Federal baseline (uniform in Rhode Island): Cannabis remains a Schedule I controlled substance under 21 U.S.C. § 812(c) Schedule I(c)(10) regardless of Rhode Island'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 Rhode Island since the Rhode Island Cannabis Act was signed in May 2022 (R.I. Gen. Laws ch. 21-28.11). For landlords, legalization did not erase your control over the property, but it did draw a specific line that Rhode Island wrote into statute: you can ban smoking, and you cannot ban edibles. The distinction between combusted and non-combusted use is the single most important thing to get right in a Rhode Island lease, and it is unusual enough that many out-of-state form leases handle it wrong.

The other half of the picture is federal. Cannabis is still a Schedule I controlled substance under federal law, which means the rules flip entirely once a unit is tied to Section 8 vouchers or public housing. This page separates the two so you can write a lease that holds up in a Rhode Island district court.

Rhode Island Cannabis Legal Status

Rhode Island is classified as Adult-Use Recreational Legal (effective 2022). The governing statute is R.I. Gen. Laws § 21-28.11 (Cannabis Act, 2022).

Landlord Authority in Rhode Island

Landlords retain ban authority.

R.I. Gen. Laws § 21-28.11-29: landlord may prohibit consumption and cultivation on rental property. Medical patients protected under § 21-28.6-4(d).

Cannabis is legal in Rhode Island, with defined possession and grow limits

Rhode Island permits adults 21 and older to possess up to 1 ounce of cannabis on their person and up to 10 ounces in the home per resident, plus any lawfully grown live plants (R.I. Gen. Laws 21-28.11-22). Home cultivation is capped at three mature and three immature plants per dwelling unit, not per person. Medical marijuana has been legal in the state for longer than adult use.

These limits matter to landlords for two reasons. First, a tenant growing within the legal cap is engaged in lawful conduct, so a blanket clause treating any cultivation as criminal activity is unenforceable in Rhode Island. Second, the three-plant-per-unit ceiling gives you a bright line: a grow operation exceeding six total plants, or one drawing commercial-level power and water, is outside the personal-use protection and is fair game for a lease-violation notice. Cultivation also carries real property risk, humidity, mold, electrical load, that you can legitimately address through lease terms even where possession itself is legal.

The key Rhode Island rule: you can ban smoking, but not edibles

Rhode Island codified the landlord line directly. Under R.I. Gen. Laws 21-28.11-29(h), a landlord may not prohibit the consumption of cannabis by non-smoked or non-vaporized means, nor prohibit a tenant from transferring cannabis without compensation. In plain terms, you cannot ban a tenant from eating edibles, using tinctures, or otherwise consuming cannabis without combustion or vapor inside their own unit.

What you can control is smoke and vapor. Rhode Island treats cannabis smoking the same way it treats tobacco: the statute prohibits smoking or vaporizing cannabis in any public place that already bans tobacco smoking, and it separately prohibits cannabis smoking where exposure to the smoke significantly adversely affects the health, safety, or welfare of children (21-28.11-22). A landlord may adopt a smoke-free policy that covers cannabis just as it covers tobacco. The practical result: a well-drafted Rhode Island lease bans smoking and vaping of cannabis, stays silent on or expressly permits non-smoked use, and never tries to prohibit possession outright.

How to write the cannabis clause into a Rhode Island lease

Rhode Island landlord-tenant relationships are governed by the Residential Landlord and Tenant Act (R.I. Gen. Laws ch. 34-18), and any smoking policy you adopt should be clearly disclosed in the written lease. To stay inside 21-28.11-29(h), structure the clause around the method of use, not the substance:

Ban combustion and vapor, not consumption. Prohibit smoking and vaporizing of all substances, including tobacco and cannabis, in the unit and common areas. This is enforceable; a flat ban on cannabis consumption is not.
Address cultivation as a property-condition issue. You may prohibit or limit growing on grounds of moisture, mold, ventilation, and electrical safety, and you can require compliance with the three-mature/three-immature per-unit statutory cap.
Tie enforcement to nuisance and damage. Odor migration into other units, smoke exposure affecting children, and physical damage are the strongest bases for a notice, because they rest on conduct and harm rather than on legal status.
Disclose the policy up front. A smoke-free clause carries more weight when it is signed at move-in rather than introduced mid-tenancy.

Section 8 and public housing: federal law overrides the state rule

The Rhode Island protections in 21-28.11-29(h) do not reach federally assisted housing, because cannabis remains illegal under the federal Controlled Substances Act (21 U.S.C. 801 et seq.). For any unit tied to Section 8 vouchers or public housing, longstanding HUD guidance requires housing authorities to deny admission to current users of a controlled substance, which includes cannabis regardless of Rhode Island legalization. For existing tenants, continued cannabis use is a discretionary basis for lease termination under federal drug-related eviction authority (42 U.S.C. 13661-13662).

This creates a genuine split for Rhode Island landlords who accept vouchers. A tenant lawfully eating an edible under state law may still be violating the federally required lease terms attached to their assistance. If you participate in a HUD program, follow the federal rule and your public housing authority's lease addendum, and do not rely on the state non-smoked-use protection to shield a federally assisted tenancy.

Medical Patient Housing Rules in Rhode Island

Rhode Island protects registered medical cannabis patients in housing.

Under R.I. Gen. Laws § 21-28.11 (Cannabis Act, 2022), 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 Rhode Island, The Federal Trap

HUD PIH 2014-21 mandatory denial applies in Rhode Island. Even though Rhode Island has legalized adult-use cannabis, a Public Housing Authority in Rhode Island 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 Rhode Island, 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 reflects the Rhode Island Cannabis Act (R.I. Gen. Laws ch. 21-28.11), including the rental-specific provision at 21-28.11-29(h) and the personal-use limits at 21-28.11-22, read alongside the Residential Landlord and Tenant Act (ch. 34-18) and federal controlled-substance and assisted-housing rules. It is general information for landlords, not legal advice. Cannabis and housing law interact in ways that turn on specific facts, and federal program requirements can override state protections.

Frequently Asked Questions

Can a Rhode Island landlord ban cannabis smoking in a rental?

Yes. Rhode Island allows landlords to adopt smoke-free policies that cover cannabis, just as they cover tobacco, and the state bars cannabis smoking where it significantly affects the health or safety of children. A ban on smoking and vaporizing is enforceable if it is clearly disclosed in the lease.

Can a landlord ban edibles or tinctures in Rhode Island?

No. Under R.I. Gen. Laws 21-28.11-29(h), a landlord may not prohibit consumption of cannabis by non-smoked or non-vaporized means. A tenant can lawfully use edibles or tinctures inside their unit even if the lease bans smoking.

Can a Rhode Island tenant grow cannabis in a rental?

State law allows up to three mature and three immature plants per dwelling unit for adults 21 and older. A landlord cannot treat lawful personal cultivation as criminal activity, but can restrict growing through lease terms addressing mold, ventilation, and electrical safety, and can act when a grow exceeds the statutory cap.

Do Rhode Island cannabis rules apply to Section 8 or public housing?

No. Because cannabis is still illegal under the federal Controlled Substances Act, HUD guidance requires housing authorities to deny admission to current cannabis users, and continued use is a discretionary basis for termination. The state non-smoked-use protection does not override federal rules for assisted housing.

What is the possession limit for a tenant in Rhode Island?

Adults 21 and older may possess up to 1 ounce on their person and up to 10 ounces in the home per resident, plus lawfully grown live plants, under R.I. Gen. Laws 21-28.11-22.

Should the cannabis policy be in the written lease?

Yes. Rhode Island tenancies are governed by the Residential Landlord and Tenant Act (ch. 34-18), and a smoking policy should be clearly disclosed in writing. A smoke-free clause signed at move-in is far more defensible than one introduced mid-tenancy.
