Can I ban marijuana in a state where it is legal?

For private landlords, yes in nearly every legal state. Recreational legalization does not override a landlord's right to set conditions on use of the property. The most defensible bans target smoking (which raises insurance and second-hand smoke concerns) and on-site cultivation (which raises moisture, electrical, and lease-purpose concerns).

What about medical marijuana patients?

Most states do not require private landlords to accommodate medical marijuana use the way they would accommodate other disability-related medications. The ADA explicitly excludes marijuana use even when state law allows it, because marijuana remains federally illegal. A handful of states (New York, New Jersey, Connecticut) have stronger tenant protections but most leases can still restrict smoking and cultivation.

Are edibles treated differently than smoking?

Yes, and most landlord interests do not extend to edibles. Edibles produce no smoke, no odor, no fire risk, and no second-hand exposure. A blanket "no marijuana use" clause that bans edibles is harder to enforce and may not be worth fighting over. The cleaner approach is to ban specific harms: no smoking of any substance, no cultivation, no commercial activity.

What about Section 8 or other federally subsidized housing?

Federal HUD rules require public and federally subsidized housing to prohibit marijuana use entirely, including in legal-state recreational and medical contexts. Landlords participating in HUD programs must enforce these prohibitions to remain eligible. This applies even in fully legal states like California, Colorado, and Washington.

Can I evict a tenant for marijuana use?

If the lease contains an enforceable prohibition and the use is documented (complaints, odor, smoke, cultivation evidence), yes, through the normal eviction process. For HUD-subsidized housing, eviction is often required by federal rule. For private rentals in legal states, the tenant's lease violation is the basis, not the marijuana use itself. You still need a proper notice and proper court process.

What about CBD or hemp products?

CBD products with less than 0.3 percent THC are federally legal under the 2018 Farm Bill and generally cannot be prohibited the same way as marijuana. Most landlord concerns (smoke, odor, fire) do not apply to typical CBD use (oils, edibles, topicals). A reasonable clause distinguishes between federally legal CBD and federally illegal marijuana to avoid overreach.

Marijuana Clauses in Residential Leases: What Is Enforceable in 2026

Recreational legalization in 24 states (and growing) has not removed a landlord's right to ban marijuana use on the premises. But blanket "no marijuana" clauses overreach and create enforcement problems. The defensible approach: ban specific harms (smoke, cultivation, commercial activity) rather than the substance itself.

Key Points

Private landlords can prohibit marijuana smoking and cultivation even in states where recreational use is legal, because state legalization does not override lease terms.
Banning specific harms (smoke, cultivation, commercial activity) is more defensible than a blanket "no marijuana use" clause that courts may view as overreaching.
Most states do not require landlords to accommodate medical marijuana cardholders, though New York, New Jersey, and Connecticut offer some tenant protections.
Federally subsidized housing must prohibit marijuana use entirely under HUD rules, with no exception for state legalization or medical cardholders.
Edibles present no smoke, odor, or fire risk, so a clause targeting those specific harms will not reach private edible use that landlords cannot reasonably detect.

Why landlords can ban marijuana in legal states

Recreational legalization regulates the relationship between the state and the user. It does not regulate the relationship between a landlord and a tenant. Federal law still classifies marijuana as a Schedule I controlled substance, which means landlords are generally free to set lease terms restricting its use without running into anti-discrimination or accommodation requirements.

The exceptions are narrow: a handful of states have specific tenant protections for medical marijuana cardholders, and some local ordinances (rare) restrict landlord authority. Federally subsidized housing goes the other direction: HUD requires bans.

The four risks landlords actually care about

Second-hand smoke. Travels through HVAC, hallways, and shared walls. Generates complaints from neighbors. Implicates implied warranty of quiet enjoyment for other tenants.
Cultivation damage. Indoor growing operations produce humidity, mold, electrical overload, and odor. Many insurance policies specifically exclude grow-related damage.
Insurance and lender restrictions. Many landlord insurance policies and commercial mortgages prohibit on-site marijuana activity. A lease that allows it may void coverage.
Federal law for subsidized properties. HUD-subsidized housing must prohibit use entirely or risk losing federal funding.

A defensible clause structure

Instead of "no marijuana use," consider banning specific behaviors:

No smoking or vaporizing of any substance (tobacco, marijuana, or other) inside the premises or within 25 feet of any door or window
No cultivation, growing, or processing of marijuana or marijuana plants on the premises
No manufacturing, packaging, or commercial activity involving marijuana or any controlled substance
Compliance with all federal, state, and local laws regarding controlled substances

This structure addresses the actual harms, survives challenges in legal states, and does not overreach into private edible use that landlords cannot reasonably regulate or detect.

Medical marijuana exceptions

Most states do not require landlords to accommodate medical marijuana the way they would accommodate other prescriptions. The ADA explicitly excludes marijuana use. State fair housing laws vary, but only a few states (New York, New Jersey, Connecticut, and a small number of others) provide express protection for medical cardholders.

Even in states with cardholder protection, the protection usually covers possession and use, not smoking or cultivation. A landlord can still prohibit smoke and grow operations while allowing edibles or other non-disruptive consumption.

Federally subsidized housing: ban required

If the property is Section 8, public housing, project-based rental assistance, or other HUD program, federal rules require:

A lease prohibition on marijuana use
Eviction (not just lease violation) for documented use
No medical exception, even for state-licensed cardholders
Compliance even in fully legal states

Failure to enforce can jeopardize the property's federal funding eligibility.

Enforcement: documentation matters

Lease violations need evidence. For marijuana clauses, useful documentation includes:

Written complaints from neighbors with date and time
Inspection notes referencing odor or visible smoke
Photographs of cultivation setups (lights, soil, plants, equipment)
Maintenance records showing damage attributable to cultivation (electrical, moisture, mold)

A notice to cure or quit gives the tenant the chance to fix the violation. If the violation is not cured within the notice period, proceed with eviction through normal court process. See our eviction notice mistakes guide for proper service.

What not to put in the lease

"Tenant agrees not to use marijuana under any circumstances" (overreach, hard to enforce on private edible use)
"Landlord may inspect for marijuana use at any time" (violates entry notice rules)
"Tenant waives all rights under state medical marijuana laws" (cannot waive statutory rights)
"Possession of marijuana on premises is grounds for immediate eviction without notice" (still requires statutory notice and court process)
