What States Allow Cannabis Home Growing? (2026 Guide)

Jurisdiction: United States state and District of Columbia home-cultivation laws  |  Last verified: September 4, 2026

Quick answer: Twenty states plus Washington, D.C. allow adults age 21 or older to grow cannabis at home for nonmedical personal use in at least some circumstances. Nevada is included in that total, but its general adult-use permission applies only when the home is more than 25 miles from a state-licensed retail cannabis store. Other states allow home growing only through a medical program, while some states with legal adult-use cannabis still prohibit personal cultivation.

States that allow adult-use cannabis home growing

These 19 states generally authorize at least some adults age 21 or older to cultivate cannabis for personal use under state law:

Alaska, Arizona, California, Colorado, Connecticut, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, New Mexico, New York, Ohio, Oregon, Rhode Island, Vermont and Virginia.

Washington, D.C. also permits adults to cultivate at a principal residence. Each jurisdiction sets its own plant counts, maturity definitions, residence caps, visibility rules, security requirements and housing restrictions.

Nevada allows adult home growing only in limited locations

Nevada is the twentieth state in the adult-use home-grow total, but it is not a blanket statewide permission. The Nevada Cannabis Compliance Board says adults 21 or older may grow at home only when there is no state-licensed retail cannabis store within 25 miles of the home. Plant, household, enclosure, visibility and property-permission rules also apply.

Adult-use states that do not give every adult a home-grow right

• Illinois: adult-use cannabis is legal, but only registered qualifying medical cannabis patients may grow at home. See the Illinois Cannabis Regulation and Tax Act.
• Washington: general adult-use home growing is not allowed. Qualified medical patients or designated providers need valid authorization. See the Washington State Liquor and Cannabis Board guidance.
• Delaware: personal home cultivation remains prohibited, and plant production is restricted to licensed cultivation centers. See the Delaware Office of the Marijuana Commissioner FAQ.
• New Jersey: current law does not authorize private residential cultivation for adult-use or medicinal cannabis. See the New Jersey Cannabis Regulatory Commission FAQ.

Mississippi has a medical-cannabis program, but current rules do not provide patients or caregivers with a personal home-cultivation path.

States with a medical-only home-grow path

These states do not provide a general nonmedical adult home-grow right, but current official programs describe a cultivation path for qualified medical participants:

• Hawaii: registered in-state patients or authorized caregivers may cultivate at a registered grow site. See the Hawaii Medical Cannabis Registry Program.
• Oklahoma: licensed medical patients may cultivate within the program’s plant, property and visibility limits. See the Oklahoma Medical Marijuana Authority guidance.
• South Dakota: medical-cannabis registry applicants may apply to add home cultivation to their card. See the South Dakota Department of Health program FAQ.

Illinois and Washington also belong in the medical-home-grow conversation even though both states separately allow adult-use possession and regulated sales.

Why a simple legal/illegal list is misleading

There are at least four different questions:

1. Does the jurisdiction allow adult-use possession?
2. May an adult cultivate without a medical registration?
3. May a registered patient or caregiver cultivate?
4. Do the residence, lease and local rules allow cultivation at this particular location?

A state can answer “yes” to the first question and “no” to the second. That is why New Jersey, Delaware, Illinois and Washington should not be grouped together without explaining their different medical rules.

Rules to verify before you plant

• Plant count: check whether the limit is per person, household, dwelling, residence or parcel.
• Plant stage: mature, flowering, immature and seedling plants may be counted differently.
• Registration: some states require a medical card, cultivation endorsement or separate personal-cultivation authorization.
• Location: primary-residence, distance, indoor-only, locked-enclosure and public-visibility rules are common.
• Housing: a landlord, lease, housing program or property owner may restrict cultivation even when state law permits it.
• Possession and storage: a state may allow the harvest from legal plants but require excess cannabis to remain secured at home.
• No implied sales right: personal cultivation generally does not authorize selling, bartering or taking cannabis across state lines.

Official national and state sources

The National Conference of State Legislatures reported 24 states and Washington, D.C. with nonmedical adult-use cannabis laws in its June 1, 2026 update. The home-grow classifications above were then checked against official state statutes or agency guidance, because adult-use status alone does not answer the home-cultivation question.
