Michigan licensing & zoning
What is the difference between opting in and opting out in Michigan?

The answer
Under medical law (MMFLA), a municipality must affirmatively opt in by ordinance before any medical facility can operate — silence means prohibition. Under adult-use law (MRTMA), establishments are permitted by default unless the municipality passes a prohibition ordinance and opts out — silence means permission, subject to zoning and the state buffer rule.
Why the direction is reversed
The two statutes were adopted four years apart by different mechanisms — MMFLA by the legislature in 2016, MRTMA by citizen initiative in 2018 — and each set its own default. That reversal is the single most misunderstood point in Michigan siting: a broker or operator who assumes both programs work the same way will misdiagnose a municipality's actual posture.
Diligence differs accordingly
For a medical deal, confirm the authorizing ordinance exists, which facility types it names, and any numeric cap. For an adult-use deal, confirm no prohibition ordinance exists, then move straight to zoning: permitted districts, caps, competitive scoring, and conditional-use requirements, since the establishment is presumptively allowed absent that prohibition.
Comparison
MMFLA (medical) vs MRTMA (adult-use) default posture
| Program | Statute | Default posture | Silence means |
|---|---|---|---|
| Medical | MMFLA (2016) | Opt IN required | Prohibited |
| Adult-use | MRTMA (2018) | Opt OUT required to prohibit | Permitted |
