Michigan law allows adults 21 and over to grow up to 12 cannabis plants at home, and Dearborn enforces general nuisance rules but cannot ban personal cultivation.
Under the Michigan Regulation and Taxation of Marihuana Act, approved by voters in 2018, adults 21 and over may cultivate up to 12 marihuana plants at their private residence for personal use, provided the plants are not visible from a public place and are grown in an enclosed, locked area. Dearborn cannot prohibit this activity, but may enforce general nuisance, odor, electrical, and building code provisions against grows that create neighborhood impacts. Landlords may still prohibit marihuana cultivation and smoking in lease agreements, and federally subsidized housing remains off-limits. Selling or gifting large quantities from a home grow is prohibited, and plants above the 12-plant limit are subject to state criminal penalties.
