Adults 21 and older in unincorporated LA County may cultivate up to six living cannabis plants per private residence under California Proposition 64, with plants kept indoors or in a locked, screened outdoor enclosure not visible from a public place under Health and Safety Code Section 11362.1.
California Proposition 64, codified at Health and Safety Code Section 11362.1, lets any adult 21 or older grow up to six plants total per residence regardless of how many adults live there. Outdoor cultivation is allowed only when plants are not visible from a public place and are secured behind a locked enclosure. State law preempts cities and counties from banning indoor personal cultivation outright, though they may impose reasonable health, safety, and electrical rules. LA County enforces nuisance, odor, mold, and electrical safety standards through the Sheriff, Building, and Public Health departments rather than by limiting plant count. Renters need landlord permission. Plants cannot be cultivated where minors can access them and cannot be sold without a state license.
Exceeding six plants is a state infraction or misdemeanor under HSC Section 11358. Plants visible from public places, unlocked outdoor grows, or sales without a state license also trigger county nuisance enforcement under Title 22 abatement.
