Who Can Grow
Any adult 21 or older who resides in the District of Columbia may grow cannabis at home under Initiative 71. No license, registration, or permit is required. There is no application process and no fee.
DC voters passed Initiative 71 in November 2014 by a 64.87% margin. It took effect on February 26, 2015, making DC one of the earliest jurisdictions in the country to legalize both home cultivation and personal possession.
How Many Plants
Each adult 21 or older may cultivate up to six cannabis plants, with no more than three being mature and flowering at any one time. The limit applies per adult, not per household.
That means if two adults 21 or older live in the same home, the household can legally maintain up to 12 total plants with no more than six in flower at once. The per-person structure is more generous than most states that cap cultivation at the household level regardless of how many adults reside there.
The three-plant flowering limit is designed to allow a continuous harvest cycle. You can run three plants in vegetative growth alongside three in flower simultaneously, maintaining a staggered rotation for more consistent personal supply.
Where You Can Grow
Plants must be grown out of public view. Initiative 71 does not specify “enclosed and locked” in the same explicit terms used by many state statutes, but the requirement that plants not be visible from public space is clear.
For indoor growers, a standard grow tent or dedicated room satisfies the intent of the law. For outdoor growers, plants should not be visible from the street, sidewalk, or any public area. A private, fenced backyard where plants cannot be seen from public vantage points is the practical standard.
Cultivation must take place at your own residence. Growing at another person’s property, even with their permission, is not covered under the personal cultivation right.
The Unusual Sales Situation
DC’s cannabis laws are unlike any state in the country. Home growing and personal possession are fully legal under Initiative 71. But adult-use retail sales remain blocked by Congress.
Here is why: The District of Columbia is not a state. Congress has oversight authority over DC’s budget and laws through a provision called the “Harris rider,” which has been attached to federal spending bills year after year since 2014. This rider prohibits DC from using local funds to enact laws or regulations that would reduce penalties for Schedule I substances, effectively blocking DC from building a regulated commercial cannabis market the way states can.
The result is a legal environment where:
- You can legally possess up to 2 ounces of cannabis
- You can legally grow your own at home
- You can legally transfer up to 1 ounce to another adult 21+ at no charge
- But you cannot legally walk into a store and buy recreational cannabis
The only retail option is the DC medical cannabis program, which allows adults 21 and older to self-certify as patients and purchase from licensed dispensaries without a doctor’s recommendation. In practice, this functions as a quasi-retail market for residents willing to register.
As of early 2026, no standalone adult-use retail framework has cleared federal restrictions, though DC advocacy groups and the DC Council continue to push for change.
What You Can Do With Your Harvest
Under Initiative 71, an adult 21 or older may transfer up to 1 ounce of cannabis to another adult 21 or older at no charge. No money, goods, or services can be exchanged.
The “gifting” model that operated for years in DC, where cannabis was included as a free item alongside a paid purchase of something else, has been shut down through enforcement action. That commercial gifting loophole is closed. Transferring your own homegrown cannabis to a friend at no charge remains legal. Running a business that bundles cannabis with other purchases does not.
You cannot sell homegrown cannabis without a commercial license. You cannot transport cannabis across state lines. That is a federal crime regardless of what either jurisdiction allows.
Federal Property: A Hard Line
This matters more in DC than anywhere else. The District contains an enormous amount of federally owned land: national parks, the National Mall, federal buildings, military installations, Smithsonian properties, and more.
Possessing or consuming cannabis on any federally owned property is illegal under federal law, regardless of what DC law permits. Initiative 71 provides no protection on federal land. This includes:
- National Park Service property (Rock Creek Park, the National Mall, etc.)
- All federal buildings and grounds
- Metro stations and federal transit facilities
- Airports (Reagan National, Dulles, BWI)
- Any property controlled by a federal agency
The Metropolitan Police Department generally enforces DC law in the District’s residential and commercial areas. Federal law enforcement operates independently on federal land, and the current administration has signaled a more aggressive posture toward cannabis in DC. Stay off federal property with cannabis.
Penalties for Violations
Violations outside Initiative 71’s protections include:
- Public consumption: Illegal. Fine up to $500 for smoking or consuming in public spaces, parks, streets, bars, restaurants, or anywhere the public is invited.
- Possession over 2 oz: Criminal offense.
- Sale without a license: Criminal offense. Selling any amount outside the licensed medical system is illegal.
- Under-21 possession: Prohibited. Persons under 21 may not possess cannabis under any circumstances.
- Cultivation beyond limits: Growing more than 6 plants per adult (or more than 3 mature) violates Initiative 71 and falls under DC’s controlled substances laws.
Federal penalties can apply independently on federal property and are not limited by DC law.
Outdoor Growing in DC
DC sits in USDA hardiness zones 7a to 7b. The outdoor season typically runs from late April through mid-October, with last frost around late March and first fall frost in late October or November. Most of the District has roughly 200 frost-free days, one of the longer windows on the East Coast.
Photoperiod strains that need a full season to finish can work well outdoors in DC. A plant started in late April or May will begin its natural flower cycle as days shorten in late August and typically be ready for harvest in October.
Autoflowering varieties are well-suited to DC’s climate and give growers flexibility in tight urban spaces. A fast autoflower completing in 70-80 days can run outdoors from late May to late August, leaving time for a second run before the season ends.
The public visibility requirement is the main practical constraint for outdoor growers in DC. Row houses, apartments, and dense urban lots don’t always offer easy screening. A private rooftop or well-fenced backyard that cannot be seen from the street or neighboring properties is the cleanest outdoor setup.

Frequently Asked Questions
Is home growing legal in Washington DC?
Yes. Adults 21 and older have been able to grow cannabis at home in DC since February 26, 2015, under Initiative 71. No permit or registration is required.
How many plants can I grow at home in DC?
Up to six plants per adult, with no more than three mature and flowering at one time. If two adults 21 or older share a residence, the household limit is 12 total plants with six in flower.
Do I need a license or permit to grow cannabis at home in DC?
No. Home cultivation within the legal limits under Initiative 71 requires no license, permit, or registration.
Can I grow outdoors in DC?
Yes, but plants must not be visible from public view. An open front yard or a balcony visible from the street does not satisfy that requirement. A private, enclosed backyard or screened rooftop is the appropriate outdoor setup.
Why can’t I buy recreational cannabis at a store in DC?
Congress has attached a budget rider, sometimes called the “Harris rider,” to federal spending bills that prevents DC from using local funds to legalize and regulate commercial adult-use cannabis sales. DC is a federal district, not a state, so Congress retains this oversight authority. Retail sales remain blocked despite voter legalization in 2014.
Can I give my homegrown cannabis to a friend?
You may transfer up to 1 ounce to another adult 21 or older at no cost. No money, goods, or services can change hands. Commercial gifting arrangements where cannabis was bundled with paid purchases have been shut down and are no longer a legal gray area.
Can I consume cannabis on the National Mall or in federal parks?
No. Federal property is federal jurisdiction. Possessing or consuming cannabis on any federally owned land in DC is illegal under federal law, and Initiative 71 does not apply there.
Can I order cannabis seeds in DC?
Yes. Hemp seeds with less than 0.3% delta-9 THC are federally legal under the 2018 Farm Bill and legal to order and possess in DC. Triangle Hemp ships feminized cannabis seeds to Washington DC. Shop our seed catalog here.
