Brentwood prohibits commercial cannabis operations including medical dispensaries under Municipal Code Chapter 17. Patients may possess medical cannabis under Proposition 215 and cultivate limited plants for personal medical use. State-licensed delivery is the only means of obtaining medical cannabis locally.
Proposition 215 (the Compassionate Use Act of 1996, Health and Safety Code section 11362.5) allows qualified patients and primary caregivers to possess and cultivate cannabis for medical use with a physician's recommendation. SB 420 and the Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA, BPC 26000 et seq.) expanded the framework, creating state licensing for medicinal cannabis businesses. However, cities retain broad authority under MAUCRSA to ban or regulate commercial cannabis activity, and Brentwood exercises that authority. Brentwood Municipal Code Chapter 17 and Chapter 5 (depending on specific cannabis sections) prohibit all commercial cannabis operations within city limits, including medical dispensaries, retail storefronts, cultivation, manufacturing, distribution, and testing labs. Cannabis delivery from licensed delivery retailers in other jurisdictions is permitted into Brentwood under state law (14 CCR 40405 and the California Supreme Court's interpretation in the 2021 delivery case), even though Brentwood cannot license a delivery business to be based in the city. Personal medical cultivation is allowed under the limits described in the cannabis home-cultivation bonus subcategory, typically six plants indoors. Patients should carry their physician's recommendation and state medical cannabis card (if issued) when transporting cannabis. Medical patients 18 to 20 are still subject to state-law restrictions barring recreational sales, but may use delivery from medicinal retailers with their physician recommendation.
