Moving to Michigan as a master electrician: every state's rule

Michigan issues a statewide, person-held Master Electrician license through LARA's Bureau of Construction Codes under MCL 339.5713; the Electrical Contractor license is a separate business credential that requires a qualifying master and no exam, and is not covered here. A new master applicant must be at least 22, have held an electrical journeyman license for at least two years, document 12,000 hours over at least six years under a master electrician with notarized employer letters, pass the PSI-administered master exam (75% to pass, 2023 NEC) for a $100 exam fee, and pay the $50 license fee; the license renews every year for $50. Michigan has no reciprocity agreements with any state and requires every out-of-state master to pass the Michigan exam, though out-of-state experience may be credited after board review. Under MCL 339.5733 the City of Detroit licenses master electricians who are Detroit residents, and Detroit licenses are valid statewide.
