How to check a plumber's license in North Carolina
To check a plumber's license in North Carolina, search the person's or company's name, or the license number, in the Verify License Search of the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. That board is the official record. Its consumer guidance says anyone who contracts to install, alter, or restore plumbing must hold its license, while minor repairs and service work do not require a state license.
Which license fits the job
A license only covers the work its class names. These definitions are quoted from the board's contractor license definitions:
| License | What it covers |
|---|---|
| P-I (Plumbing Class I) | Potable water and drain/waste/vent piping systems in any building (residential, commercial, industrial) |
| P-II (Plumbing Class II) | Potable water and drain/waste/vent piping systems in single-family detached dwellings only |
| LWH (Limited Plumbing Water Heater Replacement) | Replacement of a water heater in a single-family detached dwelling in the same location |
| RLP (Restricted Limited Plumbing) | Exterior building sewer piping, exterior water service piping 2" or less, exterior backflow preventers on 2" or less piping, and water filtration systems |
| FP (Fuel Piping) | Fuel gas piping from an approved fuel source to any system, equipment, or appliance inside the premises |
So a P-II license fits a single-family house but not a townhouse building or a shop, and an LWH license covers a like-for-like water heater swap but not a move to a new location. Gas piping needs fuel piping privileges; the board's applicant information says these are included in the plumbing and heating licenses.
Before you hire
The board's consumer guidance lists what to check:
- The contractor has the appropriate license, if one is required.
- The contractor has liability insurance and workers' compensation, if required.
- You have at least three estimates, and you do not automatically accept the lowest.
- You can reach previous customers, and the contractor has a permanent business location and phone number you have verified.
For a water heater swap, also ask who pulls the permit. Mecklenburg County's permit guidance puts the responsibility for permits on the homeowner, whether you do the work or hire a contractor. What a typical visit costs is in the plumber cost guide.
If something goes wrong
The board's guidance says you can file a written complaint with the licensing board, and with your local Better Business Bureau and the Consumer Protection Section of the North Carolina Department of Justice (919-733-7741). The board itself is reachable at 919-875-3612.
Questions about plumbing licenses in North Carolina
Are the license lookup sites in search results the official record?
No, the official record is the state board's own Verify License Search. Third-party lookup sites copy or summarize it and can be out of date.
Does every plumbing repair need a state license?
No, the board's guidance says minor repairs and service work to plumbing systems do not require a state license. Installing, altering, or restoring plumbing under a contract does.
Can a P-II plumber work on my townhouse?
No, the board defines P-II as covering single-family detached dwellings only. A building with more than one unit needs a P-I license.
