Moving to North Carolina as a master plumber: every state's rule

North Carolina has no license titled master plumber. Its highest plumbing credential is the person-held Plumbing Contractor license issued by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G.S. The individual who passes the two-part examination (technical plus business and law) is the licensee, may list the license in a firm name, and pays an annual license fee after activation. A first-time applicant needs 4,000 hours of on-site plumbing experience (up to half academic or technical training), and out-of-state hours are accepted. The Board states it has no license reciprocity with any state; the only technical-exam waiver is with South Carolina (NC business-law exam still required). North Carolina residents licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia may seek licensure without examination under the Neighbor State License Recognition Act (G.S. 93B-15.3). Restricted Limited Plumbing Contractor (1,500 hours, 2-inch and smaller exterior water/sewer/irrigation backflow) is a narrower contracting class, not a master equivalent.
