Cass County, MO Cannabis Regulations: Dispensary Zoning (2026)

261 of the Cass County Code applies to every medical marijuana facility, comprehensive marijuana facility and microbusiness in the unincorporated county, a list that by its own terms covers cultivation facilities, dispensary facilities, infused-products manufacturing facilities, testing facilities, transportation facilities and wholesale facilities. The ordinance treats the building itself as the zoning control: a facility cannot be located in a building that contains a residence, and unless the operator is separately licensed as an outdoor medical marijuana cultivation facility or a comprehensive marijuana cultivation facility, every operation and every bit of stored product, material or equipment has to stay inside a fully enclosed building.

No marijuana may be smoked, ingested or otherwise consumed on the premises of any medical facility or marijuana facility, and a ventilation system must be installed and operated so that no odor of marijuana leaves the premises or is detectable by a person with a normal sense of smell outside the parcel boundary. m. on Sunday. The Cass County Planning and Zoning Department administers the zoning and building-permit review for these facilities in the unincorporated area, and a separate school, day care and church buffer in the same section applies on top of these building and hours standards.
