A commissary is a facility approved by the health department as a base of operations for a mobile food establishment where food, containers, and supplies are kept, handled, prepared, packaged or stored, and where fresh water is replaced, and waste water is disposed of. Most commissaries are licensed fixed restaurants used by agreement between management of the restaurant and the mobile food operator. A Commissary Agreement must be completed and submitted for licensing. The Colorado Co-Pack Directory maintains a list of approved kitchens whose sole purpose is to rent time to the public.
