Adults 21 and over in Newton may grow up to 6 cannabis plants per person (max 12 per household) under MGL c.94G. Plants must be out of public view and secured from minors.
Under Massachusetts Cannabis Control Act (MGL c.94G s.7), adults 21 and over may cultivate up to 6 cannabis plants for personal use at their primary residence, with a maximum of 12 plants per household regardless of how many adults live there. Newton follows state law without additional local cultivation restrictions. Plants must not be visible from a public place without a binocular, aircraft, or other optical aid - meaning they should be inside, in a greenhouse, or behind a fence or screening. Cultivation must occur at the person's primary residence, not at second homes or rentals without the landlord's permission. Landlords may prohibit cultivation in lease terms. Plants must be secured from access by persons under 21, such as in a locked room or enclosure. Harvested cannabis in excess of 1 ounce at home must be kept in a locked container. Selling home-grown cannabis is illegal without a state retail license. Hydroponic and indoor setups must comply with electrical and building codes - contact Inspectional Services for large-scale setups.
