Adults 21 and over in Boston may grow up to six cannabis plants per person and twelve per household under MGL Chapter 94G Section 7, provided the plants are not visible from public view and are secured from minors.
MGL Chapter 94G Section 7 authorizes adults 21 and older to cultivate up to 6 mature plants for personal use, with a household cap of 12 plants regardless of how many adults live there. Boston follows the state framework and adds no additional plant cap, but enforces existing zoning and building rules: cultivation cannot occur in a public-facing window, must be in a locked space inaccessible to minors, and cannot generate odors, light, or ventilation impacts that violate Boston Code Chapter 16 nuisance standards. Tenants should also check leases, since landlords may prohibit cultivation. Selling home-grown cannabis remains illegal without a CCC license.
Exceeding plant counts, growing in public view, or selling home-grown cannabis can lead to seizure, civil fines under MGL 94G, and Boston nuisance citations for odor or building-code violations.
