Rancho Cucamonga, CA Cannabis Regulations: Dispensary Zoning (2026)

Rancho Cucamonga has adopted a comprehensive local prohibition on commercial cannabis activity under Municipal Code Chapter 8.52 and corresponding Development Code provisions, meaning no retail dispensaries, cultivation sites, manufacturing facilities, testing laboratories, microbusinesses, or distribution operations may be established within the city limits regardless of state licensing under MAUCRSA (the Medicinal and Adult-Use Cannabis Regulation and Safety Act). The City relies on its general zoning authority under California Business and Professions Code Section 26200, which preserves local authority to prohibit commercial cannabis businesses. Delivery by state-licensed operators based in other California jurisdictions is not prohibited because of the state Bureau of Cannabis Control regulation 5416(d) that guarantees statewide delivery access. Attempts to open an unlicensed retail storefront or grow operation in Rancho Cucamonga are subject to both municipal code enforcement (including administrative fines, criminal misdemeanor charges, and public nuisance abatement) and state enforcement through the Department of Cannabis Control. Voters or the City Council would need to amend the Municipal Code to allow any local retail operation, and there is no current sunset date.
