In response to California voter approval of Proposition 64 (Adult Use of Marijuana Act) in November 2016, the Contra Costa County Board of Supervisors has directed the County staff to initiate the process of preparing regulations for the establishment of commercial cannabis businesses in the unincorporated areas of the County. The regulations will also address cultivation of cannabis for personal use at home.
In addition to preparation of land use and health regulations for commercial cannabis uses, the Board has also initiated the process of analyzing and preparing a potential taxing program for the various commercial cannabis uses. It is anticipated that no commercial cannabis uses would be authorized until such time as a cannabis tax ballot measure has been approved by County voters. A County cannabis tax initiative could be considered by voters at the next General Election in November 2018, so regulations permitting commercial cannabis uses are not expected to become effective until that time at the earliest.
