New York's MRTA allows Brooklyn adults 21+ to grow up to 6 cannabis plants (3 mature, 3 immature) per person, max 12 per household, for personal use.
Under New York's Marihuana Regulation and Taxation Act (MRTA), signed March 31, 2021, adults 21 and older may legally cultivate cannabis at home in Brooklyn — however, the home cultivation provision only took effect after the first adult-use retail dispensary opened (December 2022). Each adult may grow up to 3 mature and 3 immature plants. A household (regardless of occupants) may not exceed 12 plants total (6 mature, 6 immature). Plants must be grown out of public view and secured against access by anyone under 21. Landlords in Brooklyn can prohibit cultivation in rental units. Co-op and condo boards commonly restrict indoor grows in house rules. The NY Office of Cannabis Management (OCM) enforces. Outdoor cultivation visible from the street is prohibited.
