Who Can Grow
Any adult 21 or older may grow cannabis at home in Oregon for personal use. No registration, permit, or medical card is required. Oregon has permitted home cultivation since July 1, 2015, following voters passing Measure 91 in November 2014 – making Oregon one of the earliest states to legalize adult-use cannabis and home cultivation.
There is no residency requirement to use cannabis in Oregon, but home cultivation is tied to a household address and is for personal, noncommercial use only.
How Many Plants
Oregon law sets a flat limit of four plants per household under ORS 475C.305. That limit is a household cap – it does not increase based on the number of adults living at the address. One adult or four adults at the same household: four plants total.
Oregon does not distinguish between mature and immature plants for the recreational home grow limit. All plants at all stages count toward the four-plant household cap. There is no separate seedling category with a higher allowance, as there is in states like Maine and New Mexico.
Where You Can Grow
Both indoor and outdoor cultivation are permitted under Oregon law. The key requirement is that plants must not be visible from a public place. That applies to outdoor grows visible from streets, sidewalks, or neighboring properties, and to indoor grows where plants might be seen through windows.
Oregon defines “household” to include not just the inside of the home but any place in or around the housing unit where the occupants are producing, processing, or storing homegrown plants. That means the yard and curtilage of the property are included in the household grow area.
There is no requirement in the state statute that plants be kept in a locked space – a distinction from most other legal states. However, local ordinances may impose additional requirements, including requiring indoor-only grows (see Local Ordinances below).
Security Requirements
The state statute does not require that home grows be kept in a locked, enclosed space. The main requirement is that plants not be visible from a public place. Keeping plants out of sight is the core obligation under ORS 475C.305.
That said, good practice is to keep your grow inaccessible to children and to visitors who are not authorized. Some local jurisdictions may impose their own security or enclosure requirements beyond what state law requires.
Local Ordinances
Oregon cities and counties have the authority to regulate the time, place, and manner of home cannabis cultivation, including requiring that grows be conducted indoors. A court case – Brown v. City of Grants Pass – confirmed that municipalities can require indoor-only cultivation without violating state preemption, as long as they do not ban home growing entirely.
Some Oregon cities have used this authority to require that home grows be conducted indoors or in enclosed spaces. Before setting up an outdoor grow, check your local city or county ordinances to confirm what is permitted in your jurisdiction.
Local governments in Oregon cannot ban home cultivation outright or restrict commercial cannabis sales in a way that affects the personal cultivation right.
Home Processing Rules
Oregon’s home processing rules are notably more detailed than most states. Under ORS 475C.305, a household may:
- Make and store homemade cannabinoid products (edibles, topicals, etc.) with no stated plant-based limit
- Possess up to 16 ounces of homemade cannabinoid concentrates at the household at any time
- Possess up to 72 ounces of liquid cannabinoid products at the household at any time
Importantly, cannabinoid extracts – concentrated cannabis oil – must be purchased from a licensed retailer. Home extraction to produce extract or oil is not permitted under the personal use statute. The statute exempts homemade concentrates (things like dry sift, rosin, and hash made without volatile solvents) but treats purchased extracts separately.
Making extracts at home without a license is treated as unlawful manufacture under Oregon law.
Renters and Landlords
Oregon landlords have the right to prohibit cannabis cultivation in rental properties. Under ORS 90.396, landlords can issue termination notices for lease violations that include cultivation. Renters should review their lease agreement and get written permission from their landlord before starting a grow.
Additionally, if you live in federally subsidized housing, cannabis cultivation remains prohibited regardless of state law.
Medical Patient Limits
Oregon Medical Marijuana Program (OMMP) cardholders are permitted to grow significantly more than recreational adults. Under ORS 475C.806, registered patients may grow:
- Up to 6 mature (flowering) plants per patient, with a maximum of 12 mature plants at one address
- Up to 12 immature plants that are 24 inches tall or taller, per patient, up to 24 at one address
- Unlimited plants under 24 inches tall
Medical patients who cannot grow for themselves may designate a registered grower. Grow sites with registered medical patients operate under different rules than recreational household grows and are subject to reporting and registration requirements through the Oregon Health Authority.
If a recreational adult and a medical patient share the same address, the address is generally subject to the medical rules, with the household capped at 12 total mature plants.
Outdoor Growing in Oregon
Oregon’s outdoor growing conditions are among the best of any state in the series. The Willamette Valley – where most of the state’s population lives – sits in USDA hardiness zones 8a and 8b, with long, warm summers and mild fall weather that gives photoperiod strains ample time to finish. Southern Oregon around Medford and the Rogue Valley can be even warmer and drier, with a longer season.
Eastern Oregon and higher elevation areas are considerably different – zones 4 to 6 in the mountains and high desert, with much shorter growing windows and earlier frosts.
For most of western Oregon, the outdoor season runs from May through October. The late-summer pattern matters: Oregon’s famously wet winters and springs give way to dry summers, but early October often brings the first significant rain. Harvesting before mid-October reduces the risk of mold and bud rot in wetter years.
Oregon’s climate is well-suited to photoperiod outdoor grows. A plant started indoors in March or April and moved outside after the last frost can reach full maturity by late September in the Willamette Valley. Growers in wetter coastal areas should prioritize mold-resistant genetics.
Penalties for Going Over the Limit
Oregon’s penalty structure for excess home cultivation under ORS 475C.349 scales by how far over the four-plant limit a grower is:
- 4 plants (legal): no penalty
- 5 to 8 plants: Class B misdemeanor, up to 6 months in jail and a fine up to $2,500
- 9 to 15 plants: Class A misdemeanor, up to 1 year in jail and a fine up to $6,250
- 16 or more plants: Class C felony, up to 5 years in prison and a fine up to $125,000
Growing within 1,000 feet of a school grounds elevates the offense to a Class A felony with up to 20 years in prison and a fine up to $375,000 – even for home growers exceeding the limit.
Ready to Start Growing?
Oregon’s four-plant household limit is on the lower end among legal states, but the state’s outdoor climate – particularly in western Oregon – makes those four plants exceptionally productive. A well-grown outdoor plant in the Willamette Valley or Rogue Valley can yield a substantial personal harvest. The lack of a locked space requirement and the absence of registration make Oregon one of the simpler states in terms of compliance overhead.
