Do you need a mold inspector license in Minnesota?
Minnesota does not license or register mold inspectors. The state spans cold to very-cold zones (IECC 6A around the Twin Cities, 7 in the north), where a strong outward winter vapor drive, interstitial condensation, ice damming, and tight-envelope ventilation issues dominate the moisture picture. The Minnesota Department of Health publishes mold guidance but issues no mold credential. Minnesota inspectors typically hold a voluntary IICRC or ACAC certification.
Is a license required?
Minnesota does not license mold inspectors or assessors at the state level. Inspectors typically hold a voluntary certification (such as IICRC or ACAC) rather than a state license.

Common questions
Do you need a license to be a mold inspector in Minnesota?
No. Minnesota issues no state mold-inspector license, so there is no state exam or registration to complete. Inspectors instead show competence through voluntary certification such as IICRC or ACAC and by following recognized industry standards.
Who regulates mold inspection in Minnesota?
No single board regulates mold inspection in Minnesota. The state's environmental and health agencies publish general mold guidance instead: https://www.health.state.mn.us/.
