States Where Home Weed Growing Is Legal 2025
Discover the states where home weed growing is legal in 2025, and everything you need to know to start growing at home.
It depends on your state. No US state allows an open, unsecured backyard cannabis grow with no limits, and cannabis is still a Schedule I controlled substance under federal law. If your state has legalized medical or adult-use cannabis and permits home cultivation, you can grow on your own property within the plant count, security, and location rules that state sets. If your state has not legalized cannabis, or legalized it without a home grow provision, backyard cultivation is illegal.

What Decides Whether Your Grow Is Legal
Three layers of rules apply at once. Federal law makes cannabis illegal nationwide. State law decides whether home cultivation is allowed at all and sets the limits. Local city, county, and property rules decide whether your specific yard qualifies. A grow that satisfies your state can still violate a city ordinance, a lease, or an HOA covenant.

Steps to Confirm Your Backyard Grow Is Legal
- Confirm your state allows home cultivation for medical use, adult use, or both.
- Look up your state's plant limit and write down the exact number of mature and immature plants allowed per household.
- Check your state's rules on where plants may be grown, such as indoors only, or outdoors in a locked area.
- Read your city and county code for cannabis cultivation, fencing, and nuisance rules.
- Read your lease or mortgage terms and your HOA covenants for a cultivation ban.
- Confirm whether your state requires a medical card before you can grow at home.
- Check the security requirement, such as a locked gate, a locked enclosure, or screening from public view.
- Check your state's possession limit for harvested cannabis, since a large grow can exceed it.
Rules That Apply to Most Backyard Grows
- Plant counts are per household or per property, not per person.
- Plants must be screened from public view and from neighbors' sight lines in many states.
- Some states require a locked enclosure or a locked room for outdoor plants.
- Renting usually means you need written permission from the landlord.
- Selling homegrown cannabis remains illegal in every state without a license.
- Giving cannabis away may be capped by weight or by age of the recipient.
States That Do Not Allow Home Grows
Some legal states still ban home cultivation for adult use, including Washington and Illinois. In those states a backyard plant is illegal even though a licensed dispensary can sell you cannabis. Other legal states cap home grows at a small number of plants, commonly six per household, with lower limits for medical patients in some cases.

Federal Risk and Cross-Border Issues
State legalization does not change federal law. Federal charges for a small personal grow are rare, but they remain possible, and federal property, tribal land, and national parks fall outside state cannabis rules. Moving plants or harvested cannabis across state lines is a federal offense even when both states allow cultivation at home.

If Your Grow Is Not Legal
Skip the backyard and buy from a licensed retailer in your state instead. Licensed products are tested for potency and contaminants, and the purchase stays within state law.
