North Carolina Plumbing Contractor License Cost & Requirements (2026)
North Carolina licenses its plumbers through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors, a single board that also carries heating and fire sprinkler work and issues 31 different license qualifications. The first thing to unlearn is the ladder: there are no journeyman or master plumbers in North Carolina's system. There are contractor licenses, held by the businesses and their qualifiers, and technician licenses beneath them for the people a contractor lists to do the work.
This page covers the Plumbing Class I contractor license, the unrestricted form, with Class II and the technician license alongside it. It was rebuilt in October 2026 from the board's own applicant information and forms. North Carolina's plumbing fees are flat and modern by the standards of this site: a $150 examination application and a $150 license, $300 in total, on a two-year experience requirement counted as 4,000 hours.

Special Statutory Notes for North Carolina
Licensed by the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G. S. Chapter 87. North Carolina has no journeyman or master ladder: it issues contractor licenses and, beneath them, technician licenses for the contractor's listed workers. Plumbing Class I (P-I) covers plumbing contracting in any building. Class II (P-II) is limited to single-family detached dwellings. A Restricted Limited Plumbing license covers residential work.
Eligibility for the contractor examination requires 2 years (4,000 hours) of on-site, full-time plumbing experience, up to half of which may be academic or technical training, plus a nationwide criminal record report obtained through CastleBranch. The examination, administered by PSI, has a Business & Law portion (1½ hours) and a trade portion (4 hours), is open-book with approved references and requires 70%. The board's examination application fee is $150.
On passing, the license is activated for a $150 fee (halved if you pass after October 1 and activate only for the rest of that year). Licenses expire every December 31. There is no grace period for working on an expired license, renewal in January adds $25, reinstatement is possible within three years, and after three years the examination must be retaken. The board abolished mandatory continuing education in 2012, so none is required.
A technical-examination waiver agreement exists with South Carolina (the North Carolina Business & Law portion must still be passed), and the Neighbor State Licensing Recognition Act may help licensees from Georgia, South Carolina, Tennessee, Virginia and West Virginia who have become North Carolina residents. There is no surety bond for this license.
North Carolina classifies contractor licenses by financial project limits: Limited ($750k), Intermediate ($1.5M), and Unlimited.
Class I, Class II, and the technician beneath
Plumbing Class I (P-I) authorizes plumbing contracting in any building, residential, commercial, industrial or institutional. Plumbing Class II (P-II) limits the holder to single-family detached dwellings. A third, narrower credential, the Restricted Limited Plumbing license, covers residential-scale work including exterior water service and building sewer piping within its size limits. None of them is a rung on the way to another: Class II is a scope choice for firms that only do houses, not a junior license, and its examination is its own.
The technician license is the board's answer to the journeyman question. A plumbing technician works as a listed sub-licensee of a licensed contractor, on potable water and drain, waste and vent systems, without being a contractor; the qualification requires 18 months (3,000 hours) of on-site experience and a $75 license fee.
A technician who later wants the contractor license in the same category and already passed the technical portion needs only the board's Business & Law examination to step up, a genuinely useful bridge the board built into its retest rules.
4,000 hours, a background report, and a two-part exam
Eligibility for the contractor examination requires 2 years (4,000 hours) of on-site, full-time experience in the installation, maintenance, service or repair of plumbing systems, and up to half of it (2,000 hours, equated to 45 quarter hours or 30 semester hours) may come from academic or technical training directly related to the field.
The application also requires a nationwide criminal record report, which every applicant obtains through CastleBranch and attaches to the application; the board states plainly that a record is not an automatic bar, but it is part of every file. The board's posted average for reviewing a complete application is about six weeks.
The examination, administered by PSI, comes in two portions: a Business & Law portion of an hour and a half, required of contractors, and a four-hour trade portion. It is open-book with approved references, scored at 70%, and the board's examination application fee is $150. Passing starts a clock of its own: the license activation form and the $150 license fee are due within 45 days of passing.
Candidates who pass after October 1 may activate for the remainder of the license year at half the fee, or defer activation to January 1 in writing and pay the full fee for the following year, a small courtesy that matters because every license in this board's system turns over on December 31.
December 31, no grace period, and no continuing education
All of this board's licenses expire on December 31 each year, and the board is explicit that there is no grace period for licensed activity after expiration: working on January 2 with an unrenewed license is unlicensed work. Renewal in January itself adds a $25 late charge. A lapsed license can be reinstated within three years by paying the current and prior-year fees and processing charges; beyond three years, the examination must be retaken.
What renewal does not require is continuing education: the board eliminated mandatory continuing education in 2012, so the December renewal is a fee and a form, not a course log. Licensees are still expected to keep up with the North Carolina Plumbing Code as it changes; the board simply does not audit hours for it.
For out-of-state plumbers, two doors exist. The board holds a technical examination waiver agreement with South Carolina, under which the technical portion may be waived while the North Carolina Business & Law portion must still be passed. And the Neighbor State Licensing Recognition Act may qualify North Carolina residents who hold licenses in Georgia, South Carolina, Tennessee, Virginia or West Virginia for equivalent licensure. There is no surety bond for this license at any point in the process.
Mistakes that delay a North Carolina Plumber application
- Looking for a journeyman or master license: North Carolina does not issue them. The rungs are technician and contractor.
- Working in January on an expired license: expiry is December 31 and the board allows no grace period for licensed activity.
- Missing the 45-day activation window after passing: the license is not live until the activation form and $150 fee are filed.
- Taking Class II and then a commercial job: Class II is single-family detached dwellings only, however small the commercial job is.
- Budgeting for continuing education that does not exist, or skipping the background report that does: CE was abolished in 2012; the CastleBranch report is required with the application.
- Assuming a technician can contract: a technician is a sub-licensee of a licensed contractor and cannot contract in their own right until they add the contractor license, for which the Business & Law examination is the bridge.
North Carolina Plumber Licensing FAQ
What does a North Carolina plumbing contractor license cost in total?

What is the difference between Plumbing Class I and Class II in North Carolina?
Scope of buildings. Class I (P-I) covers plumbing contracting in any building: residential, commercial, industrial and institutional. Class II (P-II) is limited to single-family detached dwellings.

How much experience does a North Carolina plumber need?
For the contractor examination, 2 years (4,000 hours) of on-site, full-time experience installing, maintaining, servicing or repairing plumbing systems, with up to half (2,000 hours) creditable from directly related academic or technical training. The technician license requires 18 months (3,000 hours). Experience counts whether or not a license was legally required for the work performed.

No. The board eliminated mandatory continuing education in 2012, for plumbing and heating licenses alike. Renewal is an annual fee ($150 by December 31) and a form.
