In Arizona, adults 21 and over may legally cultivate up to 6 marijuana plants per adult (12 per household) for personal use under Proposition 207 and A.R.S. 36-2852. Cultivation above that limit is a felony under A.R.S. 13-3405(A)(3): Class 6 for under 2 pounds of finished product, Class 5 for 2-4 pounds, Class 4 for over 4 pounds. Possession-for-sale at any amount is a Class 2 felony. Call (480) 582-3637 for help from a criminal defense lawyer.
Legal Home Cultivation Under Prop 207
Arizona changed direction on marijuana cultivation in November 2020 when voters passed Proposition 207 (Proposition 207). Six years later, most Kingman-area defendants still don’t know exactly what changed and what didn’t. Personal cultivation is now legal within specific limits. Everything beyond those limits stayed criminal.
The statute that codifies personal cultivation is A.R.S. 36-2852(A)(3). It allows adults 21 and over to possess, cultivate, and harvest up to 6 marijuana plants per adult, capped at 12 plants per residence regardless of how many adults live there. Plants must be cultivated within a single enclosed area equipped with a lock, on the property where the adult resides, and not visible from any public view. Miss any of those conditions and the “legal” personal cultivation becomes illegal.
The Arizona Department of Health Services regulates commercial marijuana licensing but does not regulate personal home cultivation. Personal cultivation requires no state license or paperwork. The home grower may keep all marijuana produced from their legal plants — no possession limit on the flower stored at home from personal cultivation. Up to 1 ounce of finished marijuana may be possessed OUTSIDE the residence; anything above that limit outside the home is a separate possession offense.
The NIDA marijuana research provides clinical context on marijuana use. Arizona’s adoption of recreational cultivation followed similar reforms in Colorado (2012), Washington (2012), and California (2016). The Class 6 felony floor for over-limit cultivation remains substantially less severe than the pre-Prop 207 Class 4 felony for ANY cultivation.
When Cultivation Becomes a Crime
Cultivation of marijuana remains a crime under A.R.S. 13-3405(A)(3) in five scenarios:
- Plant count exceeds 6 per adult (or 12 per household)
- The cultivator is under 21 years old
- Plants are visible from a public area — street, sidewalk, neighbor’s window
- Plants are cultivated outside a locked enclosed area
- Cultivation is commercial scale and unlicensed (intent to sell beyond personal use)
Plant count is measured at the time of police observation. Seedlings count exactly the same as mature flowering plants. Hydroponic and outdoor cultivation are treated identically. The Arizona Department of Public Safety has reduced cultivation-only enforcement significantly since Prop 207, but Mohave, Pinal, and Maricopa counties continue active prosecution of over-limit grows — particularly those with suspected commercial ties.
Medical marijuana cardholders under the Arizona Medical Marijuana Act (Arizona Department of Health Services) retain higher personal cultivation rights: 12 plants per qualifying patient with proper registration. The medical limits apply only to actively-registered cardholders. Prop 207 recreational limits apply to everyone else. A patient whose card lapses drops back to the 6-plant recreational limit immediately.
Penalty Range by Plant Count and Weight
Penalty scales by the WEIGHT of finished or in-progress marijuana under A.R.S. 13-3405(A)(3), not just plant count. Plant count triggers the charge; weight determines the class:
| Quantity | Classification | Penalty Range |
|---|---|---|
| Under 2 pounds finished | Class 6 felony | 4 months to 2 years prison |
| 2 to 4 pounds | Class 5 felony | 6 months to 2.5 years prison |
| Over 4 pounds | Class 4 felony | 1 to 3.75 years prison |
| Possession for sale (any quantity) | Class 2 felony | 3 to 12.5 years prison |
First-time Class 6 marijuana cultivation cases often qualify for designation as a misdemeanor at sentencing under A.R.S. 13-604. Designation avoids the felony record and restores firearm rights. The Arizona Department of Corrections reports first-time cultivation convictions averaged 1.2 years actual time served in 2023, with most receiving probation rather than prison. Fines reach $150,000 per offense. Sale-intent indicators (drying racks, packaging materials, scales, ledgers, large finished quantities) drive the Class 2 upgrade — this is where personal cultivation crosses into commercial territory prosecutors will pursue.
Commercial Cultivation Without License
Commercial-scale cultivation requires an Arizona Department of Health Services marijuana establishment license under A.R.S. 36-2852. Arizona Department of Health Services issues a limited number of licenses with rigorous facility, security, and regulatory compliance requirements. Black-market commercial cultivation operating outside the licensed system remains a Class 2 felony when sale intent is proven, regardless of recreational legalization.
The indicators of commercial scale are recognizable: grow rooms exceeding 6-12 plants, professional lighting and ventilation systems, drying racks, vacuum sealers, digital scales, ledgers or pay-and-owe sheets, multiple delivery vehicles, and large quantities of finished product ready for distribution. Mohave County and Pinal County prosecutors have aggressively pursued unlicensed commercial cultivation, particularly on rural properties used as distribution-hub grow houses.
The State Bar of Arizona maintains case law summaries on the post-Prop 207 prosecution landscape. Defense theory in commercial cultivation cases focuses on attacking the sale-intent element specifically. Without the sale indicators, over-limit personal cultivation can defend as Class 6 rather than Class 2 — a difference of 3 years prison exposure vs 2 years probation-eligible. A skilled criminal defense lawyer coordinates the criminal defense with the asset forfeiture defense, since rural grow properties are frequent forfeiture targets under A.R.S. 13-4301.
Federal Marijuana Cultivation Exposure
Marijuana remains a Schedule I controlled substance under federal law as of 2026, despite state-level legalization in 24 states. The DEA drug schedules confirms marijuana’s Schedule I status pending any future federal rescheduling. Federal cultivation prosecutions under 21 U.S.C. 841 continue at a low but nonzero rate.
The federal mandatory minimum sentence is 5 years for cultivation of 100 or more marijuana plants and 10 years for 1,000 or more plants. Federal enforcement of personal-use cultivation within state-legal limits is rare. Federal Department of Justice guidance (the Cole Memorandum, rescinded 2018, partially restored by Garland Memorandum 2021) generally defers to state regulatory frameworks for personal-use and state-licensed commercial activity. Black market commercial cultivation crossing state lines remains a federal enforcement priority.
The U.S. Sentencing Commission tracks federal marijuana sentencing annually. Trespass cultivation on Bureau of Land Management or Forest Service land in northern Arizona is prosecuted federally without regard to state law — this affects some remote Mohave and Coconino County properties. National Park cultivation is federal without exception.

Possibly. Civil forfeiture under A.R.S. 13-4301 reaches real property used in significant drug operations. Forfeiture is more common in commercial-scale cultivation than in over-limit personal cultivation. The owner must file a written demand for hearing within 30 days of notice or lose the property by default.
Federal prosecution of personal-use cultivation within state-legal limits is rare. Federal DOJ guidance generally defers to state regulatory frameworks. Federal enforcement focuses on commercial cultivation at 100 or more plants (5 year mandatory minimum) or 1,000 or more plants (10 year mandatory minimum) under 21 U.S.C. 841.
