The state rule
North Carolina General Statute 160D-1110 says no person may begin or proceed with the installation, extension or general repair of any plumbing system without first securing all permits required by the State Building Code and other applicable laws. The permit must be in writing and must require that the work comply with the State Building Code and other state and local laws.
There is one written exception for plumbing: in a one- or two-family dwelling, connecting a replacement water heater does not need a permit when a licensed plumber performs it, personally examines it at completion, ensures the gas piping is leak tested, and the new heater does not exceed the old one's input or change its fuel, location, capacity, or venting and piping. Our water heater page explains those conditions.
Who issues permits in Wake Forest
The Town of Wake Forest Inspections Department provides building inspections and permitting for all areas inside the town's jurisdiction. Its responsibilities include processing applications, plan review, collecting fees and issuing permits, and inspecting construction in phases, including the installation of electrical, plumbing and mechanical systems, and issuing certificates of compliance and occupancy.
The town's permit portal lists residential permit types including a residential plumbing permit, and states that all inspections must be scheduled before 3 p.m. to be done the next day. Properties outside the town's jurisdiction fall under the county or another town, so check which government covers your address before applying.
What usually needs a permit
Using the statute's wording, new plumbing, extensions such as adding a bathroom, and general repairs to the plumbing system require permits. Moving or upsizing a water heater, switching from electric to gas, or changing venting takes a replacement out of the exception. Replacing a pressure reducing valve or a section of supply line is a repair worth asking about.
Exact requirements can depend on the State Building Code and on the town's interpretation, so ask your plumber and, if in doubt, the Inspections Department. A licensed plumber who does permitted work regularly will know the local process; check the license first with our license guide.

The contractor or owner applies through the town's portal, pays the fee, and receives the permit. Inspections are requested as work reaches each stage; the portal notes the 3 p.m. cutoff for next-day inspections. Work that will be covered, such as pipes in walls, is inspected before it is closed up.
Keep the permit number and the final inspection result. They answer questions later from buyers, insurers and lenders. If the work involved digging in the yard, NC 811 locate requests come first; see sewer backups and drain cleaning.
Emergencies and permits
An emergency does not erase the permit rule, but it does change the order of events. Stop the water and protect the house first, as described in our emergency steps, then let the plumber handle the permit for the permanent repair as required.
If an emergency repair is temporary, ask the plumber to explain in writing what the permanent fix will be and whether it needs a permit. For the bill side of an emergency, see our high water bill guide.
