Tennessee Code Title 71. Welfare § 71-4-503

(a) Whenever any new buildings or other facilities are to be constructed by the state or on any other public property or when any existing contracts expire or are changed in any way, the department shall be notified and it shall promptly make an investigation and survey of the public property to determine if, in its judgment, the location is suitable for one (1) or more vending facilities. If, in the department's judgment, the location is suitable for a vending facility, the department may exercise its priority to establish such a vending facility.

(b) If the department exercises the priority under this part, it shall have the right to establish such a vending facility, and it shall provide the necessary alterations, plumbing and electrical services, the necessary equipment, merchandise, a licensed or temporary manager, and the appropriate supervision of the manager. The public property management shall cooperate with the department in whatever manner necessary in order for it to carry out this part. The space for the vending facilities and utilities shall be provided at no cost; provided, that the cost of telephone service shall not be the responsibility of the public property management. In cafeteria operations, the licensed or temporary manager may be required to pay a percentage of sales to the public property management in accordance with agreements negotiated between the department and the public property management.
