Why San Mateo Has Some of the Strictest Cannabis Regulations in the State

If you live in San Mateo or are thinking about moving there, cannabis regulations are one of those things you probably won't think about until they affect you directly. San Mateo has 2 specific rules on the books covering different aspects of cannabis regulations, and some of them might surprise you.

Dispensary Zoning

San Mateo prohibits all cannabis dispensaries and commercial cannabis operations within city limits under Chapter 7.45 (Ordinance 2017-4). No storefront, mobile, or delivery cannabis businesses are permitted. The city exercised its local opt-out authority under CA Business and Professions Code Section 26200.

Key details: Dispensaries: Banned — Ord. 2017-4 / Ch. 7.45. Delivery: Banned. Manufacturing: Banned. State Authority: CA B&P Code §26200 opt-out. Nearest Sales: Outside city limits.

Operating any commercial cannabis business in San Mateo is a violation of Chapter 7.45. Enforcement includes code enforcement action, business closure, and potential criminal prosecution.

Compared to other cities, San Mateo takes a harder line on dispensary zoning. The enforcement and penalty structure reflects that.

Home Cultivation

San Mateo adopted Ordinance 2017-4 adding Chapter 7.45 to prohibit outdoor cannabis cultivation within city limits. Indoor cultivation of up to six plants per residence is protected under Proposition 64 (CA H&S Code Section 11362.2). Plants must be in a locked space not visible from public areas.

Key details: Outdoor Growing: Prohibited — Ord. 2017-4 / Ch. 7.45. Indoor Growing: Up to 6 plants (Prop 64). Requirements: Locked space, not visible. City Code: SMMC §7.46.110. Landlord Rules: May prohibit in lease.

Outdoor cultivation violates SMMC Chapter 7.45. Cultivating more than six plants without a license is a state misdemeanor. Indoor cultivation not meeting visibility and security requirements may be cited under both city and state law.

Compared to other cities, San Mateo takes a harder line on home cultivation. The enforcement and penalty structure reflects that.
