Massachusetts Cannabis Dispensary Local Zoning Control

Under M.G.L. c.94G Section 3(a), a Massachusetts city or town adopts ordinances and by-laws imposing reasonable safeguards on marijuana establishments so long as they are not unreasonably impracticable and do not conflict with the statute or the Cannabis Control Commission's regulations. Localities govern time, place and manner and may limit the number of establishments, but they cannot cap retailers below 20 percent of the community's off-premises alcohol licenses without approving the by-law at the ballot box. Zoning cannot block converting an existing medical marijuana treatment center to adult-use. Every licensed operator also negotiates a host community agreement, whose impact fee ends after the eighth year of operation.

A zoning ordinance that conflicts with the statute or caps retailers below the 20% floor without voter approval is unenforceable; operators without a host community agreement cannot be licensed by the Cannabis Control Commission.
