Full Breakdown
243 of the Mendocino County Zoning Code, adopted by Ordinance No. 4538 on September 10, 2024, governs where cannabis processing, manufacturing, testing, retail/dispensary, distribution, and microbusiness uses may locate. 060's Table 1 sets the permit required by zoning district: retail/dispensary needs only a Zoning Clearance (ZC) in the C2 general commercial, I1 light industrial, I2 general industrial, and PI public/institutional districts, and a Zoning Clearance in C1 for distribution use only, while retail/dispensary is marked "Not Allowed" in RR2, RR5, RR10, R3, RC, SR, AG, UR, RL, FL, and TPZ districts.
Distribution licenses are allowed in any zoning district when operated as an accessory use to another permitted cannabis facility on the same site, and non-storefront retail is likewise allowed in any district as an accessory to a permitted cultivation site. 050(B) sets a 600-foot buffer between most cannabis facilities and any youth-oriented facility, school, park, church, or residential treatment facility existing when the license application is filed; that buffer expands to 1,000 feet for Manufacturing Level 2 (volatile) facilities and microbusinesses with an on-site cultivation site.
090, which requires findings of special circumstances, no material detriment to the public welfare, and consistency with the General Plan. Dispensaries must also occupy a permanent building meeting the California Building Code for commercial or industrial use; the code bars locating any processing, manufacturing, testing, retailing, or distribution activity inside a dwelling unit's habitable rooms or in a required parking space.
Violations & Fines
Operating a retail or dispensary use outside its permitted zoning district, or without the required Zoning Clearance or Administrative Permit, violates Chapter 20.243, and county code declares any violation of the cannabis facilities chapter a public nuisance under Section 6.36.120. An Administrative Permit can be revoked under Section 20.243.110 for non-compliance with its conditions, and the Board of Supervisors may revoke a Cannabis Facility Business License after a public hearing under Section 6.36.130 for acting contrary to applicable law.
