Landlord ban authority, possession and home-grow limits, medical patient housing rules, and federal Section 8 restrictions in Delaware.
Delaware is one of the few states that writes a tenant's cannabis rights directly into statute. Since HB 1 took effect (signed April 2023), adults 21 and older may possess up to 1 ounce of marijuana flower, along with limited concentrate and product amounts, under the Delaware Marijuana Control Act (Title 4, Chapter 13). But the provision that matters most to landlords is Title 4 § 1307, which sharply limits your authority to prohibit marijuana in a residential rental.
The short version: you can ban smoking the same way you ban tobacco, but in most rentals you cannot ban a tenant's mere possession or non-smoked consumption (edibles, tinctures) unless a narrow exception applies. Home cultivation stays illegal for everyone, and federally assisted housing follows a different rulebook. Here is how to write a lease that holds up.
Delaware is classified as Adult-Use Recreational Legal (effective 2023). The governing statute is 7 Del. C. § 1301 et seq. (HB 1 / HB 2, 2023).
No home cultivation permitted under Delaware law. Landlord may ban smoking. Medical patients protected from non-federally-funded housing discrimination under 16 Del. C. § 4905A.
Recreational marijuana is legal in Delaware for adults 21 and older, who may possess up to 1 ounce of flower, 12 grams of concentrate, or products containing 750 mg or less of delta-9 THC. Medical marijuana has been legal since 2011 under Title 16, Chapter 49A. The licensed adult-use retail market is overseen by the Delaware Office of the Marijuana Commissioner.
Two limits directly affect rental properties. First, home cultivation remains prohibited for personal and recreational users; growing without a license under Chapter 49A is still a criminal offense under Title 16 § 4764. A tenant running a grow operation in your unit is breaking state law, full stop. Second, public consumption is unlawful — using marijuana in an area accessible to the public is prohibited, which reaches shared hallways, lobbies, and common areas of a multifamily building.
Title 4 § 1307 is the controlling statute. In a residential rental, a landlord may prohibit the possession or the non-smoked consumption of marijuana only when one of three exceptions applies. Outside those exceptions, a blanket lease clause banning a tenant from possessing marijuana or eating an edible is unenforceable in Delaware.
What you keep is control over smoking. Section 1307 protects possession and non-smoked use; it does not force you to allow smoke. You can prohibit smoking marijuana on the premises exactly as you would prohibit smoking tobacco — through a standard no-smoking clause. That distinction is the practical center of every Delaware cannabis lease: smoke is bannable, possession and edibles generally are not.
Under § 1307, a Delaware landlord may prohibit possession or non-smoked consumption only if one of these applies:
If none of these fit your property, drafting a possession ban into the lease will not survive a challenge. Focus your clause on smoking and on the conduct you can always police — damage, odor nuisance, illegal cultivation, and public-area use.
Marijuana is still a Schedule I controlled substance under the federal Controlled Substances Act, and that federal illegality controls federally subsidized housing regardless of Delaware law. Public housing authorities are required by federal rules to deny admission to households where a member uses marijuana, and to have authority to evict for drug-related activity. State legalization does not override those obligations.
Delaware's statute anticipates this. The third § 1307 exception — the federal-law conflict — is precisely what lets an owner of Section 8 or public housing enforce the federally mandated ban without violating Delaware's tenant-protection rule. If your property carries a HUD contract, a housing-assistance payment, or another federal benefit, you are on the exception side of § 1307 and can prohibit possession and use. Document the federal program in the lease so the basis for the ban is on the record.
For a standard, non-exempt Delaware rental, build the lease around what the statute actually permits:
Where an exception applies — owner-occupied 3-room building, institutional housing, or a federally assisted property — you may go further and prohibit possession and non-smoked use, but state the qualifying basis clearly.
Under 7 Del. C. § 1301 et seq. (HB 1 / HB 2, 2023), 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 Delaware, 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 the Delaware Marijuana Control Act (Title 4, Chapter 13), the landlord-rental provision at Title 4 § 1307, possession and cultivation rules under Title 16 § 4764, and the federal treatment of marijuana in assisted housing, as of 2026. It is general information for Delaware landlords, not legal advice. Cannabis law changes quickly and application depends on your building type and any federal housing program involved; confirm the current statute and consult a Delaware landlord-tenant attorney before drafting or enforcing a cannabis clause.
Only partly. Under Title 4 § 1307 you can prohibit smoking marijuana on the premises, just like tobacco. But in a standard rental you cannot ban a tenant's mere possession or non-smoked consumption (edibles, tinctures) unless one of three exceptions applies: an owner-occupied building with 3 or fewer rented rooms and 3 or fewer tenants, institutional/service housing, or a property where a ban is required to comply with federal law.
Yes. Section 1307 protects possession and non-smoked use, not smoking. A no-smoking clause that covers tobacco and marijuana smoke is enforceable in Delaware rentals, including in buildings that don't qualify for any exception.
No. Home cultivation of marijuana remains illegal for personal and recreational users in Delaware; growing without a license is a criminal offense under Title 16 § 4764. A lease clause barring cultivation or manufacturing on the premises is enforceable, and a tenant growing marijuana is violating state law regardless of the lease.
Adults 21 and older may possess up to 1 ounce of marijuana flower, 12 grams of concentrate, or cannabis products containing 750 mg or less of delta-9 THC. Because § 1307 protects possession in most rentals, you generally cannot treat lawful possession within these limits as a lease violation.
Federally assisted housing follows federal law, under which marijuana is still a Schedule I controlled substance. PHAs must deny admission to households with a marijuana-using member and can enforce drug-related eviction authority. Delaware's third § 1307 exception — the federal-law conflict — lets owners of these properties enforce that ban without violating state law. Cite the federal program in the lease.
Yes, on grounds independent of the cannabis rules. Odor that creates a nuisance for other tenants, smoke migration in a no-smoking building, and property damage are enforceable through ordinary lease terms and the Delaware Residential Landlord-Tenant Code (Title 25, Chapter 51). Base the action on the nuisance, smoking-clause breach, or damage — not on lawful possession.
Federal authority: 21 U.S.C. § 812; HUD PIH 2014-21. State authority: 7 Del. C. § 1301 et seq. (HB 1 / HB 2, 2023). 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 Delaware attorney before making a lease, screening, or eviction decision involving cannabis.
