Plumber License from New Hampshire to North Carolina: Does It Transfer? (2026)
Does North Carolina accept a New Hampshire plumbing license?
A plumbing license transfers from New Hampshire to North Carolina by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors, verify your New Hampshire license, and meet North Carolina's endorsement requirements. North Carolina has no license reciprocity; every applicant must meet the NC experience requirement and pass the NC business/law exam section. Under a Technical Examination Waiver Agreement it waives ONLY the technical exam section for South Carolina plumbing contractors who passed the SC technical exam (SC Residential Plumbing maps to NC Plumbing Class II; SC Commercial Mechanical Plumbing (PB) maps to NC Plumbing Class I). Separately, under G.S. 87-21(g) the Board may, at its discretion, license an out-of-state contractor of the same or equivalent class without written examination if its standards are found substantially equivalent.

Verdict
Licensure by endorsement
New Hampshire is not among the states North Carolina names for an exam waiver, so this move runs on the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors's individual endorsement or equivalency review rather than a guarantee. Bring your New Hampshire license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
What's different between New Hampshire and North Carolina
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into North Carolina. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
New Hampshire to North Carolina (this page): Licensure by endorsement.
North Carolina to New Hampshire (the reverse move): Licensure by endorsement.
The route is the same in both directions.
- Does coming from New Hampshire matter?
New Hampshire gets North Carolina's most common result: 41 of 50 origins (the other 49 states and DC) get the same one, so for most movers the origin does not change the answer.
The others get: no state license to transfer (9).
- Application fee
North Carolina lists $30–$150 for an out-of-state applicant and New Hampshire lists $190–$210 for the reverse move; neither may be the full cost.
- Processing time
North Carolina lists 4–6 weeks; New Hampshire has no verified processing-time figure on file, so the two cannot be compared here.
- Exam rules on record
North Carolina and New Hampshire carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- North Carolina (this move): North Carolina has no license reciprocity; every applicant must meet the NC experience requirement and pass the NC business/law exam section. Under a Technical Examination Waiver Agreement it waives ONLY the technical exam section for South Carolina plumbing contractors who passed the SC technical exam (SC Residential Plumbing maps to NC Plumbing Class II; SC Commercial Mechanical Plumbing (PB) maps to NC Plumbing Class I). Separately, under G.S. 87-21(g) the Board may, at its discretion, license an out-of-state contractor of the same or equivalent class without written examination if its standards are found substantially equivalent.
- New Hampshire (the reverse move): New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination
What changes, New Hampshire → North Carolina
| New Hampshire (current) | North Carolina (destination) | |
|---|---|---|
| Application fee | $190–$210 (Journeyman Plumber application fee $190 plus $20 certificate fee; the fingerprint / criminal background check fee is additional and paid separately. (Master Plumber application fee is $310)) | $30–$150 ($100 per examination section; $30 application fee and $150 annual license fee (Board fee schedule per its relocation/military provisions); South Carolina Technical Examination Waiver applicants still pay for and pass the NC business exam; CastleBranch background report is at the applicant's expense) |
| Processing time | No board-stated processing time; under Plc 313.07(c) OPLC may issue an 'Active-Provisional' license once the application, fee, and fingerprints are submitted and the applicant qualifies by endorsement, pending background-check results | 4–6 weeks (Board-stated application-processing time; add time to schedule and pass the exam(s) with PSI) |
| Licensing authority | New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board | North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors |
The destination column is what you must satisfy — North Carolina sets the rules for this move.

Frequently asked questions
Can I keep my New Hampshire plumbing license after I'm licensed in North Carolina?
Yes — plumbing licenses in different jurisdictions run independently. Keep the New Hampshire credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
