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

Chapter II of Division B10 of the San Ramon Municipal Code makes a medical marijuana dispensary a prohibited use or activity throughout the entire city, not just in certain zones. Section B10-2(A) states flatly that no person or entity may operate, locate or otherwise permit a dispensary within city limits, and that no conditional or land use permit, variance, license or other entitlement will be issued to establish one. Subsection (B) closes the leasing loophole: a property owner cannot rent, lease or otherwise permit a dispensary to occupy or use a location, building, structure or vehicle, so a landlord who knowingly leases to a dispensary operator is itself in violation.

The prohibition sits alongside companion bans in the same division: B10-3 bars commercial marijuana cultivation, B10-4 bars marijuana delivery, and B10-5 bars commercial marijuana operations of any type on any premises in the city, all adopted by Ordinance No. 471 in 2017. Only Section B10-6 carves out a narrow exception, allowing an adult twenty-one or older to cultivate up to six living marijuana plants for personal use inside a fully enclosed private residence or accessory structure, subject to fire, electrical and ventilation standards. There is no path in the code for a storefront, delivery hub or cultivation operation to locate anywhere in San Ramon, whether in commercial, industrial or planned-development zoning; the ban is city-wide and use-based rather than tied to a particular zoning map designation.
