Landlord ban authority, possession and home-grow limits, medical patient housing rules, and federal Section 8 restrictions in Connecticut.
Connecticut is one of a small group of states that wrote tenant cannabis rights directly into its landlord-tenant code. Recreational cannabis has been legal for adults 21 and older since July 1, 2021, under the Responsible and Equitable Regulation of Adult-Use Cannabis Act (RERACA, Public Act 21-1). More important for property owners, RERACA added Conn. Gen. Stat. Sec. 47a-9a, which sets a hard line most landlords get wrong: you can ban smoking cannabis, but you cannot ban a tenant from possessing or consuming it. That distinction, plus a carve-out for federally assisted housing, drives every lease decision below.
Connecticut is classified as Adult-Use Recreational Legal (effective 2021). The governing statute is Conn. Gen. Stat. § 21a-422a et seq. (SB 1201, 2021).
CGS § 21a-422g: landlord may prohibit smoking and cultivation. CGS § 21a-408p protects medical patients from discrimination unless property is federally subsidized.
Conn. Gen. Stat. Sec. 47a-9a states plainly that a landlord or property manager may not prohibit the possession of cannabis or the consumption of cannabis in a rental unit. The single exception written into the statute is that a landlord may prohibit the smoking of cannabis and the use of an electronic cannabis delivery device or cannabis vapor product (as those terms are defined in Sec. 19a-342a).
In practice this means a Connecticut tenant is legally entitled to keep cannabis in the unit and to consume it in non-smoked forms, edibles, tinctures, capsules, no matter what your lease says. A lease clause purporting to bar all cannabis "possession or use" is unenforceable to the extent it reaches beyond smoking and vaping. What you retain is real and enforceable: a no-smoking policy that covers combusted cannabis and vapor products exactly the way it covers lit tobacco.
Because the statute permits a smoking ban but not a possession ban, your lease language has to be precise. Draft the restriction around the method of use, not the substance. A clause that prohibits "smoking or vaping of any substance, including tobacco and cannabis, inside the dwelling unit and on the premises" tracks Sec. 47a-9a and Sec. 19a-342a and will hold up.
Avoid blanket language such as "no marijuana on the premises" or "tenant shall not possess or use cannabis", those provisions conflict with the statute and expose you to a discrimination or unfair-practice claim. Apply the smoking rule uniformly to all tenants and all combustible or aerosolized products so it reads as a legitimate air-quality and fire-safety policy rather than cannabis-specific targeting. Odor, smoke damage, and lease violations tied to smoking remain valid grounds for action; the mere presence of cannabis or evidence of edible use is not.
The most important carve-out is federal. Sec. 47a-9a expressly does not apply where allowing possession or consumption would violate federal law or regulations, or would cause the landlord to lose a monetary or licensing-related benefit under federal law. That exception exists because cannabis remains a Schedule I controlled substance under the federal Controlled Substances Act (21 U.S.C. 812), and legalization in Connecticut does not change federal housing rules.
For public housing and Housing Choice Voucher (Section 8) units, HUD requires housing authorities to deny admission to any household with a member who is a current user of a controlled substance, including marijuana (42 U.S.C. 13661). Current cannabis use is grounds for denial or termination in federally assisted housing regardless of RERACA. Separately, HUD's 2018 smoke-free rule requires every public housing agency to bar lit tobacco products in units and common areas. If you accept vouchers or operate assisted units, follow the federal standard, the state possession protection yields to it.
Home cultivation is now legal statewide. Since July 1, 2023, any adult 21 or older may grow up to 6 plants (no more than 3 mature at once), capped at 12 plants per household; registered medical patients gained grow rights earlier, on October 1, 2021. RERACA requires that plants be grown out of public view and secured against access by anyone under 21. Sec. 47a-9a's protection covers possession and consumption but is silent on cultivation, so a landlord may reasonably address grow operations through lease terms tied to legitimate concerns, humidity and mold, electrical load, water damage, and secured access, provided the clause is not a pretext for banning lawful possession.
Adults may possess up to 1.5 ounces on their person and up to 5 ounces stored at home or locked in a vehicle trunk or glovebox. These caps matter when a possession dispute arises: amounts within the limits are lawful and protected; amounts beyond them, or any sale, are not.
RERACA also limits screening. Under Sec. 47a-9a, a Connecticut landlord may not refuse to rent to, or otherwise discriminate against, a current or prospective tenant based on a past conviction for possession of a cannabis-type substance under Sec. 21a-279a, or for a past conviction for possession of four or fewer ounces of cannabis plant material (including equivalent amounts and out-of-state equivalents).
If your tenant-screening process pulls criminal history, scrub low-level cannabis-possession convictions from your adverse-action logic. Denying an applicant on that basis is a statutory violation. This protection is separate from the possession/smoking rule and applies to every rental, including units where you lawfully prohibit smoking.
Under Conn. Gen. Stat. § 21a-422a et seq. (SB 1201, 2021), 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 Connecticut, 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 page summarizes Connecticut's Responsible and Equitable Regulation of Adult-Use Cannabis Act (Public Act 21-1) and Conn. Gen. Stat. Sec. 47a-9a, cross-referenced against the federal Controlled Substances Act (21 U.S.C. 812) and HUD admission rules (42 U.S.C. 13661) as they stood in 2026. It is written for Connecticut landlords and property managers as general information, not legal advice. Cannabis law and HUD guidance change; confirm current statutory text and consult a Connecticut landlord-tenant attorney before drafting lease clauses or taking adverse action, particularly for federally assisted or voucher-supported units where federal law overrides the state possession protection.
Only partially. Under Conn. Gen. Stat. Sec. 47a-9a you may prohibit smoking cannabis and using cannabis vapor products, but you cannot prohibit a tenant from possessing cannabis or consuming it in non-smoked forms such as edibles. A total ban on possession or use is unenforceable.
Yes. Sec. 47a-9a lets a landlord prohibit both the smoking of cannabis and the use of an electronic cannabis delivery device or cannabis vapor product, as defined in Sec. 19a-342a. Draft the clause to cover smoking and vaping of any substance.
No. Sec. 47a-9a does not apply where allowing possession would violate federal law or cost the landlord a federal benefit. Cannabis is still Schedule I federally (21 U.S.C. 812), and HUD requires denial of admission to current users under 42 U.S.C. 13661. In assisted housing, the federal rule controls.
State law allows adults 21+ to grow up to 6 plants (3 mature), capped at 12 per household, effective July 1, 2023, kept out of public view and secured from minors. Sec. 47a-9a does not shield cultivation, so a landlord may address grow-related risks like mold, electrical load, and water damage through reasonable lease terms.
No. Sec. 47a-9a prohibits refusing to rent based on a past conviction for cannabis possession under Sec. 21a-279a or for possessing four or fewer ounces of cannabis plant material. Remove those low-level convictions from your screening criteria.
Adults 21+ may possess up to 1.5 ounces on their person and up to 5 ounces stored at home or locked in a vehicle. Amounts within these limits are lawful and protected under Sec. 47a-9a; larger amounts or any sale are not.
Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: Conn. Gen. Stat. § 21a-422a et seq. (SB 1201, 2021). Last updated August 15, 2026. For informational purposes only, not legal advice. Cannabis law is rapidly evolving and federal/state conflict creates significant compliance risk; consult a licensed Connecticut attorney before making a lease, screening, or eviction decision involving cannabis.
