Medical Cannabis Urgency Ordinance Registration Form

On May 17, 2016, the Mendocino County Board of Supervisors passed an Urgency Ordinance concerning the cultivation of medical cannabis.  Part of that ordinance had a registration requirement for the cultivators of medical cannabis.  Individuals wishing to implement the exemption within the new ordinance and cultivate between 26 and 99 plants per legal parcel are required to contact the Mendocino County Sheriffs Office and fill out an application to cultivate.  For those individuals, that application serves as fulfilling the registration requirement.  Others who wish to cultivate between 1 and 25 medical cannabis plants, may register with the Mendocino County Agricultural Commissioners office.  The ordinance placed a 60 day time limit on the acceptance of registrations, so this registration process will close on July 18, 2016.  Registration in either of these ways entitles the registrant to priority processing for future permit applications. 

Individuals wishing to cultivate between 1 and 25 medical cannabis plants and to register with the Department of Agriculture may do so by filling out the Urgency Ordinance Registration form below.

On June 20, 2016, the Division of Measurement Standards (DMS) released an informational brochure on medical cannabis.  It is intended to provide guidance to cannabis dispensaries, cultivators, distributors, transporters, and product manufacturers in the areas of scale selection, scale registration and testing, service agencies, packaging and labeling inspections, and weighmasters.  Click here to view the brochure.  Click here to go to the DMS webpage.
