Home Grow Laws in California
Adults 21+ may grow cannabis at home for personal use.
Plant Limits
Overview
California legalized recreational cannabis through Proposition 64 (the Adult Use of Marijuana Act) in 2016. The law permits adults aged 21 and older to grow up to six cannabis plants per household for personal use. California's diverse climate zones, from the sunny Mediterranean coast to the cooler northern forests, offer a wide range of growing conditions that have made the state synonymous with cannabis cultivation for decades.
Home cultivators in California must grow their plants in a locked space that is not visible from a public place. Local jurisdictions have significant authority to regulate home cultivation, and some cities and counties have imposed additional restrictions or outright bans on outdoor growing. Medical patients with a physician's recommendation may also grow for personal medical use, though local rules vary. California does not require home growers to register with the state.
