Detroit Zoning Ordinance Chapter 50 lists adult-use marijuana retail, processing, grow, and consumption uses as conditional or special land uses in select B and M districts. Residential and most mixed-use districts exclude commercial cannabis activity.
Under Detroit Zoning Ordinance Article XII, marijuana retailers and microbusinesses are conditional uses in B4 (General Business) and B6 (General Services) districts and select M (industrial) districts, while growers and processors are limited to M2, M3, and M4 zones. Designated consumption establishments require additional review for ventilation and odor mitigation. The city caps the number of retailer licenses citywide and allocates them across council districts to avoid clustering. Each application goes through Buildings, Safety Engineering and Environmental Department zoning review, City Planning Commission hearing, and finally Council approval before the local license is issued. Site plans must address parking, signage, security, and odor control under city standards before occupancy.
Opening cannabis operations in a non-permitted district, exceeding the citywide retailer cap, or skipping conditional-use approval triggers zoning enforcement, license denial, and possible court-ordered closure.
