Under MCL 333.27955, adults 21 and older may cultivate up to 12 marijuana plants for personal use at their primary residence, provided plants are not visible from a public place and are kept in an enclosed, locked area. Local governments cannot prohibit personal cultivation, though they may impose reasonable restrictions on commercial operations. Tenants remain subject to lease terms and federal housing rules.
Violations & Penalties
Plants exceeding 12 or visible from a public place expose the grower to civil fines and possible criminal charges under MCL 333.27965.
Frequently Asked Questions
Can my city ban home growing entirely?
No. The MRTMA preempts local prohibitions on personal cultivation by adults at their primary residence, though cities may regulate commercial cannabis activity.
Can a landlord prohibit cannabis cultivation?
Yes. The MRTMA does not override private lease agreements; landlords may prohibit cultivation, smoking, or possession on rental property through enforceable lease terms.
