Moving to North Carolina as a journeyman plumber: every state's rule
North Carolina does not issue a statewide journeyman plumber license, so there is no reciprocity to speak of. Here is what that means in practice.
North Carolina journeyman plumber · “Journeyman plumber (city or county card, where issued)”
Licensed by cities and counties
Issued by North Carolina cities and counties (no statewide journeyman plumber license)
North Carolina does not issue a statewide journeyman plumber license. The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses plumbing contractors (Class I for all structures and Class II for single-family detached dwellings) and optional Plumbing Technician classifications for employees of contractors or of state, local-government or private-educational employers; G.S. 87-21 never uses the word journeyman. A W-2 employee may perform plumbing work under a licensed plumbing contractor without holding a technician license, so the technician credential is not a true journeyman card and is not mapped here. Some cities and counties may still issue local journeyman or tradesman cards for work inside their inspection jurisdictions. An inbound journeyman should ask the local inspections department where the job is located; there is no state endorsement, reciprocity list or default path at this level.
How local licensing works in North Carolina
The municipalities listed are large inspection jurisdictions that historically have run local trades programs; confirm each city's current plumber/journeyman page before relying on a local card. Restricted Limited Plumbing Contractor (1,500 hours) and Plumbing Technician (2,500–3,000 hours) are state credentials of the contractor board, not municipal journeyman licenses.
