How Many Cannabis Plants Can You Grow in Ohio? (2026 Rules)
Quick answer: Adults 21 and older can grow up to six plants each, with a maximum of 12 at a single residence. You can grow only at your primary residence, in a secured area out of public view. Senate Bill 56, in effect since March 20, 2026, kept those numbers but added new limits on rentals, gifting and over-the-limit growing.
Last verified: October 30, 2026, against Ohio Revised Code §3796.04 and §3796.221. Laws change, so check the official site before you plant.
| Who can grow | Adults 21 and older, at their primary residence |
|---|---|
| Plant limit per adult | 6 plants |
| Household limit | 12 plants at a single residence |
| Mature vs immature | No split. Every homegrown plant counts |
| Where plants can be | In a secured closet, room, greenhouse or other enclosed area, in or on the grounds of your residence, not visible from a public space |
| License or registration | None required in §3796.04 |
| Over-the-limit penalty | Illegal cultivation of marijuana, from a minor misdemeanor to a felony depending on the amount |
How the limit works
Ohio uses two caps, both in R.C. §3796.04(A)(1). Each adult can grow up to six plants, and a single residence can have up to 12.
A home with one adult gets six. Two adults get 12, with no more than six grown by each. Three adults still get 12. A solo grower can’t reach 12 by claiming plants for a friend, because SB 56 bars growing or possessing homegrown marijuana on behalf of another person.
The statute doesn’t count mature and immature plants separately, so count every plant.
SB 56 merged the rules that voters passed as Issue 2 into Chapter 3796. According to the Legislative Service Commission’s final analysis, it kept the six and 12 limits. Older articles that cite R.C. Chapter 3780 are out of date, because that chapter’s home grow law was repealed.
One federal note: home growing remains illegal under federal law even though Ohio allows it. Recreational marijuana is still Schedule I.
Where you can grow
Your grow has to meet all of these rules:
- Primary residence only: A vacation home, a friend’s house or a rented storage unit doesn’t work.
- Secured and enclosed: Use a closet, room, greenhouse or other enclosed area, in the home or on its grounds, that keeps out anyone under 21.
- Out of sight: The grow can’t be visible by normal unaided vision from a public space.
- Not at certain homes: You can’t grow at a type A or type B family child care home, or at a halfway house or similar licensed facility.
You can process your harvest by manual or mechanical means, but hydrocarbon extraction, such as with butane, isn’t allowed.
Renters, landlords and local rules
Renters, this one’s for you. Since SB 56, you can’t grow at a residence occupied under a rental agreement that prohibits growing. A landlord’s ban has to be in the lease (R.C. §3796.24(F)). Going against it isn’t only a lease problem, because a rental ban takes your grow outside the legal protection of §3796.04.
Cities and townships have less power here. Under R.C. §3796.29, they can prohibit or limit licensed cultivators, processors and dispensaries, but they can’t prohibit or limit other activity the chapter authorizes. A local dispensary ban isn’t a home grow ban. The law doesn’t address homeowners associations, so check your HOA rules.
How much of your harvest can you keep?
Read this part twice, because it’s the trap in Ohio’s law. R.C. §3796.221(B) says no person shall knowingly possess more than these cumulative amounts of homegrown and adult-use marijuana:
- 2.5 ounces of plant material, not counting seeds, live plants or clones being grown legally
- 15 grams of extract
The statute has no separate, higher limit for storing cannabis at home. Section 3796.04 does let you store marijuana at your primary residence, but its protection is expressly subject to §3796.221(B). Read plainly, 2.5 ounces is the cap on your combined stash, even at home, and homegrown and dispensary cannabis count together.
That’s a tight limit, since a single harvest could easily exceed it. We found no official state guidance or court ruling on how this applies to a harvest at home, so check the official site or ask an Ohio attorney before you harvest. You can also grow fewer plants.
Can you give it away?
Yes, but SB 56 made the rules stricter. Under R.C. §3796.221(A)(4), you can transfer homegrown or adult-use marijuana to another adult 21 or older only if all of these apply:
- There’s no payment of any kind
- You give the same person no more than 2.5 ounces of plant material or 15 grams of extract in one day
- The transfer happens on privately owned property used primarily for residential or agricultural purposes
Any other transfer can be charged as trafficking in marijuana. Giving marijuana to anyone under 21 is a first-degree misdemeanor, and a fifth-degree felony after a prior conviction. Selling homegrown is never allowed.
Where do you get seeds or clones?
R.C. §3796.06(B) lists seeds, live plants and clones among the forms of adult-use marijuana that may be dispensed. We couldn’t confirm which stores stock them, so call a licensed dispensary first.
What if you go over the limit?
Knowingly exceeding the limit by any number of plants now counts as illegal cultivation of marijuana (R.C. §§3796.04(C), 3796.99(E)). Penalties under R.C. §2925.04(C)(5) depend on the amount of marijuana involved, not the plant count:
- Under 100 grams: minor misdemeanor
- 100 to under 200 grams: fourth-degree misdemeanor
- 200 to under 1,000 grams: fifth-degree felony
- 1,000 to under 5,000 grams: third-degree felony
- 5,000 grams or more: third-degree felony with a presumption of prison, then second-degree at 20,000 grams
Penalties generally go up if the offense happens near a school or a juvenile. Possessing more than 2.5 ounces is charged separately as possession of marijuana, under the tiers in R.C. §2925.11(C)(3).
Ohio home grow FAQ
Can one adult grow 12 plants in Ohio?
No. Each Ohio adult can grow up to six plants. It takes at least two adults at the same primary residence to reach the 12-plant maximum, and you can’t grow on behalf of someone else.
Can a landlord ban home growing in Ohio?
Yes. Since SB 56 took effect on March 20, 2026, Ohio doesn’t allow home growing at a rental if the rental agreement prohibits it. Check your lease before you plant.
Can you keep more than 2.5 ounces of homegrown at home in Ohio?
Not clearly. Ohio’s statute limits possession to a combined 2.5 ounces of plant material and 15 grams of extract, with no separate at-home limit. We found no official guidance on harvests, so check before you plant.
Did SB 56 change Ohio’s plant limits?
No. SB 56 kept the limits of six plants per adult and 12 per residence. It did add rental and child care home restrictions, tighter gifting rules, and illegal cultivation charges for exceeding the limit by any number of plants.
