How to Get Your Plumbing Contractor License in North Carolina

If you’re bidding or performing plumbing contracting work in North Carolina, you need a license from the NC State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors (SBPHFSC). The Board governs plumbing, heating, fuel piping, and fire sprinkler contractors across the state under G.S. Chapter 87, Article 2.

Most out-of-state contractors should expect to complete North Carolina’s licensing process from the beginning. Limited exceptions exist for certain South Carolina license holders and applicants qualifying under the Neighbor State License Recognition Act.

Can You Work Without a Plumbing Contractor License in North Carolina?

Without a license, you can’t legally perform plumbing contracting work, obtain permits, or bid on jobs in North Carolina.

G.S. 87-21 does provide narrow exemptions. Drain cleaners don’t need a license. Neither do people making minor repairs or minor replacements to already installed systems, so long as the work doesn’t require any change in energy source, fuel type, or routing or sizing of venting or piping. Licensed manufactured home set-up contractors assembling a factory designed drain line system for a manufactured home are also exempt if they obtain the required local inspection. Home inspectors, certified code-enforcement officials, and RESNET certified home energy raters are exempt to the extent they don’t claim to be or act as plumbing contractors.

Employees performing work under a licensed contractor’s supervision are generally covered by the contractor’s license and are not required to hold their own. The license responsibility sits with the contractor of record.

Unless a statutory exemption applies, you need the appropriate plumbing contractor license before you bid or perform any work.

The License Classifications

The Board issues two primary plumbing contractor license classifications under G.S. 87-21(b)(1).

A Class I license covers plumbing systems in any structure, residential or commercial. It’s the broadest license and the one most commercial contractors need. A Class II license limits you to plumbing and heating systems in single-family detached residential dwellings.

Beyond Class I and Class II, the Board issues several restricted classifications, including the Restricted Limited Plumbing Contractor license, which covers a narrower scope of work and carries lower experience requirements. There are also restricted licenses for fuel piping and work by state and local government employees.

Beyond plumbing, the Board issues separate licenses for heating, fuel piping, and fire sprinkler contractors. Those require their own examinations and are not covered here.

Which North Carolina Plumbing License Should You Get?

If you plan to work on commercial buildings, multifamily projects, or anything beyond detached single-family homes, Class I is the better long-term choice because it gives you a broader scope from the start and may save you from having to qualify for another classification later.

Class II makes sense if you’re focusing exclusively on detached residential construction and don’t plan to expand into commercial work. But if there’s any chance your scope grows, start with Class I.

Experience Requirements

Plumbing contractor applicants must have 4,000 hours (two years) of on-site, full-time experience in the installation, maintenance, service, or repair of plumbing systems, per nclicensing.org. Under G.S. 87-21(b)(3), the experience requirement may not exceed two years, and up to one-half may be in the form of academic or technical courses of study. That means a vocational or community college plumbing program can count for up to a year of your required experience.

Certified code enforcement experience and certificates in engineering or unrelated fields are explicitly excluded by the Board and don’t count toward the requirement.

For the Restricted Limited Plumbing Contractor license, the requirement drops to 1,500 hours (nine months), with up to 750 hours allowed from academic or technical training.

Current and former military personnel can use qualifying service experience. Spouses of military members may submit documentation of out-of-state licensure and sworn supervisor statements. Contact the Board at 919-875-3612 for specifics.

How Much Does a North Carolina Plumbing Contractor License Cost?

Expect to spend at least $300 in Board fees ($150 application and exam fee plus a $150 annual license fee), plus the cost of required reference books and a background check.

Here’s what to budget:

The $150 exam fee is non-refundable whether you pass or not. The annual license fee is due when you activate your license and again at each renewal. Budget for reference books separately. The Board specifies exactly which editions are accepted for the exam.

Applying for the Exam

The Board requires a completed application form with notarized signatures where indicated, a criminal background check from the Board’s approved provider, the non-refundable $150 application and exam fee, proof of experience, and the required reference books, which you’ll also need to bring to the exam.

Applications can be mailed or submitted online. The Board is currently averaging six weeks to process applications. If your application is missing anything, it goes on hold until you provide it, which adds time. Get everything right the first time.

Once approved, you’ll receive notification by email or mail with instructions for scheduling with PSI. You have 90 days from that notification date to take your exam, per G.S. 87-21(b)(6).

The Exam

Exams are administered by PSI Services LLC, computer-based and offered at testing centers in Asheville, Charlotte, Winston-Salem, Raleigh, Fayetteville, Greenville, and Wilmington.

The exam is open book. You must bring all required reference materials to the test center. They’ll be checked for compliance with the Board’s requirements before you’re allowed to sit. Check the current Book Reference List at nclicensing.org before ordering anything: the Board is specific about which editions are accepted and any required markings or modifications. Contact the Board for current time limits by classification.

You’ll know your result immediately after completing the exam. If you fail, there’s a 90-day wait before you can retest. Failing applicants can attend an exam review session in Raleigh before retesting. A Re-Examination Application and fee are required to reschedule.

Activating Your License

Passing the exam is not the finish line. Plumbing contractor applicants must submit a completed License Activation Form and the license fee to the Board within 45 days of passing. Miss the 45-day deadline and you’ll have to retake the examination.

The annual plumbing contractor license fee is $150. Once your license is issued, it expires December 31 of that year, regardless of when you received it.

Your license must be used only in the name in which it is registered with the Board.

Under G.S. 87-21(e), your license number must appear on all proposals, contracts, and requests for permits. Cinderblock stores your license number once and automatically includes it on every estimate and invoice, so you don’t have to add it manually each time.

How Long Does It Take to Get a Plumbing Contractor License in North Carolina?

Most applicants can expect the licensing process to take several weeks after submitting a complete application, plus time to schedule and pass the examination.

The Board does not publish a guaranteed end-to-end timeline. Allow extra time on all ends, and make sure your application is complete before you submit it.

Renewing Your License

All NC plumbing contractor licenses expire on December 31, regardless of when they were issued. Renewal opens October 1, ninety days before expiration. Don’t wait for a renewal invoice. If the Board has your email, you’ll get a notice, but you’re responsible for renewing whether you receive one or not.

A late fee of $25 applies to renewals received after January 31. Let your license expire without renewing and you must stop performing, bidding, and offering plumbing contracting work until the license is reinstated. An expired license can be reinstated within three years of expiration by paying all back fees and late fees. After three years, reinstatement requires retaking and passing the exam.

One notable difference from NC electrical contractor licensing: there is no continuing education requirement for renewal. The Board eliminated mandatory CE on December 31, 2012. Voluntary continuing education is still encouraged.

Reciprocity and Out-of-State Licensees

North Carolina has no formal reciprocity agreements with any other state. Most out-of-state contractors should expect to complete the full licensing process.

Two partial pathways exist. First, the Technical Examination Waiver Agreement with South Carolina allows SC-licensed plumbing and HVAC contractors to waive the technical portion of the NC exam, but they must still pass the NC business law exam.

Second, the Neighbor State License Recognition Act allows current NC permanent residents who hold active licenses in Georgia, South Carolina, Tennessee, Virginia, or West Virginia to apply for equivalent NC licensure. Details and eligibility requirements are on the Board’s applicant information page.

The Board also has discretion under G.S. 87-21(g) to grant a license without written examination to out-of-state licensees whose qualifications are substantially equivalent to NC holders of the same class. This is not automatic. Contact the Board directly at 919-875-3612 to confirm whether it applies to your situation.
