Home-Grow Cannabis Laws by US State (October 2026)

Can you legally grow cannabis at home where you live, and if so, how many plants? The answer depends entirely on your state, and the differences are bigger than most people expect: some states allow 12 plants per home, some allow two, some require a registration card, and several states where you can legally buy cannabis don’t let you grow a single plant.

We summarized every state’s rules from official sources, mainly state statutes and state cannabis agencies, as of October 2026.

Important: this article is general information, not legal advice. Laws change often, and cities, counties, landlords and homeowners’ associations can add their own rules. Before you plant anything, read the current law for your state using the official links below, and talk to a lawyer if you’re unsure.

A Few Terms First

  1. Per person vs. per residence. Some states set a limit for each adult, plus a cap for the whole household. Others set one limit for the home, no matter how many adults live there.
  2. Mature vs. immature. “Mature” usually means a plant that’s flowering. Many states allow more immature plants than mature ones.
  3. Locked or enclosed space. Most states require plants to be in a space with a lock or other security device, especially to keep out anyone under 21.
  4. Out of public view. Most states require that plants can’t be seen from a public place without binoculars or other optical aids.

The Federal Picture

Under federal law, growing cannabis at home is still illegal. In April 2026, the federal government moved FDA-approved marijuana products and marijuana under state medical marijuana licenses from Schedule I to Schedule III of the Controlled Substances Act. Adult-use (recreational) marijuana remains Schedule I, and a broader rescheduling review was still underway when we wrote this. State laws protect home growers from state penalties only.

That matters most if you live in federally assisted housing. HUD has long held that public housing agencies and owners of federally assisted housing may not allow residents to grow or use marijuana, even where state law allows it.

States Where Only Medical Patients Can Grow

In these states, adult-use home growing is not allowed (or there’s no adult-use law), but registered medical patients can grow a limited number of plants.

State Who can grow and how much Key rules Official source
Hawaii Registered patients: up to 10 plants Grow site registered with the state medical cannabis program Hawaii DOH
Illinois Registered medical patients 21+: up to 5 plants taller than 5 inches per household Enclosed, locked space; not in public view; with the property owner’s consent. Home growing by non-patients is illegal Illinois Cannabis Regulation FAQ
Oklahoma Licensed patients: 6 mature plants + 6 seedlings On property you own or with the owner’s written permission; not visible from the street OMMA
South Dakota Cardholders approved for home cultivation: 2 flowering + 2 non-flowering Must apply for cultivation authorization; enclosed, locked facility SD Department of Health
Washington Medical patients: 4 plants, or 6 if registered (up to 15 with a practitioner’s authorization); max 15 per housing unit Growing by adults who aren’t qualifying patients is a felony WA Liquor and Cannabis Board

Many of the adult-use states above also give medical patients higher limits than the ones shown. If you’re a registered patient, check your state’s medical program rules.

States Where Home Growing Is Not Allowed

Legal to buy, but not to grow:

  1. Delaware. Adult use is legal, but the state says all plant production is restricted to licensed cultivation facilities. (Delaware OMC)
  2. New Jersey. Adult use is legal, but home growing isn’t, including for medical patients. (NJ Cannabis Regulatory Commission)

Medical programs without home growing: Alabama, Arkansas, Florida, Kentucky, Louisiana, Mississippi, Nebraska, New Hampshire, North Dakota, Pennsylvania, Utah and West Virginia have medical cannabis laws that don’t allow patients to grow at home. Patients get cannabis from licensed businesses instead. Several of these states considered home-grow bills recently. New Hampshire’s House passed one in 2025, for example, but the Senate rejected it, so check for changes.

No legal home growing at all: Georgia, Idaho, Indiana, Iowa, Kansas, North Carolina, South Carolina, Tennessee, Texas, Wisconsin and Wyoming. Some of these allow limited low-THC or CBD products, but none allows growing cannabis at home.

Rules That Apply Almost Everywhere

Even in the most permissive states, a few rules show up again and again:

  1. You must be 21 or older (medical programs set their own ages).
  2. You can’t sell what you grow. Gifting small amounts is allowed in some states, but selling homegrown cannabis is illegal everywhere on this list.
  3. No butane or other flammable solvents. Several states, including California, Massachusetts and New York, specifically ban making concentrates at home with volatile solvents.
  4. Local rules can be stricter. Cities and counties can often limit or regulate home grows, especially outdoors.
  5. Your lease matters. Landlord rights vary a lot by state. We cover renters in detail in How to Grow Cannabis in an Apartment, Discreetly.

How We Thought About This for Sunday

Almost every state that allows home growing asks for the same three things: keep plants in an enclosed, locked space, keep them away from anyone under 21, and keep them out of public view. Those rules are also simply good sense in a shared home.

That’s why Sunday is built as an enclosed wooden cabinet with an app-controlled child safety lock. The plant, the nutrients and the pH adjusters all stay behind a locked door that you open from your phone. A carbon filter on the exhaust keeps the smell inside, which helps in states like New York that ask growers to keep odor from bothering the neighbors. And Sunday’s cameras let you check on the plant without opening the door.

Sunday helps you grow responsibly, but it can’t tell you what your state allows. Plant limits, registration cards and distance rules are your responsibility, so check your state’s current law before you start. Sunday hasn’t started shipping yet. Deliveries will begin in the US, and you can join the waitlist for the next batch.

The Takeaway

As of October 2026, adults can grow at home in 20 states plus Washington, D.C., medical patients can grow in a handful more, and the rest don’t allow home growing at all. Limits range from 2 plants per household in Maryland to 12 per home in places like Michigan and Alaska, and the details, from locks to plant tags to registration cards, really matter. Laws change, so treat this as a starting point: follow the official link for your state, read the current rules, and grow within them.
