Cannabis & Marijuana Rental Rules in Arizona 2026

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

Adult-Use Legal Effective 2020

1 oz Adult-use possession limit

6 plants Home cultivation

Yes Medical patient housing protection

Federal baseline (uniform in Arizona): Cannabis remains a Schedule I controlled substance under 21 U.S.C. § 812(c) Schedule I(c)(10) regardless of Arizona'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 marijuana has been legal in Arizona for adults 21 and older since voters passed Proposition 207, the Smart and Safe Arizona Act, in November 2020, and medical use has been legal since the Arizona Medical Marijuana Act (AMMA) of 2010. Neither law strips landlords of control over their buildings. The recreational statute, ARS 36-2851, expressly preserves the right of anyone who "occupies, owns or controls" property to prohibit or regulate marijuana on it. In practice, an Arizona landlord can ban smoking, ban home cultivation, or ban cannabis entirely through the lease, and that clause is enforceable. The one hard limit runs the other way: for tenants who hold a state medical card, and for owners who take federal housing money, separate rules kick in.

Arizona Cannabis Legal Status

Arizona is classified as Adult-Use Recreational Legal (effective 2020). The governing statute is A.R.S. § 36-2851 et seq. (Prop 207, 2020).

Landlord Authority in Arizona

Landlords retain ban authority.

A.R.S. § 36-2851(B): landlord may prohibit smoking, vaporizing, and cultivation on rental property. Medical patient protections under § 36-2813.

Arizona's legal status: recreational and medical, with a property carve-out

Arizona sits in the fully legal column. Under ARS 36-2852, an adult 21 or older may possess up to 1 ounce of marijuana, of which no more than 5 grams may be concentrate, and may cultivate up to 6 plants at their primary residence (a maximum of 12 plants where two or more adults live together). Cultivation must occur in an enclosed, locked area not visible from public view. Smoking in a public place or open space remains prohibited.

What matters for landlords is the carve-out in ARS 36-2851: legalization "does not restrict" a person or entity that occupies, owns, or controls property from prohibiting or regulating marijuana conduct on that property. A rental unit is the landlord's property. That single sentence is the legal foundation for every cannabis clause an Arizona landlord writes.

Can an Arizona landlord ban smoking and home-growing?

Yes, on both counts. Arizona landlords have long been free to make a unit smoke-free, and that authority covers marijuana smoke and vapor exactly the way it covers tobacco. Because ARS 36-2851 lets the property owner regulate marijuana conduct, a lease can go further and prohibit cultivation outright, even though the state otherwise permits a 6-plant home grow. A tenant's right to grow under ARS 36-2852 is a right against the state, not a right against a private landlord who has contracted otherwise.

Practical drafting notes: a generic "no smoking" clause reaches marijuana smoke, but it does not reach edibles or other odorless consumption. If you want to keep cannabis out of the unit entirely, say so, and address possession, cultivation, and smoke/vapor as separate items. Cannabis clauses in Arizona rest on ordinary lease and contract law layered on the Arizona Residential Landlord and Tenant Act (ARS Title 33, Chapter 10); there is no special rental-cannabis statute to satisfy.

The medical cardholder exception you can't ignore

The AMMA adds a wrinkle that recreational law does not. Under ARS 36-2813, a landlord may not refuse to lease to, or otherwise penalize, a person solely because of their status as a registered qualifying patient or caregiver. You cannot turn away an applicant just for holding a card.

That protection is narrower than it looks. It bars discrimination based on card status; it does not force you to allow use inside the unit. A landlord can still enforce a no-smoking or no-cultivation clause against a cardholder, because banning smoke is not the same as penalizing someone for holding a card. And ARS 36-2813 contains its own escape hatch: the anti-discrimination duty does not apply where honoring it would cost the landlord a monetary or licensing-related benefit under federal law, which is the doorway to the Section 8 problem below.

The federal Section 8 and public housing conflict

Marijuana is still a Schedule I controlled substance under the federal Controlled Substances Act, illegal nationwide regardless of Arizona law. That gap controls federally assisted housing. For the Section 8 Housing Choice Voucher program, public housing, and project-based rental assistance, HUD rules govern. Federal law (42 U.S.C. 13661 and 13662) requires public housing authorities to deny admission to a household with a member engaged in current illegal drug use, and HUD treats state-legal marijuana as illegal drug use. So an applicant using cannabis, medical card or not, can be turned away from subsidized housing.

For tenants already housed, HUD gives the housing authority discretion: current marijuana users may be evicted, but a PHA is generally not required to terminate an existing lease solely for it. If you own or manage federally assisted units, your cannabis policy is set by HUD and your PHA contract, not by Prop 207. This is also exactly the federal-benefit scenario that switches off the AMMA anti-discrimination rule in ARS 36-2813.

Enforcement: what happens when a tenant violates the clause

If a tenant breaches an enforceable no-smoking or no-cannabis clause, you handle it as an ordinary lease violation under the Arizona Residential Landlord and Tenant Act, typically a written notice giving the tenant a chance to cure, followed by termination and, if needed, a forcible-detainer (eviction) action. Document the odor, damage, or plant activity; a written lease clause plus a paper trail is what wins these cases.

Keep two things separate. State civil penalties for breaking the recreational rules themselves (for example, cultivating outside the allowed conditions) live in ARS 36-2853 and are enforced by the state, not by you. Your remedy as a landlord is contractual, through the lease. A well-drafted clause is worth far more than any statute here, because Arizona hands the drafting authority directly to the property owner.

Medical Patient Housing Rules in Arizona

Arizona protects registered medical cannabis patients in housing.

Under A.R.S. § 36-2851 et seq. (Prop 207, 2020), 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 Arizona, The Federal Trap

HUD PIH 2014-21 mandatory denial applies in Arizona. Even though Arizona has legalized adult-use cannabis, a Public Housing Authority in Arizona 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 Arizona, 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.

It is general information for landlords, not legal advice. Cannabis law sits at a live conflict between state legalization and continued federal prohibition; before drafting or enforcing a cannabis clause, or setting policy for federally assisted units, confirm current statute and consult an Arizona attorney.

Frequently Asked Questions

Can an Arizona landlord ban marijuana even though it's legal?

Yes. Proposition 207 legalized recreational marijuana for adults 21 and older, but ARS 36-2851 expressly preserves the right of anyone who owns or controls property to prohibit or regulate marijuana on it. A lease clause banning smoking, cultivation, or cannabis entirely is enforceable.

Can I refuse to rent to a medical marijuana cardholder in Arizona?

Generally no. Under ARS 36-2813, a landlord cannot refuse to lease to or penalize someone solely because they are a registered qualifying patient or caregiver. The exception: if honoring that duty would cost you a federal monetary or licensing benefit, such as HUD subsidy, it does not apply.

Does a no-smoking clause cover marijuana in Arizona?

Yes for smoke and vapor. A no-smoking clause reaches marijuana smoke the same way it reaches tobacco. It does not reach edibles or other odorless use, so if you want cannabis out of the unit entirely, ban possession, cultivation, and smoke/vapor as separate lease items.

How many marijuana plants can an Arizona tenant grow?

Under ARS 36-2852, an adult 21+ may grow up to 6 plants at their primary residence, with a maximum of 12 plants per household of two or more adults, in an enclosed, locked area not visible to the public. A landlord may still prohibit cultivation entirely by lease.

Can Section 8 or public housing tenants use marijuana in Arizona?

No. Marijuana remains a Schedule I controlled substance federally. Under 42 U.S.C. 13661 and HUD rules, public housing authorities must deny admission to current marijuana users, medical card or not. Existing tenants may be evicted at the housing authority's discretion.

Is there a special Arizona statute about cannabis in leases?

No. Arizona has no standalone rental-cannabis statute. Landlord authority comes from the property-control carve-out in ARS 36-2851 (recreational) and the AMMA framework in ARS 36-2813, applied on top of ordinary lease law and the Arizona Residential Landlord and Tenant Act, ARS Title 33, Chapter 10.

Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: A.R.S. § 36-2851 et seq. (Prop 207, 2020). 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 Arizona attorney before making a lease, screening, or eviction decision involving cannabis.
