit portal or contact the Wake County Permits and Inspections (Planning and Development Services) directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Wake County?
- Under North Carolina law (N.C. Gen. Stat. 87-1(a), 87-1(b)(2), 87-14(a)(1), 160D-1113, 160D-1115): A North Carolina homeowner may pull the permit and do the work. G.S. 87-1(a) reaches general contracting only where the cost of the undertaking is $40,000 or more, and G.S. 87-1(b)(2) then exempts a person who constructs or alters a building on land that person owns, provided the building is intended solely for occupancy by that person and his family after completion and the person complies with G.S. 87-14. There is no outright ban on selling, but there is a look-back that works like one: if the building is not occupied solely by the person and his family for at least 12 months following completion, the statute presumes the person did not intend the building solely for that occupancy, which defeats the exemption. G.S. 87-14(a)(1) requires an owner claiming the exemption to execute a verified affidavit attesting that they own the property, that they will personally superintend and manage all aspects of the construction and will not delegate that duty to anyone unlicensed, and that they will be personally present for all inspections required by the State Building Code unless a licensed architect sealed the plans. The inspector transmits that affidavit to the Licensing Board, and if the Board determines the exemption was not available the building permit is revoked under G.S. 160D-1115. The exemption removes the general contractor license requirement only. It does not exempt the work from permits or inspections, and G.S. 160D-1113 provides that when a permit is held by an owner exempt under 87-1(b)(2), no inspection may be conducted without the owner present unless an architect sealed the plans. Confirm how Wake County applies this before you apply.
