1.141-9 (b) Unrelated use --

(1) In general.

Whether a private business use is related to a government use financed with the proceeds of an issue is determined on a case-by-case basis, emphasizing the operational relationship between the government use and the private business use. In general, a facility that is used for a related private business use must be located within, or adjacent to, the governmentally used facility.

(2) Use for the same purpose as government use.

Use of a facility by a nongovernmental person for the same purpose as use by a governmental person is not treated as unrelated use if the government use is not insignificant. Similarly, a use of a facility in the same manner both for private business use that is related use and private business use that is unrelated use does not result in unrelated use if the related use is not insignificant. For example, a privately owned pharmacy in a governmentally owned hospital does not ordinarily result in unrelated use solely because the pharmacy also serves individuals not using the hospital. In addition, use of parking spaces in a garage by a nongovernmental person is not treated as unrelated use if more than an insignificant portion of the parking spaces are used for a government use (or a private business use that is related to a government use), even though the use by the nongovernmental person is not directly related to that other use.
