Full Breakdown
Sonoma County Code § 26-88-250 sets zone-by-zone permit tiers for commercial cannabis: a Zoning Permit for smaller cottage-scale uses, a Minor Use Permit for mid-size indoor and mixed-light operations, and a discretionary Use Permit with a noticed Planning Commission hearing for larger cultivation and all storefront/delivery dispensaries. Cultivation is confined to agricultural and resource zones (Table 1A) and limited industrial zones (Table 1C); commercial zones (Table 1B) allow only testing labs and dispensaries, and only in the Neighborhood Commercial, Retail Business and Services, and Limited Commercial districts. Non-medical adult-use commercial cannabis is flatly prohibited unless a use permit is obtained (subsection (c)(1)), and permits run for a limited term, not indefinitely.
Violations & Fines
Operating without the required Zoning, Minor Use, or Use Permit is enforced under Chapter 1; a revoked cannabis permit bars the holder and its owners from any new cannabis permit for two years (§ 26-88-252).
