Full Breakdown

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.
