Eligibility Requirements

Applicants must be at least 18 years old. Applicants must provide a Social Security Number. The Board does not list North Carolina residency as an examination prerequisite; qualifying experience from other states may be submitted.

Good moral character

The examination application requires disclosure of criminal history and supporting records as directed by the Board.

Background investigation

Obtain criminal-record information from the Board-approved provider and submit the documentation required in the current application packet.

Experience and Education

Eligibility requires 2 years (4,000 hours) of on-site, full-time experience installing, maintaining, servicing, or repairing plumbing systems related to the class sought. The same 4,000-hour requirement applies to P-I and P-II contractor examinations., documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

• Board current/past licensed-employer statement or employment-history form, completed and notarized where required
• W-2s and/or 1099s supporting the verified experience
• Tax returns for relevant years when documenting self-employment

Education substitution

Up to 2,000 hours (45 quarter hours or 30 semester hours) may be academic or technical training directly related to the requested classification.

Exam Requirements

Testing provider or authority: North Carolina Board examinations are computer-based and administered by PSI Services LLC after Board approval.. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

• Technical examination for the selected plumbing class (Board-published duration) — question count: confirm with the authority, 240 minutes, passing score: confirm in the current candidate bulletin
• North Carolina Business and Law examination (unless the Board’s current exemption applies) — question count: confirm with the authority, 90 minutes, passing score: confirm in the current candidate bulletin

Examination fee: $150 nonrefundable application-and-examination fee per examination ($75 application + $75 examination), effective June 1, 2026.

Retake policy: The authorization period is 90 days. After a failed examination, wait 90 days, then submit a re-examination application and fee. A passing applicant must submit the activation form and license fee within 45 days or retest.

Insurance and Bonds

This credential carries no state-level surety bond requirement under the cited sources. Individual jobs may still trigger a permit or public-works bond, which should be verified before bidding.

General liability

The Board’s contractor examination and activation materials do not state a Board-level general-liability minimum. Project owners or local requirements may still require coverage.

Workers' compensation

Workers’ compensation obligations are governed separately by the North Carolina Workers’ Compensation Act; confirm coverage duties with the Industrial Commission for the business’s workforce.

Renewal and Continuing Education

Renewal of the North Carolina Plumbing Contractor (P-I or P-II) comes due every year. As cited, the renewal fee stands at $150. Licenses expire December 31 each year. Renewal opens about October 1. An expired license may be renewed for up to three years with back and late fees; thereafter, re-examination is required.

Continuing education: No routine continuing education is required for renewal. The Board encourages voluntary education and can require disciplinary education in a case.

Reciprocity

The NASCLA Accredited Examination is not accepted by North Carolina for this classification.

The Board states that it has no license-reciprocity agreements. Do not treat the limited South Carolina technical-exam waiver as full reciprocity.

Plumber Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare North Carolina's requirements against the bordering jurisdictions before committing to an application:

• Georgia Plumber License Requirements — Georgia Master Plumber (Class I or Class II)
• South Carolina Plumber License Requirements — South Carolina Commercial Plumbing Contractor License — Mechanical Classification
• Tennessee Plumber License Requirements — Tennessee CMC-A Plumbing Contractor (LLP Limited Licensed Plumber for projects under $25,000)
• Virginia Plumber License Requirements — Virginia Master Plumber Tradesman License

Step-by-Step Application Roadmap

1. Choose the plumbing classification. Select P-I for work in any building or P-II for single-family detached dwellings only; confirm any restricted-classification scope with the Board.
2. Document 4,000 qualifying hours. Use the Board’s experience forms and supporting employment records. Relevant academic or technical training can count for up to 2,000 hours.
3. Apply to the Board. Submit the current examination packet, criminal-record documentation, experience evidence, and the $150 application-and-examination fee.
4. Schedule and pass the PSI examinations. After approval, schedule within the 90-day authorization period. Contractor applicants ordinarily take both the technical and Business and Law parts.
5. Activate the license promptly. File the activation form and $150 license fee within 45 days of passing. Renew annually to keep the credential active.

Common Filing Mistakes

Working from the cited board instructions, here are the snags most likely to trip up a North Carolina Plumber filing.

Using the wrong scope

P-II is limited to single-family detached dwellings; P-I is the class for plumbing systems in any building.

Assuming full reciprocity

The current South Carolina arrangement is a limited technical-exam waiver, not a reciprocal North Carolina license.

Relying on the old $100 exam fee

The Board announced an increase to a $150 application-and-examination fee effective June 1, 2026.

Missing the activation deadline

After passing, submit the activation form and fee within 45 days or the Board requires a retest.

Missing annual renewal

Every license expires December 31; there is no routine CE requirement, but the fee and renewal still must be completed.
