Cannabis & Marijuana Rental Rules in Ohio 2026

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

Adult-Use Legal Effective 2023

2.5 oz Adult-use possession limit

6 plants Home cultivation

Yes Medical patient housing protection

Federal baseline (uniform in Ohio): Cannabis remains a Schedule I controlled substance under 21 U.S.C. § 812(c) Schedule I(c)(10) regardless of Ohio'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 adults 21 and older in Ohio since voters passed Issue 2 in November 2023. As of March 20, 2026, the rules live in Ohio Revised Code Chapter 3796 (the Marijuana Control Law), which absorbed the former Chapter 3780 when Senate Bill 56 took effect. For landlords, the practical takeaway is favorable: Ohio law lets you ban cannabis smoking, vaping, and home cultivation on your property, but the ban only works if it is written into the lease.

Legalization did not strip landlords of control over their buildings. It did, however, add one guardrail on tenant screening and left the federal conflict fully intact for any property tied to Section 8 or public housing. This page breaks down exactly where your authority begins and ends.

Ohio Cannabis Legal Status

Ohio is classified as Adult-Use Recreational Legal (effective 2023). The governing statute is O.R.C. § 3780 (Issue 2, 2023).

Landlord Authority in Ohio

Landlords retain ban authority.

O.R.C. § 3780.01(B)(8): landlord may prohibit consumption, smoking, and cultivation on rental property. Medical patients protected under § 3796.28.

Where Ohio stands: legal, but landlord-controllable

Ohio is a full adult-use state. Adults 21 and older may possess up to 2.5 ounces of plant material and up to 15 grams of cannabis extract, purchased from a licensed Ohio dispensary or grown legally at home. The medical program and the adult-use program now sit together under ORC Chapter 3796 after Senate Bill 56 repealed the standalone adult-use Chapter 3780 on March 20, 2026.

None of this obligates you to permit cannabis on your property. Ohio's statute deliberately preserves landlord authority: the same law that legalized consumption also spells out that a landlord may restrict it by lease. Product from another state remains contraband even for a legal Ohio consumer, and cannabis is still illegal under federal law, the pivot point for any federally assisted unit.

Banning smoking, vaping, and combustion by lease

Under Chapter 3796, a landlord may prohibit a tenant from consuming cannabis by smoking, combustion, or vaporization on the premises, but only if that prohibition is stated in the lease. SB 56 broadened the earlier language, which covered smoking and combustion, to expressly include vaporization, so a modern no-smoking clause should name vaping as well to close the gap.

If your lease is silent, you have not banned anything. A generic "no smoking" clause that predates legalization is worth updating to reference cannabis smoke, combustion, and vaporization by name. For multi-unit buildings, a combustion ban is also defensible on fire-safety and shared-air grounds, and applying it uniformly to tobacco and cannabis keeps enforcement clean.

Home cultivation: six plants, and your right to say no

Ohio law lets an adult grow up to 6 cannabis plants at a primary residence, capped at 12 plants where two or more adults 21 or older live. Plants must be in a secured, enclosed area not accessible to anyone under 21 and not visible from public spaces. Exceeding the limit is charged as illegal cultivation of marijuana, a stiffer offense after SB 56.

Cultivation is exactly the kind of activity a landlord will often want to prohibit, given moisture, electrical load, odor, and insurance concerns. Chapter 3796 permits a landlord to ban home cultivation outright, again, only when the prohibition appears in the lease. A clear no-cultivation clause is the cleanest way to keep grow operations out of your units.

The one screening limit: don't reject a consumer for consuming

Ohio added a narrow tenant-screening guardrail. A landlord may not reject an applicant solely or primarily because the person is an adult-use cannabis consumer, or, on the medical side, because the person is a registered patient or caregiver, unless the rejection is required by federal law.

This is not a broad protected class. It bars using cannabis-consumer status by itself as the reason to deny an applicant; it does not stop you from denying for credit, income, rental history, or a violated no-smoking/no-cultivation lease term. The federal-law carve-out is what makes federally assisted properties different, covered next.

Section 8 and public housing: federal law still controls

Cannabis remains a Schedule I substance under the federal Controlled Substances Act, and that governs any federally assisted housing. HUD prohibits marijuana use in public housing and Section 8/Housing Choice Voucher units. Owners must deny admission to new households whose members use marijuana and may terminate assistance or tenancy for use, regardless of Ohio's legalization.

For a Section 8 landlord, this is the scenario where the federal-law exception in Ohio's anti-discrimination rule applies: rejecting or removing a cannabis-using household is not prohibited state discrimination when federal law compels it. If you mix voucher and market-rate units, keep the cannabis policies for federally assisted units clearly separate and documented.

Medical Patient Housing Rules in Ohio

Ohio protects registered medical cannabis patients in housing.

Under O.R.C. § 3780 (Issue 2, 2023), 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 Ohio, The Federal Trap

HUD PIH 2014-21 mandatory denial applies in Ohio. Even though Ohio has legalized adult-use cannabis, a Public Housing Authority in Ohio 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 Ohio, 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 an Ohio landlord ban marijuana smoking in a rental?

Yes. Under ORC Chapter 3796, a landlord may prohibit consumption by smoking, combustion, or vaporization if the prohibition is written into the lease. A silent lease bans nothing, so add a clause that names cannabis smoke, combustion, and vaping.

Can I prohibit tenants from growing cannabis?

Yes. Ohio allows a landlord to ban home cultivation as long as the prohibition is in the lease. State law otherwise permits an adult to grow up to 6 plants (12 per household with two or more adults 21+) in a secured, enclosed area at their primary residence.

Can I refuse to rent to someone because they use marijuana?

Not on that basis alone. Ohio bars rejecting an applicant solely or primarily because they are an adult-use consumer or a registered medical patient/caregiver, unless federal law requires the rejection. You can still deny for credit, income, rental history, or a violated lease term.

How does this work for Section 8 or public housing?

Differently. Cannabis is illegal under federal law (Schedule I), and HUD prohibits marijuana use in public housing and Section 8/Housing Choice Voucher units. Owners must deny new households that use marijuana and may terminate for use, regardless of Ohio law. The federal-law exception in Ohio's rule applies here.

What are the possession and age limits in Ohio?

Adults 21 and older may possess up to 2.5 ounces of plant material and up to 15 grams of cannabis extract, obtained from a licensed Ohio dispensary or grown legally at home. Product brought in from another state is contraband.

Did the law change in 2026?

Yes. Senate Bill 56 took effect March 20, 2026, repealing the former Chapter 3780 and consolidating adult-use and medical marijuana under ORC Chapter 3796. It also expressly added vaporization to the consumption a landlord can ban by lease.

Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: O.R.C. § 3780 (Issue 2, 2023). Last updated October 24, 2026. For informational purposes only, not legal advice.
