The City of Boulder elected to require separate licenses for both the OPC (grow operation) and retail operations of a MMC.
Be warned that it is not enough to submit a MMC business license application for the retail side of the business. Also, if you added the grow after June 18, you are required to submit the application for the grow by 8/31/10.
Of course, if you had both the grow and retail in operation before June 18, you may submit both applications on or before 10/31/10. Please be advised that it appears that priority for location (i.e., within 500 ft. of three other MMCs) will be allotted based on date of submission of the application, not date of operation. This is not final, but you should get your application in a.s.a.p.
