Cannabis & Marijuana Rental Rules in Michigan 2026

Landlord ban authority, possession and home-grow limits, medical patient housing rules, and federal Section 8 restrictions in Michigan.

Adult-Use Legal Effective 2018

2.5 oz Adult-use possession limit

12 plants Home cultivation

Yes Medical patient housing protection

Federal baseline (uniform in Michigan): Cannabis remains a Schedule I controlled substance under 21 U.S.C. § 812(c) Schedule I(c)(10) regardless of Michigan's legalization status. HUD PIH Notice 2014-21 (re-issued PIH 2017-13) requires Public Housing Authorities to deny admission to public housing or HCV (Section 8) for any household member illegally using a controlled substance, including cannabis. Landlords may prohibit smoking of any substance as a private property interest in any state.

Recreational cannabis has been legal for Michigan adults 21 and older since the Michigan Regulation and Taxation of Marihuana Act (MRTMA), Initiated Law 1 of 2018, took effect in December 2018. Medical use has been legal even longer, since the Michigan Medical Marihuana Act of 2008. But legalization does not strip landlords of control over their buildings. The MRTMA expressly preserves an owner's authority to regulate cannabis on the property, with one narrow carve-out that trips up landlords who write blanket bans.

The rule that matters most for lease drafting lives in MCL 333.27954: you can prohibit smoking and cultivation, but you cannot forbid a tenant from lawfully possessing and consuming cannabis by means other than smoking. And for any property tied to federal housing dollars, none of Michigan's legalization applies the way tenants assume, because cannabis is still a Schedule I drug under federal law.

Michigan Cannabis Legal Status

Michigan is classified as Adult-Use Recreational Legal (effective 2018). The governing statute is MCL § 333.27951 et seq. (Proposal 1, 2018).

Landlord Authority in Michigan

Landlords retain ban authority.

MCL § 333.27955(2): a person who occupies, owns, or controls property may prohibit or regulate consumption, cultivation, or sale on the property. Highest home-grow limit in U.S.

Michigan's status: recreational and medical, with landlords still in control

Michigan is a fully legal state for adults 21 and older. Under MCL 333.27955, an adult may carry up to 2.5 ounces of marihuana (no more than 15 grams of which may be concentrate), keep up to 10 ounces at home, and cultivate up to 12 plants per residence for personal use. Home amounts over 2.5 ounces must be kept in a locked container.

Those are the tenant's rights against the state. They are not rights against a landlord. The MRTMA does not force any property owner to allow cannabis activity on rented premises. It simply says the state will not prosecute a compliant adult. What happens inside your unit is governed by your lease, subject to the one exception below.

What MCL 333.27954 lets you ban, and the one thing it doesn't

The governing sentence is in MCL 333.27954. It allows a person to "prohibit or otherwise regulate the consumption, cultivation, distribution, processing, sale, or display" of marihuana on property the person owns, occupies, or manages, except that a lease agreement may not prohibit a tenant from lawfully possessing and consuming marihuana by means other than smoking.

In plain terms for a Michigan landlord:

You can ban smoking. A no-smoking clause that covers marihuana is enforceable, the same as a tobacco smoke ban.
You can ban cultivation. Even though the state lets adults grow up to 12 plants, you may prohibit any grow in the unit. A lease ban overrides the tenant's state-level grow right.
You cannot ban lawful edibles, tinctures, or other non-smoked forms. A clause purporting to bar a tenant from possessing or consuming cannabis edibles is void as to that conduct. You can regulate the nuisance (odor, common areas), but you cannot forbid lawful non-smoking consumption inside the unit.

This is the trap in generic "no marijuana" lease language. A total prohibition is unenforceable to the extent it reaches lawful non-smoked use. Draft to the smoking-and-cultivation line the statute actually draws.

The federal conflict: Section 8, public housing, and Schedule I

Michigan legalization stops at the federal door. Cannabis remains a Schedule I controlled substance under the federal Controlled Substances Act, and HUD has not changed its position. For federally assisted housing, including the Housing Choice (Section 8) voucher program and public housing, HUD bars admission of new marijuana users and gives housing authorities discretion to terminate tenancy for use, medical or recreational.

If you accept Section 8 vouchers or manage HUD-subsidized units, you are operating under the federal baseline, not the MRTMA. A tenant's compliance with Michigan law is not a defense in that context. Owners of subsidized or federally financed property should keep an unambiguous no-cannabis policy and understand it is the federal program rules, not state law, that control there.

Medical cannabis tenants under the MMMA

The Michigan Medical Marihuana Act gives registered patients protections, but it does not override a written lease. The MMMA does not require a private property owner to lease residential property to a person who smokes or cultivates marihuana on the premises when the written lease prohibits that conduct.

So a medical card does not defeat a valid no-smoking or no-grow clause. What it does affect is your reasonable-accommodation posture: because federal law still classifies cannabis as illegal, most courts have not required landlords to accommodate cannabis use as a disability accommodation. Non-smoked medical consumption, however, falls under the same MCL 333.27954 carve-out as recreational, so a blanket ban on a patient's edibles is no more enforceable than one on any other tenant's.

Drafting a lease clause that holds up in Michigan

Write to the statute, not around it. A defensible Michigan cannabis clause typically does the following:

Prohibits all smoking of any substance, including marihuana and tobacco, inside the unit and common areas, and treats the odor as a lease violation and potential nuisance.
Prohibits cultivation of marihuana plants anywhere on the premises.
Preserves the tenant's right to lawfully possess and consume non-smoked cannabis, so the clause is not void for overreaching.
Reserves nuisance and property-damage remedies, so odor, moisture from a grow, or disturbance to other tenants remains actionable regardless of legality.
For subsidized property, states an outright no-cannabis policy grounded in federal program rules.

Because enforceability turns on the exact wording, and because federally assisted units follow a different rulebook, have Michigan counsel review your form lease before you rely on it.

Medical Patient Housing Rules in Michigan

Michigan protects registered medical cannabis patients in housing.

Under MCL § 333.27951 et seq. (Proposal 1, 2018), a landlord may not refuse to rent to or evict a registered medical patient solely because of their medical-use status. However, three significant carve-outs apply:

Federal subsidy override. Anti-discrimination protection does NOT apply to federally subsidized housing, Section 8, public housing, project-based assistance, or any program receiving federal funds. HUD PIH 2014-21 controls.
Smoking ban still permissible. Most state medical-patient protections still allow landlords to prohibit smoking on the premises. Patients must use edibles, tinctures, or vaporizers in non-smoking settings.
On-premises consumption limits. Some statutes restrict the protection to off-premises use only, leaving on-premises consumption subject to the lease.

Section 8 / HCV in Michigan, The Federal Trap

HUD PIH 2014-21 mandatory denial applies in Michigan. Even though Michigan has legalized adult-use cannabis, a Public Housing Authority in Michigan must deny admission to any household where a member illegally uses a controlled substance, and cannabis remains federal-illegal. Existing Section 8 tenants who use cannabis may face termination at PHA discretion, though termination is not mandatory like denial is.

The practical impact: a tenant holding a Housing Choice Voucher who tests positive for cannabis or self-discloses use during recertification can lose their voucher in Michigan, regardless of any state cannabis legalization or medical card status. This is the single most common point of confusion for tenants in adult-use states.

Frequently Asked Questions

Can a Michigan landlord ban marijuana in the lease?

Partly. Under MCL 333.27954 you can prohibit smoking marihuana and cultivating plants, but you cannot prohibit a tenant from lawfully possessing and consuming cannabis by non-smoking means such as edibles or tinctures. A blanket total ban is unenforceable to that extent.

Can I stop a tenant from growing cannabis in a rental?

Yes. Michigan lets adults grow up to 12 plants per residence for personal use under MCL 333.27955, but that state right does not override a lease. A no-cultivation clause is enforceable, and growing in violation of it is grounds for a lease action.

Does a medical marijuana card override my no-smoking clause?

No. The Michigan Medical Marihuana Act does not require an owner to lease to someone who smokes or cultivates on the premises when the written lease prohibits it. A card does not defeat a valid no-smoking or no-grow clause.

How does this work with Section 8 or public housing?

Differently. Cannabis is still a Schedule I drug federally, and HUD bars new marijuana users from federally assisted housing and lets housing authorities evict for use. In Section 8 or HUD-subsidized units, federal rules control, not Michigan's MRTMA, so a tenant's state-law compliance is not a defense.

How much cannabis can a Michigan tenant legally have?

Under MCL 333.27955, an adult 21 or older may carry up to 2.5 ounces (no more than 15 grams as concentrate) and keep up to 10 ounces at home, with amounts over 2.5 ounces in a locked container. These are limits against the state, not against your lease terms.

Can I charge extra or evict over cannabis odor?

You can treat smoke and persistent odor as a lease violation and a nuisance if your lease bans smoking, since MCL 333.27954 permits a smoking prohibition. You cannot penalize a tenant for lawful non-smoked consumption alone, but you can enforce nuisance and property-damage terms.

Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: MCL § 333.27951 et seq. (Proposal 1, 2018). Last updated October 24, 2026. For informational purposes only, not legal advice.
