Conversion and Co-location Application Process

In accordance with Boulder Revised Code Chapter 6-14, Medical Marijuana Business (MMB) owners who are currently compliant are able to file 100 percent conversions, and co-location applications, whether via physical separation or virtual separation, of both MMB and RMB in their current licensed footprint.

MMBs in mixed use development locations with residential units open as of Oct. 22, 2013 are not eligible for the license conversion or co-location processing.

A person may only hold an ownership percentage interest in up to 3 RMB dispensaries or MMB wellness centers, whether single use or dual use, and there is no limit in the number of licenses which a person may hold an interest in for MIP licenses for MMB/RMB products or Grow locations for either MMB or RMB Greenhouses.

An additional city excise tax of 5 percent was approved by vote for RMB Grow locations and an added city 3.5 percent sales and use tax was approved by vote for RMB dispensary, MIP, and Testing locations. Payment of this city tax will be required for continued RMB license compliance.
