San Ramon, CA Cannabis Regulations: Dispensary Zoning (2026)

San Ramon has enacted a comprehensive ban on commercial cannabis activity through its zoning code and municipal code, consistent with its authority under Business and Professions Code 26200 to prohibit licensed cannabis businesses within city limits. Prohibited commercial activities: medical and adult-use retail storefronts (dispensaries), commercial cultivation, manufacturing, distribution (warehousing), and testing laboratories. Only state-licensed delivery by retailers located outside San Ramon is legally accessible to residents, because under Bureau of Cannabis Control v. Santa Cruz County and subsequent litigation California Code of Regulations Title 16 4231 was upheld - state-licensed delivery may cross city lines regardless of local dispensary bans. Medical patients retain the rights under the Compassionate Use Act (Proposition 215, Health & Safety Code 11362.5) and the Medical Marijuana Program Act (Health & Safety Code 11362.7) including possession of up to 8 ounces of dried flower and 6 mature or 12 immature plants for personal medical use, and under the MMP higher amounts with a physician recommendation specifying need. Patients should carry their physician's recommendation or state medical-use ID card. MAUCRSA (Business & Professions Code 26000 et seq.) created the unified licensing regime administered by the Department of Cannabis Control. Personal use and possession are governed by Proposition 64 and Health & Safety Code 11362.1 (see recreational subcategory). Home cultivation for personal medical use is protected to the same extent as adult-use cultivation - cities cannot ban it outright but may require indoor cultivation (San Ramon requires indoor only). Consumption in public places, in vehicles, and within 1,000 feet of schools or youth centers while children are present is prohibited (H&S 11362.3). Employers retain the right to maintain drug-free workplaces under AB 2188 (effective 2024) but cannot discriminate based on off-duty cannabis use detected via non-psychoactive metabolite testing.
