Plumber License from Minnesota to North Carolina: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors ↗
A plumbing license transfers from Minnesota 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 Minnesota 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..
