Landlord ban authority, possession and home-grow limits, medical patient housing rules, and federal Section 8 restrictions in Utah.
Utah is one of the strictest states in the country on cannabis, which works in a landlord's favor. Recreational marijuana is illegal for all purposes, and even the medical program bans smoking and home cultivation. That leaves you broad authority to prohibit cannabis in your units, with no state mandate forcing you to accommodate a tenant's use. The one real trap is federal: any tenant in Section 8 or public housing is subject to a stricter rule that overrides Utah's medical carve-out entirely.
Utah is classified as Medical Cannabis Only (effective 2018). The governing statute is Utah Code § 26B-4-201 (Prop 2 / HB 3001, 2018).
No home cultivation. No smokable flower (vape/edibles only). Medical patients protected from housing discrimination per § 26B-4-205.
Utah has no recreational market. Possessing, using, growing, or selling marijuana for recreational purposes is illegal, and possession of less than 1 ounce is a misdemeanor carrying up to 6 months in jail. The only lawful path is the Utah Medical Cannabis Act, codified at Utah Code Title 26B, Chapter 4, Part 2, with the patient possession exemption at Utah Code 58-37-3.9. Only registered patients (generally age 21 and older, or minors with a designated guardian caregiver) may buy from a licensed pharmacy. The program is large — more than 112,000 active patients served through 15 licensed pharmacies — so you will encounter cardholding tenants, but their card does not give them a right to consume however they wish on your property.
Two features of Utah's program matter enormously for rental owners. First, smoking marijuana is prohibited even for registered patients. Raw flower is a legal form, but it may only be vaporized in a device that heats without a flame — combustion is not allowed, and edible products like candies, cookies, and brownies are not permitted forms at all. Second, home cultivation is illegal for everyone in Utah, including patients and caregivers. That means a tenant growing plants in your unit is breaking state law regardless of any medical card, giving you clear grounds to act. You do not have to build a smoking or cultivation carve-out into your policy — Utah already forbids both.
Utah landlord-tenant law expressly lets your rental agreement set the rule. Under Utah Code 57-22-5 and 57-22-4, a lease may prohibit or allow smoking of tobacco or other products in the unit or on the premises. A clear written no-smoking, no-vaping, and no-cannabis clause is enforceable, and a medical cannabis card does not exempt a tenant from it. Utah's medical-use protection removes criminal liability for the patient; it does not compel a private landlord to permit use on the property. Write the clause to cover smoking, vaping, and cultivation explicitly, define the enclosed unit and common areas, and state the consequence for violation so enforcement is straightforward.
If you accept a Section 8 Housing Choice Voucher or operate public housing, federal law overrides Utah's medical carve-out. Marijuana is still a Schedule I substance under the federal Controlled Substances Act, illegal for every purpose. Federal rules require public housing authorities to deny admission to current illegal-drug users, including state-registered medical patients, and permit termination of assistance for cannabis use on the premises. There is no medical exception in the federal program. A tenant with a valid Utah card is still using an illegal substance in the eyes of HUD, so in assisted units the answer is uniform: cannabis is not allowed.
Keep enforcement clean. Base any action on the conduct — smoke odor, combustion, visible plants, damage — not on a tenant's medical status. Do not demand to see a tenant's medical cannabis card or physician recommendation; requiring proof of a medical condition can expose you to a disability-discrimination claim. If a non-smoking tenant complains about drifting smoke, note that Utah's nuisance law (Utah Code Title 78B, Chapter 6, Part 11) treats drifting tobacco smoke as a nuisance in limited circumstances, which can give the affected tenant a cause of action — another reason a firm building-wide no-smoking policy protects you on both sides.
Under Utah Code § 26B-4-201 (Prop 2 / HB 3001, 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:
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 Utah, 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.

This overview reflects Utah statutes in effect as of 2026, including the Utah Medical Cannabis Act (Utah Code Title 26B, Chapter 4), the patient possession exemption at Utah Code 58-37-3.9, landlord-tenant provisions at Utah Code 57-22-4 and 57-22-5, and the nuisance provisions at Utah Code Title 78B, Chapter 6, Part 11. Federal treatment of marijuana under the Controlled Substances Act and HUD assisted-housing rules is summarized as the controlling baseline for Section 8 and public housing. Statutes and program rules change; confirm the current code text at le.utah.gov and consult a Utah attorney before acting on a specific tenant matter.

Yes. Utah Code 57-22-5 and 57-22-4 let your lease prohibit smoking and other use in the unit and on the premises, and a medical cannabis card does not override that clause. State medical protection only removes criminal liability for the patient; it does not require a private landlord to permit use on the property.
No. Recreational possession, use, cultivation, and sale are all illegal in Utah. Possession of less than 1 ounce is a misdemeanor punishable by up to 6 months in jail. Only registered medical patients may lawfully obtain cannabis, and only from a licensed pharmacy.
Not by smoking flower — Utah's medical program prohibits smoking marijuana even for patients; flower may only be vaporized without a flame. On top of that, your lease can ban vaping and use entirely, and the patient's card does not exempt them from that policy.
No. Home cultivation is illegal in Utah for everyone, including registered patients and caregivers. A tenant growing plants is violating state law regardless of any medical card, giving you clear grounds to enforce your lease and pursue eviction for the violation.
Federal law controls there and is stricter than Utah's. Marijuana is a Schedule I substance under the federal Controlled Substances Act, so public housing authorities must deny admission to current cannabis users and may terminate assistance for use — with no medical exception, even for a valid Utah card.
It is risky. Demanding to see a card or physician recommendation can be treated as probing a disability and may expose you to a discrimination claim. Enforce based on observed conduct — odor, combustion, plants, or damage — rather than on a tenant's medical status.
Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: Utah Code § 26B-4-201 (Prop 2 / HB 3001, 2018). Last updated July 14, 2026. For informational purposes only, not legal advice. Cannabis law is rapidly evolving and federal/state conflict creates significant compliance risk; consult a licensed Utah attorney before making a lease, screening, or eviction decision involving cannabis.
