Connecticut Adult Cannabis Home Cultivation Statewide Law

Under Public Act 21-1 and Conn. Gen. Stat. Sec. 21a-279a, Connecticut adults aged 21 and over may cultivate up to three mature and three immature cannabis plants per person, capped at twelve plants per household, exclusively at their primary residence. Plants must be grown indoors, secured from minors, and not visible from public spaces. Medical patients have had similar rights since 2021. Municipalities cannot ban home cultivation outright but may regulate odor and ventilation through nuisance and building codes. Landlords may restrict cultivation in lease agreements.

Exceeding limits or cultivating outside the primary residence can be charged as illegal manufacturing or possession with intent. Penalties scale by plant count, ranging from civil fines to felony charges.
