How Michigan Plumber license verification works
A Plumber in Michigan is licensed by the MI Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: status expires issued license_type board title state related_records disciplinary_actions.
Board note: Bureau of Construction Codes licence verification — its own Accela Citizen Access site (aca-prod.accela.com/LARA), separate from the BPL MiPLUS site used by mi_lara. Plain HTTPS (rung 1): detail by number, async UpdatePanel name search per licence type. Individual types covered: Electrical Master / Journey, Plumbing Master / Journey, Residential Builder Individual / M and A Individual. Electrical / Plumbing / Mechanical Contractor and Residential Builder Company are business licences (not matched to a person); Michigan has no HVAC person licence → hvac not covered. Status 'Issued' = active; 'Hold' seen on an expired licence (left unmapped, expiry decides). 2026-11-04.
