Full Breakdown

California Health and Safety Code Section 11362.2 grants adults twenty-one and older the right to cultivate up to six cannabis plants per residence for personal use. Cities cannot ban indoor personal cultivation but may impose reasonable regulations and may prohibit outdoor cultivation entirely. Thousand Oaks requires personal cultivation occur indoors within a fully enclosed, secure structure, not visible from public rights-of-way, with adequate ventilation to prevent odor nuisance to neighbors. Outdoor cultivation is prohibited. The six-plant cap applies per residence regardless of how many adults live there. Sale of any home-grown cannabis remains illegal without state commercial licenses.

Violations & Fines

Exceeding six plants or growing outdoors triggers infractions starting around two hundred fifty dollars. Sale of home-grown cannabis is a misdemeanor under state law with possible jail time.

Frequently Asked Questions

Can my Thousand Oaks roommates and I each grow six plants?
No. The six-plant cap is per residence, not per adult. A household of four adults still grows a combined maximum of six plants under state and local law.
Do I need a permit to grow indoors?
Not for the cultivation itself, but any structural work, electrical changes, or new construction for grow spaces requires standard building permits through Thousand Oaks Community Development.
