Summary

Unincorporated Mendocino County has not opted out of cannabis retail: Section 20.243.060 allows retail and dispensary uses with a Zoning Clearance in the C2, I1, I2, and PI districts, while every rural-residential, single-family, and suburban district shows "Not Allowed" on the permit table. Dispensaries also cannot sit within 600 feet of a school, park, church, or youth facility under Section 20.243.050(B).

These county ordinances apply to unincorporated areas of Mendocino County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

All cannabis facilities shall be permitted in accordance with this Section. All new cannabis facilities shall obtain approval from other State and Local agencies with permitting jurisdiction. Cannabis facilities may be allowed with an approved Zoning Clearance or Administrative Permit as required for the zoning district in which the cannabis facility is located as listed in Table 1, below... — = Not Allowed; ZC = Zoning Clearance; AP = Administrative Permit. Notwithstanding the above Table 1:(A)Distribution licenses shall be allowed in any zoning district as an accessory use to other cannabis facilities on the site, subject to the limitations of paragraph (E) of section 20.243.040.(B)Non-Storefront Retail locations shall be permitted in any zoning district as an accessory use to a cultivation site under application review or permitted pursuant to Chapters 10A.17 and 20.242.

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.

Frequently Asked Questions

Has Mendocino County opted out of allowing cannabis dispensaries?
No. The county allows retail and dispensary cannabis facilities with a Zoning Clearance in the C2, I1, I2, and PI zoning districts under Section 20.243.060's Table 1; it has not adopted a countywide retail ban.
Where in unincorporated Mendocino County can a cannabis dispensary open?
Only in commercial and industrial districts, specifically C2, I1, I2, and PI, where Section 20.243.060 requires a Zoning Clearance. The permit table marks retail/dispensary "Not Allowed" in every rural-residential, single-family, agricultural, and timber-production district.
How far must a dispensary be from a school or park?
Section 20.243.050(B) requires 600 feet from any school, park, church, youth facility, or residential treatment facility in existence when the license is applied for, measured in a straight line to the nearest point where users are typically present.
Can that 600-foot buffer ever be reduced?
Yes. An applicant can seek a reduction through an Administrative Permit under Section 20.243.090, which requires findings of special circumstances, no material detriment to the surrounding property, and consistency with the General Plan before the Zoning Administrator can approve it.
