Arizona home-grow rules in plain language

• Minimum age: 21.
• Per-person limit: six plants.
• Residence limit: 12 plants total when two or more qualifying adults live there.
• Location: the adult’s primary residence.
• Enclosure: a closet, room, greenhouse or other enclosed area on the residence grounds.
• Security: the enclosure needs a lock or other security device that prevents access by minors.
• Public view: plants cannot be visible from public view without binoculars, aircraft or other optical aids.
• Processing: personal use may include manual or mechanical processing such as sieving or ice-water separation, but not chemical extraction or synthesis.

How the plant limits work

One qualifying adult may grow up to six plants. Two or more qualifying adults at the same primary residence may cultivate up to 12 plants total. Additional adults do not raise the residence limit beyond 12.

Arizona’s adult-use statute does not split the six plants into mature and immature categories. Count every cannabis plant in the personal grow toward the total.

What qualifies as an enclosed grow area?

The statute lists a closet, room, greenhouse or another enclosed area on the grounds of the residence. Whatever structure is used must have a lock or other security device that prevents access by minors and must keep the plants outside public view.

Personal cultivation is not chemical extraction

Arizona permits processing the homegrown cannabis by manual or mechanical means, including sieving and ice-water separation. It excludes chemical extraction and chemical synthesis from this personal-cultivation protection. Do not treat a six-plant grow as authorization for a hazardous extraction setup.

Before you start

1. Confirm the primary residence. Do not use a separate unlicensed commercial space.
2. Count the entire residence. Keep the total at six for one qualifying adult or 12 for two or more.
3. Finish the enclosure. Install a lock or security device before bringing in plants.
4. Check public sight lines. Confirm that the plants cannot be seen from a public location.
5. Keep processing nonchemical. Avoid chemical extraction or synthesis.
