Quick answer
Raleigh issues its own plumbing permits, and its How to Get a Residential Permit chart lists existing water and sewer line replacement and water heater replacement among projects that need a permit but no plans. North Carolina law exempts the connection of a replacement water heater in a one- or two-family dwelling when a licensed plumber (G.S. 87-21) inspects the work and leak-tests the gas piping and nothing about the fuel, energy source, location, capacity or venting changes. It also exempts plumbing replacements costing $40,000 or less in a single-family residence that do not change size or capacity; any addition or redesign of plumbing needs a permit.

How to apply in Raleigh
In Raleigh, 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 Raleigh, 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 Raleigh, 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).
- Two or more sets of construction documents must accompany the application, drawn with enough clarity to show the location, nature, and extent of the proposed plumbing work and how it will conform to code (IRC R106.1, R106.1.1).
- 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).
- Once issued, a permit is only valid for a limited window, commonly 180 days, and becomes invalid if the work is not started or is abandoned within that time, though extensions can be requested (IRC R105.3.2, R105.5).

Inspections and closing out your permit
In Raleigh, 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 Raleigh: 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 Raleigh: 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 Raleigh: 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 Raleigh: 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 Raleigh: 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 Raleigh: 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 Raleigh: 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).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Raleigh permit portal or by phone at 919-996-2500.

- Where do you apply for a plumbing permit in Raleigh?
- You can apply through the Raleigh permit portal or contact the City of Raleigh Planning and Development Department (Permits - Residential; Planning and Development Customer Service Center) directly. The links are listed on this page.
- Can a homeowner pull a plumbing permit themselves in Raleigh?
- 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.
