Cannabis & Marijuana Rental Rules in Kansas 2026

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

CBD/Low-THC Effective 2019

Adult-use possession limit

Banned Home cultivation

No Medical patient housing protection

Federal baseline (uniform in Kansas): Cannabis remains a Schedule I controlled substance under 21 U.S.C. § 812(c) Schedule I(c)(10) regardless of Kansas'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.

Kansas is one of the most restrictive cannabis states in the country, and that makes a landlord's position unusually clean. Marijuana is a Schedule I controlled substance under K.S.A. 65-4105, there is no recreational market, and there is no operational medical marijuana program. The only carve-out is a narrow affirmative defense for a specific low-THC CBD oil. Because no Kansas statute protects a tenant's cannabis use, you can prohibit possession, smoking, and cultivation outright in the lease and enforce it like any other lease violation.

The practical risks for Kansas landlords are the usual ones, smoke migration, odor complaints, guest conduct, and cultivation damage, not a tangle of medical-use accommodation rules. This guide covers the current legal status, your authority to restrict, the lease language that holds up, and the one place where federal rules override everything: federally assisted housing.

Kansas Cannabis Legal Status

Kansas is classified as Low-THC / CBD Only (effective 2019). The governing statute is K.S.A. § 21-5701 (Claire & Lola's Law, 2019).

Landlord Authority in Kansas

Cannabis is restricted in Kansas.

CBD ≤5% THC permitted with affirmative defense for limited conditions. Recreational marijuana fully illegal.

Cannabis is illegal in Kansas, recreational and medical

Kansas has not legalized marijuana in any form for general use. It remains a Schedule I substance under K.S.A. 65-4105, and possession is a crime under K.S.A. 21-5706. A first possession offense is a Class B nonperson misdemeanor carrying up to 6 months in jail and a fine of up to $1,000; a second offense is a Class A misdemeanor with up to 1 year and up to $2,500; a third or later offense becomes a drug severity level 5 felony. Cultivation is charged as a felony under K.S.A. 21-5705, with penalties that scale by plant count.

There is no medical marijuana program to accommodate. The 2025-26 legislature filed several cannabis measures, including SB 294, but adjourned on April 10, 2026 without advancing any of them. For a Kansas landlord, this means cannabis use on your property is not merely a lease matter; it is unlawful conduct under state law, which strengthens your enforcement position.

The only exception: Claire and Lola's Law CBD oil

The one narrow opening is Claire and Lola's Law (K.S.A. 65-6235), enacted in 2019. It creates an affirmative defense, not a possession right, for a "CBD treatment preparation," defined as a CBD-rich oil with a THC concentration of no more than 5% relative to the CBD concentration. To raise the defense, a person must carry a letter from a Kansas-licensed physician, on letterhead, dated within the last 15 months, stating a debilitating medical condition.

This is not a smokable product and it is not a shield against a lease clause. Separately, CBD products with zero percent THC are excluded from the criminal definition of marijuana and are legal in Kansas. For your purposes: a tenant using zero-THC CBD or a Claire and Lola's oil is not smoking anything and creates no odor or combustion risk, so a well-drafted "no smoking, no cultivation, no illegal drugs" clause reaches the conduct you actually care about without needing a cannabis-specific carve-out.

Your authority to ban smoking and cultivation

Kansas imposes no statutory limit on a landlord's right to prohibit smoking, tobacco, vaping, or cannabis, inside a unit or on the property. That authority comes from the lease, so it only exists if you write it in. Because there is no state medical-cannabis program and no housing anti-discrimination provision for cannabis users, you are not required to accommodate any tenant's marijuana or smoking preference.

Cultivation deserves its own clause. Even a small indoor grow raises humidity, invites mold, draws pests, overloads circuits, and, in Kansas, is a felony. Prohibit cultivation, propagation, and manufacture explicitly rather than relying on a general "lawful use" clause, so there is no ambiguity if you find plants or equipment during an inspection.

Lease clauses that hold up in Kansas

Because state law is on your side, the goal is clarity and consistent enforcement, not clever drafting. Effective Kansas leases typically include:

A no-smoking clause that names cigarettes, vaping, and cannabis, and covers the unit, balconies, and common areas, so smoke-migration and odor complaints have a written basis.
A no-illegal-drugs clause tying possession, use, sale, or manufacture of any controlled substance to a curable or terminable lease violation.
A no-cultivation clause barring growing, propagating, or processing cannabis or any controlled substance on the premises.
A guest-conduct clause making the tenant responsible for guests' compliance.

Apply these clauses uniformly to every tenant. Enforce through your normal Kansas notice-and-remedy process for lease breaches, and document odor, smoke, or cultivation evidence the same way you would any other violation.

Federally assisted housing: the federal ban controls

In Section 8 and public housing, federal law is stricter than anything the lease adds. Marijuana remains a Schedule I substance under the federal Controlled Substances Act, and HUD guidance directs public housing authorities to deny admission to current marijuana users, including those in states with legal medical or recreational programs. Kansas's illegality only reinforces that; there is no state medical status that could ever create a conflict here.

For existing federally assisted tenants, HUD gives housing authorities discretion on continued occupancy for drug use, but admission of a known marijuana user is prohibited. If you accept Housing Choice Vouchers or operate assisted units, treat marijuana as a categorical admissions bar regardless of any medical claim, and follow HUD and your PHA's policies rather than state law alone.

Medical Patient Housing Rules in Kansas

Kansas does not have statewide medical patient housing protection.

Medical cannabis patients in Kansas may be treated identically to recreational users by landlords. There is no state-law anti-discrimination requirement; the federal Schedule I framework controls. Some local jurisdictions may have ordinances providing limited protection, check the city or county where the rental unit is located.

Section 8 / HCV in Kansas, The Federal Trap

HUD PIH 2014-21 mandatory denial applies in Kansas. Even though Kansas has restricted cannabis, a Public Housing Authority in Kansas 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 Kansas, 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

Is marijuana legal in Kansas in 2026?

No. Marijuana is a Schedule I controlled substance under K.S.A. 65-4105, with no recreational market and no operational medical program. Possession is a crime under K.S.A. 21-5706, a first offense carries up to 6 months in jail and up to a $1,000 fine. The 2025-26 legislature filed bills such as SB 294 but adjourned on April 10, 2026 without legalizing anything.

Can a Kansas landlord ban marijuana and smoking in the lease?

Yes, without limitation. Kansas has no statute protecting a tenant's cannabis use or restricting a landlord's right to prohibit smoking. You can ban possession, use, smoking, and cultivation of marijuana in the lease and enforce it as a lease violation.

What about a tenant with a medical CBD recommendation?

Kansas has no medical marijuana program to accommodate. Claire and Lola's Law (K.S.A. 65-6235) only creates an affirmative defense for a low-THC CBD oil, no more than 5% THC relative to CBD, for someone carrying a Kansas physician's letter dated within the last 15 months. It is not a possession right and does not override a lease clause. Zero-THC CBD is legal and involves no smoking.

Can I prohibit tenants from growing cannabis?

Yes, and you should say so explicitly. Cultivation is a felony under K.S.A. 21-5705, and even a small grow risks mold, pests, and electrical overload. A dedicated no-cultivation clause removes any ambiguity if you find plants or equipment during a lawful inspection.

Do the rules change for Section 8 or public housing?

Yes, federal rules are stricter. Marijuana is Schedule I under the federal Controlled Substances Act, and HUD directs housing authorities to deny admission to current marijuana users. Because Kansas prohibits marijuana anyway, there is no state medical status that could conflict; treat marijuana as a categorical admissions bar in assisted housing.

How do I enforce a no-cannabis clause in Kansas?

Treat it like any other lease breach. Document odor, smoke migration, or cultivation evidence, then use your standard Kansas notice-and-remedy process for lease violations. Apply the clause uniformly to every tenant so enforcement is consistent and defensible.

Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: K.S.A. § 21-5701 (Claire & Lola's Law, 2019). Last updated October 24, 2026. For informational purposes only, not legal advice. Cannabis law is rapidly evolving and federal/state conflict creates significant compliance risk; consult a licensed Kansas attorney before making a lease, screening, or eviction decision involving cannabis.
