Maryland has one of the stricter household limits in the country. Two plants per household – period – regardless of how many adults live there. If you want to make those plants count, variety selection and cultivation method both matter a lot.
Who Can Grow
Any Maryland resident who is 21 or older may grow cannabis at home for personal use. There is no registration process, no medical card required, and no permit to apply for.
If you are a registered medical cannabis patient with the Maryland Cannabis Administration, you are allowed two additional plants on top of the standard household limit – for a total of four plants per residence. That four-plant cap applies to the household, not per person, and it does not increase further regardless of how many registered patients live at the same address.
You must be growing on property you own or lease, or on property with the written consent of the person in lawful possession. Cultivation on someone else’s property without consent is a violation.
How Many Plants
Maryland law caps home cultivation at two mature cannabis plants per household. That limit does not increase if multiple adults share the same address.
Two adults living together: still two plants total. Three adults, four adults – same answer: two plants.
This is different from states like Colorado or Michigan, where the per-person limit stacks by household. In Maryland, the household ceiling is fixed.
There is no stated limit on seedlings or clones in the statute, but the practical guidance is to be conservative and stay within the spirit of the two-plant rule.
Where You Can Grow
Plants must be cultivated on property lawfully in your possession – meaning property you own, rent, or have explicit consent to use for cultivation.
The statute prohibits growing in any location where plants are visible from public areas or from a neighboring private property without the use of binoculars, aircraft, or other optical aids. That is the statutory standard verbatim.
In practice: if a neighbor could look over your fence and see a plant with the naked eye, you are out of compliance.
Indoor growing is the cleanest way to satisfy both the visibility and security requirements at once.
Security Requirements
Maryland requires that cannabis plants be kept in an enclosed, locked space that prevents access by anyone under 21. The statute uses the phrase “reasonable precautions,” and specifically identifies a locked enclosure with keys unavailable to minors as meeting that standard.
For outdoor growers, a locked greenhouse, a fenced and locked garden area, or a locked shed all work. An unfenced backyard, even one with some visual screening, does not meet the security requirement on its own.
For indoor growers, a locked grow tent or locked room in a private residence satisfies the rule.
Renters and Landlords
Maryland law allows landlords to prohibit cannabis cultivation in lease agreements. If you rent, your lease may already bar home growing – and even if it does not, your landlord can potentially restrict it.
Before starting a grow in a rental property, review your lease carefully. If the lease is silent on cannabis cultivation, that is not necessarily permission. Consider getting something in writing from your landlord before investing in equipment.
Penalties for Going Over the Limit
Violating Md. Code, Criminal Law § 5-601.2 is a misdemeanor. Penalties on conviction include up to 3 years imprisonment and/or a fine of up to $5,000.
This applies to any violation of the section – growing more than two plants, growing where plants are visible, failing to secure plants from minors, or growing on property without authorization.
The two-plant limit is firm. Growing three plants is not a gray area.
Ready to Start Growing?
Maryland’s two-plant cap puts a premium on starting with quality genetics. With only two plants, there is not much room to compensate for a weak cultivar or a bad germination. Choosing the right strains from the start matters more here than in states with higher limits.
