Cannabis Regulations


In November 2016, Proposition 64 (the Adult Use of Marijuana Act or “AUMA”) passed in all precincts of Mono County, and the majority of California. Mono County does not have an ordinance allowing for medical or recreational cannabis land-uses such as dispensaries, processing or manufacturing operations, or cultivation in unincorporated Mono County (all lands outside the Town of Mammoth Lakes).

In January 2017 the County extended an adopted moratorium prohibiting cannabis-related business from occurring on all lands until December 2017 while the supervisors develope permantent rules. Since that time, Community Development staff has led community outreach via community meetings to gauge residents’ concerns and desires for regulation.

At this time, staff is awaiting the publication of draft regulations from the State of California in order to identify the roles and programing required by County departments. Staff has been directed by the Board of Supervisors to pursue regulation research in order to maintain local control, rather than creating a County-wide ban or defaulting to State control.

Once an ordinance has been drafted County staff will again attend community meetings for additional public input.
