North Carolina · Plumbing licensing · official-source guide
North Carolina licenses plumbing through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors in Raleigh. An individual passes the examination and the license is then listed in the name of the contracting business, so it operates as a business license held through a qualified person. Plumbing Class I covers all structures, Class II only detached single family homes. Expect 4,000 hours.

North Carolina licenses plumbing at state level through one board, and it is not the general contractor board. The North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors sits at 1109 Dresser Court in Raleigh, on 919-875-3612, with email to information@nclicensing.org. Its office hours are Monday to Friday, 8:00 to 12:00 and 12:30 to 4:00, closed daily for lunch. The board licenses four contracting trades: plumbing, HVAC, fuel gas piping and fire sprinkler contracting. Two bodies of law sit behind it. The statute is Chapter 87, Article 2 of the North Carolina General Statutes. The rules are 21 NCAC Chapter 50, published in full by the Office of Administrative Hearings and linked from the board's own laws and rules page rule by rule. Section 87-21(a)(5) defines a contractor as any person, firm or corporation who for a valuable consideration verifies, inspects, evaluates, tests, installs, alters or restores plumbing, heating or fire sprinklers as defined in the Article, and it reaches installation work on property intended for sale or rental even where no separate payment changes hands. Rule 21 NCAC 50 .0510 states the requirement plainly: an individual may not perform work within the scope of those statutory definitions unless the board has issued the appropriate license, subject to the exemptions in 87-21(c), 87-21(c1) and 87-25.

North Carolina is one of the states where the answer to who is licensed is genuinely two part, and getting it wrong costs a company its ability to contract. An individual sits the examination and qualifies. The license is then listed in the name of the business through which the work is sold. Section 87-26 allows a license to be issued where one or more officers, or a full time employee or employees with authority to act for the corporation, are licensed, and section 87-26(e) requires that persons licensed shall exercise general supervision over contracts to completion. Rule 21 NCAC 50 .0407 sets the mechanics: licenses must be listed in the name in which the holders conduct business, licenses may be issued to corporations, partnerships, governmental agencies, educational institutions or businesses trading under a name, and the license number belongs to the first listed licensee. Adding a second qualified person to a company license is a sub-licensee filing. Removing one is a notification duty: when a licensee leaves an entity, both parties must notify the board within 30 days. A previously licensed individual whose license expired less than three years ago can be added back to an active license on request and payment. In practice the company is the licensed unit a customer sees, and the qualified individual is the reason it exists. Lose that individual without replacing them and the company loses the license.

The statutory split is by scope of structure, not by size of job. Section 87-21(b)(1) sets Class I as covering all plumbing, heating and fire sprinkler systems for all structures, and Class II as covering plumbing and heating systems in single-family detached residential dwellings. So Class II is a residential license in the strict sense, tied to detached single family homes, and Class I is everything. On the board's own examination application the plumbing and heating classifications a candidate can apply for are Plumbing Class I, Plumbing Class II, Heating Group 1 Class I, Heating Group 1 Class II, Heating Group 2, Heating Group 3 Class I, Heating Group 3 Class II, Restricted Limited Plumbing and Fuel Piping. Two narrower plumbing credentials are worth knowing because they change what a small operator can legally sell. The Restricted Limited Plumbing Contractor license is its own classification with its own experience bar. Newer still is the Limited Plumbing Water Heater Replacement Contractor License at 21 NCAC 50 .0521, which lets a person without a plumbing contractor license replace potable water heaters in a single family detached residential dwelling. Its limits are tight: installation in the same area as the water heater being replaced, no more than 10 lineal feet of water distribution piping for the connections, and no installation of recirculating loop piping, with reconnection to an existing loop allowed only inside that 10 foot limit.
Alongside contractor licenses the board issues technician licenses, and contractors misread them regularly. The board's applicant information page lists Plumbing and Heating Technician in Class I and Class II for people employed by contractors or firms, State and Local Government Technician, Private Educational Institution Technician, Fuel Piping Technician in Class I and Class II, Fire Sprinkler Inspection Technician and Fire Sprinkler Maintenance Technician. A technician license is an employment credential, not a licence to sell work. Rule 21 NCAC 50 .0403(c) is explicit: a technician licensed by this Board shall not contract work based on the technician license. The same rule bars a licensed contractor or technician from permitting the use of his license by any other person, and bars bidding on work requiring qualifications the licensee does not hold except through a documented joint venture or the specific contract scenarios under G.S. 143-129. The fee structure reflects the difference in standing. Under 21 NCAC 50 .1102 a plumbing, heating or fuel piping technician working under a contractor pays $75.00 a year, while the contractor classifications sit at $150.00. The board's license activation form shows the same split with one twist: a technician license costs $75 unless the technician is the qualifier for a state or local government entity, in which case it is $150. Hire technicians to do work. Keep a contractor licensee to sell it.

North Carolina counts experience in hours, publishes the numbers, and allows half of them to be earned in a classroom. For a plumbing or heating contractor license the requirement is two years, stated as 4,000 hours, of on-site full time experience, and up to half of that, 2,000 hours, may be academic or technical training. That half and half rule is the single most useful fact for anyone deciding whether a community college programme is worth the time, because it converts directly into a year off the field requirement. The narrower classifications scale down. A Fuel Piping Contractor needs one year, stated as 2,000 hours, with up to 1,000 hours substitutable. A Restricted Limited Plumbing Contractor needs nine months, stated as 1,500 hours, with up to 750 hours substitutable. Technician licenses have their own bars: Class I technician at 18 months or 3,000 hours, Class II technician at 15 months or 2,500 hours, and Fuel Piping Technician at nine months or 1,500 hours. A Fire Sprinkler Maintenance Technician needs one year, 2,000 hours, as a full time maintenance employee, and the fire sprinkler installation and inspection contractor licenses run on current NICET certification instead of raw hours. The board states that its published outline may not be inclusive of every eligibility requirement and directs applicants to the examination application form and the laws and rules book.
North Carolina runs a comparatively accessible exam and then puts two deadlines around it. The passing grade is fixed by rule. 21 NCAC 50 .0305 provides that examinations given by the board are based upon a maximum obtainable grade of 100 points and a grade of 70 is required to pass. Testing is not a once a quarter event. The board states that examinations are given on a daily basis at seven testing centers throughout the state, in Asheville, Charlotte, Winston-Salem, Raleigh, Fayetteville, Greenville and Wilmington. The exam is a reference exam rather than a memory exam: examinees must bring all allowed reference materials to the testing center, which changes how you prepare, because tabbing and indexing the code books is the work. Now the deadlines. An approved candidate must take the exam within ninety days of the notification date. A failing applicant must wait 90 days before retesting. And after passing there is a third clock that catches people: under 21 NCAC 50 .1101(c) the license fee must be paid within 45 days of passing the exam, and the board's own license activation form repeats that the form is due within 45 days of passing the exam or you must re-test. Candidates who pass after November 1 may defer licensure to the following year.

The fees sit in two rules and the board's forms repeat them. Under 21 NCAC 50 .1101(c) an application for a license by examination requires a fee of one hundred fifty dollars ($150.00), made up of a $75.00 application fee and a $75.00 examination fee, and the examination portion is nonrefundable. The board's plumbing, heating and fuel piping examination application states the same total as $150 per exam, payable by check or money order, with a $30 application fee for military veterans and military spouses. Two transfer fees appear in the same rule at $25.00 each: one to reissue or transfer a license to a different corporation, partnership or individual name, and one to issue or transfer a license to the license of an existing licensee. The board's trade name change form and add sub-licensee form both carry $25. Annual license fees are in 21 NCAC 50 .1102. A plumbing, heating or fuel piping contractor pays $150.00. A restricted limited plumbing contractor pays $150.00. Each fire sprinkler classification is $150.00. A plumbing, heating or fuel piping technician under a contractor pays $75.00, and a second or subsequent individual listed on a business license pays $75.00 a year. An initial application without examination is $30.00, and a qualified full time local government inspector pays $25.00. The statute caps these: section 87-22 limits the annual plumbing and heating license to $150.00 and section 87-22.1 caps the examination fee at $150.00.

This is where North Carolina differs from most states a plumbing contractor will have worked in, and it is worth being precise rather than reassuring. Chapter 87, Article 2 contains no surety bond requirement for plumbing, heating or fire sprinkler contractors. The only bond in the Article is at section 87-18, which requires the board's own secretary and treasurer to give bond approved by the board for the performance of their duties, which has nothing to do with licensees. The Article also sets no general liability insurance minimum and no workers compensation coverage figure for licensure. The board's fee rules, its examination application and its license activation form are silent on insurance and bonding as well. So the state floor here is competence and examination, not capital. Do not read that as permission to go bare. Three other layers will set your real numbers. General contractors will set insurance limits in their subcontract agreements. Local permitting offices and utilities set their own conditions for particular work, and Raleigh, for instance, requires any contractor performing construction and repair work in the public right-of-way to provide a Certificate of Eligibility and a bond of up to $5,000.00. And customers increasingly ask before they sign. The absence of a state minimum shifts the question from what must I carry to what will I be asked to show.

North Carolina renews annually and the board is blunt about the deadline. Licenses expire on the last day of December in each year. The board states there is no grace period and that licensees must stop all licensed activities until renewal occurs. A licence that lapses on 1 January is a licence you cannot contract under on 2 January. Late renewal is priced by statute: under section 87-22 the board shall increase the license fee by twenty-five dollars ($25.00). Reinstatement for a longer lapse is more expensive again, requiring payment of the current license fee, the license fee for the unpaid prior years, and a processing fee. Then there is the hard stop. If a license is not renewed within three years after expiration, the board requires reexamination. That is the full examination again, at the $150.00 fee, with all the scheduling that goes with it. The board has published a catch up window for licenses that expired in 2023 through 2025, stating that those renewals must occur before December 31, 2026. On continuing education, North Carolina is unusual and the board says so directly on its education page: mandatory continuing education was eliminated by the board in 2012 and is no longer required in order to renew licenses annually. The board encourages voluntary course work to stay current with codes and practices, but nothing is required at renewal.
A North Carolina plumbing license is not a document you rent out or park. Rule 21 NCAC 50 .0404, Active Employment, requires that at least one individual holding a contractor license in the classification required for the work being proposed or performed be present, and it applies to any business location where licensed work is solicited, negotiated or performed. Note the three verbs: soliciting and negotiating count, not only performing. A branch office that quotes work needs the qualification behind it. The same rule requires the licensed individual to exercise general supervision of all work falling within the license qualification, and it closes the obvious gap by providing that a licensee cannot use their license to qualify a firm during the hours the licensee is committed or active in employment elsewhere. A day job elsewhere and a qualifying role here do not coexist during the same hours. Fuel piping installations carry a further condition, requiring employment of a full time employee holding the appropriate fuel piping license. Rule 21 NCAC 50 .0505 sets the general supervision and standard of competence expectation, and section 87-26(e) makes supervision to completion a statutory duty rather than a courtesy. Rule 21 NCAC 50 .0403(a) completes the picture: a licensed contractor or technician shall not permit the use of his license by any other person. Renting a license is the fastest way to lose one.

North Carolina does not publish a standing list of states whose plumbing licenses it accepts, and the rule explains why. 21 NCAC 50 .0310 provides that the board shall grant license by reciprocity only pursuant to reciprocal licensing agreements worked out with various states after mutual review of the applicable licensing standards and examinations. The rule names no state and sets no automatic qualification. Reciprocity here is a state to state instrument, not a personal right. The statute gives the board a second and wider door. Section 87-21(g) provides that the board may, in its discretion, grant to plumbing, heating or fire sprinkler contractors licensed by other states a license of the same or equivalent classification without written examination upon receipt of satisfactory proof that the qualifications of such applicants are substantially equivalent. Read the two together and the practical route is clear. An out of state plumbing contractor applies and asks the board to exercise its discretion, supported by proof that the other state's standards and examination are substantially equivalent to North Carolina's. That is an evidence exercise, not a form. Gather the other state's licence, its examination scope, and your experience record before approaching the board, and treat the examination route as the fallback. The examination is available daily at seven centers, so the fallback is not a long delay.
Section 87-25 makes it a Class 2 misdemeanor to engage in or offer to engage in the business of plumbing, heating or fire sprinkler contracting without first having been licensed. Offering counts, which means an unlicensed bid is an offence before any pipe is touched. Section 87-25.1 gives the board a civil route as well: it may apply to the superior court for a restraining order and injunction, and recover a reasonable attorney's fee not to exceed five thousand dollars ($5,000) plus costs. The exemptions are narrower than people assume. Section 87-21(c) exempts those who clean plumbing drains and those who make minor repairs or minor replacements to an already installed system, defining minor work as replacement of parts which do not require any change in energy source, fuel type, or routing or sizing of venting or piping. Rule 21 NCAC 50 .0506 then removes the most commonly claimed example: the initial installation or the subsequent replacement of any water heater in any structure requires a license in plumbing, unless personally installed by an owner in non-commercial property. The same rule states that water purification systems interrupting a potable supply are not minor, that work risking water contamination is not minor, that work risking fire, carbon monoxide or sewage exposure is not minor, and that licensed plumbers must install pumps and well seals and perform well disinfection. The board takes complaints through its complaint information page.

North Carolina's display duty is one sentence and it is exact. Section 87-21(e) provides that the current license issued in accordance with the provisions of this Article shall be posted in the business location of the licensee, and its number shall appear on all proposals or contracts and requests for permits issued by municipalities. Three obligations sit in it. Post the physical current license at the business location. Put the number on every proposal or contract. Put it on every municipal permit request. A search of the Article for the words advertise, advertisement, advertising, sign, vehicle, listing and telephone returns nothing, so North Carolina does not impose a statutory truck lettering or paid advertising rule the way some states do. What the rules regulate instead is naming and lending. 21 NCAC 50 .0407 requires licenses to be listed in the name in which the holders conduct business, and puts a $25 trade name change filing behind any change to that name, so the name on your van and the name on the license must match. 21 NCAC 50 .0403(a) bars permitting the use of your license by any other person. One definitional rule is worth knowing before you argue about what triggers the number: 21 NCAC 50 .0413 says a proposal or bid means a firm offer or commitment to perform work which becomes a contract on acceptance, and does not include a non-binding estimate.

North Carolina localities do not add a second plumbing license. They administer permits, and the state license is what gets you to the counter, which section 87-21(e) reinforces by requiring the license number on requests for permits issued by municipalities. In Mecklenburg County, which covers Charlotte, permitting runs through Code Enforcement. The county operates Trade Internet Permitting, described as instant online permits for trade contractors completing residential projects or commercial equipment changeouts that do not require plan review, and Homeowner Internet Permitting for residential projects where homeowners act as their own contractor. Anything needing plan review, and commercial work needing more information than the instant route allows, goes through the full application path. Two operational details matter for a plumbing contractor: permits are required to be grouped by the specific project and paid for by the general contractor or the homeowner acting as their own general contractor, and the plumbing contractor is the primary contractor for electric water heater change-outs. The Code Information and Resource Center answers on 980-314-CODE, 980-314-2633. In Raleigh, residential plumbing work is often folded into a Residential Building Alteration and Repair permit filed through the city Permit Portal, including water and sewer line replacement. Raleigh adds one requirement worth pricing in: any contractor performing construction and repair work in the public right-of-way must provide a Certificate of Eligibility and a bond of up to $5,000.00.

The board runs a public license search at public.nclicensing.org, linked from the front page of its own site as License Search, and that is the page a homeowner, a general contractor, an insurer or a permit clerk will open. Treat it as part of your marketing rather than a compliance afterthought, because three things about your business are public through it. The name is public, and it is the name listed on the license, which is why 21 NCAC 50 .0407 requires licenses to be listed in the name in which the holders conduct business and why a trade name change is a filing rather than a rebrand. The classification is public, so a customer can see whether you hold Plumbing Class I or Plumbing Class II, and a Class II licensee quoting a commercial building is visible to anyone who checks. Status is public, which matters more here than in most states because North Carolina has no renewal grace period, so a licence that lapsed on the last day of December reads as lapsed on the first working day of January while you are still quoting. The board also publishes complaint information for anyone who wants to raise an issue about licensed or unlicensed work. Put your license number on your proposals, as section 87-21(e) requires, and on your website, so the search confirms you.

These are common details other guides publish about North Carolina, but we could not verify them from the agency source. Confirm them directly before relying on them.
Yes. The North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses plumbing, HVAC, fuel gas piping and fire sprinkler contracting under Chapter 87, Article 2 of the General Statutes and the rules at 21 NCAC Chapter 50.
An individual passes the examination, and the license is then listed in the name of the business that contracts the work. Section 87-26 allows the license where one or more officers or full time employees are licensed and exercise general supervision over the work.
Section 87-21(b)(1) sets Class I as covering all plumbing, heating and fire sprinkler systems for all structures, and Class II as covering plumbing and heating systems in single-family detached residential dwellings.
Two years, stated as 4,000 hours, of on-site full time experience. Up to half of that, 2,000 hours, may be academic or technical training. A Restricted Limited Plumbing Contractor needs nine months, stated as 1,500 hours.
Rule 21 NCAC 50 .0305 sets examinations on a maximum obtainable grade of 100 points with a grade of 70 required to pass. Examinees bring their allowed reference materials to the testing center.
An application for license by examination is $150.00, made up of a $75.00 application fee and a $75.00 nonrefundable examination fee, under 21 NCAC 50 .1101(c). The annual plumbing contractor license fee is $150.00 under 21 NCAC 50 .1102.
Chapter 87, Article 2 sets no contractor surety bond and no general liability or workers compensation minimum for licensure, and the board's fee rules and application forms are silent on both. Contract and local requirements set your real limits.
On the last day of December each year. The board states there is no grace period and licensees must stop all licensed activities until renewal occurs. Late renewal adds $25.00 under section 87-22.
No. The board's education page states that mandatory continuing education was eliminated by the board in 2012 and is no longer required in order to renew licenses annually, though voluntary course work is encouraged.
Only through a reciprocal agreement, or at the board's discretion. Rule 21 NCAC 50 .0310 limits reciprocity to agreements worked out with other states, and section 87-21(g) lets the board waive the written examination on proof of substantially equivalent qualifications.
Section 87-21(e) requires the current license to be posted at the business location and its number to appear on all proposals or contracts and requests for permits issued by municipalities. The Article contains no separate advertising or vehicle lettering rule.
No, unless the owner personally installs it in non-commercial property. Rule 21 NCAC 50 .0506(b) states that the initial installation or subsequent replacement of any water heater in any structure requires a license in plumbing.
