Is It Legal to Grow Cannabis at Home in Maryland? (2026 Rules)

Jurisdiction: Maryland  |  Last verified: September 4, 2026  |  Adult-use rule effective: July 1, 2023

Quick answer: Yes. A Maryland adult age 21 or older may cultivate up to two cannabis plants at home, out of public view. The limit is two plants for the entire household, regardless of how many eligible adults live there. A registered Maryland medical cannabis patient may cultivate two additional plants, with no more than four plants at the residence.

Maryland home-grow rules in plain language

• Minimum age: 21 for adult-use cultivation.
• Adult-use limit: two plants per household.
• Medical allowance: a registered Maryland medical cannabis patient may cultivate two additional plants.
• Residence cap: no more than four plants at a residence when the medical allowance applies.
• Visibility: plants must be out of public view.
• Property rights: a landlord or property owner may prohibit cultivation.

Maryland’s limit is based on the household, not the number of adults. Two adults living together do not receive four adult-use plants. The ordinary household limit remains two.

How the medical allowance works

A patient who is registered with the Maryland Cannabis Administration may cultivate two plants in addition to the ordinary two-plant household allowance. The residence still cannot exceed four plants. The extra allowance is tied to current medical-program registration, not simply to having a qualifying medical condition.

Before you start

1. Count the entire household. Do not multiply the two-plant adult-use limit by the number of residents.
2. Keep plants out of public view. Choose the grow location before germinating seeds or bringing in clones.
3. Check the lease or property policy. Maryland law allows landlords and property owners to prohibit cultivation.
4. Verify medical registration. The two additional plants apply to a registered Maryland medical cannabis patient.
5. Stay within Maryland. State legalization does not change federal restrictions, including rules on federal property and interstate transport.
