Opt-Out
Last updated
Also called: opted out · prohibition ordinance · adult-use opt-out · mrtma opt-out
MRTMA's default is permission, not prohibition. Adult-use cannabis establishments are allowed in a Michigan municipality unless that municipality affirmatively adopts an ordinance completely prohibiting them, or limiting their number. A municipality that has taken no action has not closed itself to adult-use licensing — silence means permitted. Affirmative opt-in is the MMFLA (medical) rule, and conflating the two is the single most common error in Michigan cannabis siting.
In practice a large share of Michigan municipalities have adopted prohibition ordinances, which is why site selection still starts by filtering the map to jurisdictions that permit the specific license type, before any property-level analysis. What matters is the text of the local ordinance, not an assumption about the statewide default in either direction.
Opt-out status is not permanent: municipalities revisit the question, sometimes via citizen-initiated ballot measures under MRTMA's petition provisions, which is worth tracking for buyers taking a longer-term view of an otherwise closed submarket.
