NYC Home Cannabis Cultivation

Last verified: April 2026

The Plant-Count Rule

Under the MRTA and the CCB’s adult-use home-grow regulations finalized in 2024 (9 NYCRR Part 113), an adult 21 or older in NYC may cultivate:

• 3 mature plants — flowering, harvest-stage
• 3 immature plants — vegetative or seedling stage

Per residence — not per person — the household cap is 6 mature plus 6 immature plants. So a household with two adults can grow 6 + 6, but a household with four adults is capped at 6 + 6, not 12 + 12. The household cap was a deliberate choice to prevent personal-cultivation loopholes from becoming gray-market production sites.

The “Secured” Requirement

Plants must be grown in a secured enclosed area not visible from a public place “without the use of binoculars, aircraft, or other optical aids.” In NYC’s dense vertical environment, that means:

• Inside the residence (closet, spare room, basement, attic) — the most common option;
• On a private rooftop or terrace with adequate screening to prevent visibility from neighboring buildings, the street, or aircraft — technically permitted but practically difficult in most NYC settings;
• Inside a private outdoor enclosure (e.g., a backyard greenhouse) with similar screening — rarely available outside Staten Island and parts of Queens.

Lease, Co-op, and Condo Restrictions

The MRTA does not override private lease or co-op/condo board rules. A landlord, co-op board, or condo board may prohibit cannabis cultivation as a condition of tenancy or ownership. Many NYC apartment leases include clauses that effectively forbid cultivation due to ventilation, fire-safety, electrical-load, or odor concerns. Tenants should review lease terms before starting a home grow; eviction for unauthorized cultivation is legally possible even where state law permits the cultivation itself.

Practical Considerations for NYC Apartments

• Electrical load. A small home-grow with LED lighting and ventilation can add 200–800 watts of continuous load. Older NYC building wiring may not handle that addition; consult an electrician.
• Ventilation and odor. Carbon-filter ventilation systems are nearly mandatory in apartment grows. Cannabis odor in a multi-unit building can prompt complaints, neighbor reports to NYPD or to building management, and (in NYCHA) lease-termination proceedings.
• Humidity and mold. Indoor cultivation creates humidity that can contribute to mold problems — an issue with substantial liability exposure in NYC’s old housing stock.
• Pest management. Spider mites, aphids, and other indoor cultivation pests can spread to neighboring units.

NYCHA and Federally Subsidized Housing

Cannabis cultivation in NYCHA public housing remains prohibited under federal Department of Housing and Urban Development (HUD) rules, which categorize cannabis as illegal regardless of state law. The same applies to HUD-funded Section 8 tenancies and HUD-financed cooperatives and condominiums. NYCHA tenants can lose tenancy for cultivation. The Public Housing & Cannabis Project at the Drug Policy Alliance has documented these federal-versus-state conflicts in detail.

Selling Home-Grown Cannabis — Don’t

Home-grown cannabis may be consumed personally, gifted up to 3 oz / 24 g to other adults 21+ without compensation, or otherwise stored at home (within the 5 lb cap). It may not be sold, exchanged for compensation, or transferred to the licensed market. The licensed cultivator queue is separate; home growers cannot become legal cannabis sellers without going through OCM’s licensing process.

Equipment Sourcing

Hydroponics and grow-equipment retailers operate openly in NYC. Equipment purchases are not themselves regulated. Seed and clone sources are more constrained: licensed nursery and microbusiness retailers may sell clones; the gray-market clone market that flourished pre-MRTA still exists but operates at the operator’s legal risk.
