(a) General rule.
(1) Under section 103(c)(5), interest paid on an issue of obligations issued by a State or local governmental unit (as defined in §1.103-1) is not includable in gross income if substantially all of the proceeds of such issue is to be used to finance the acquisition or development of land as the site for an industrial park (referred to in this section as “industrial park bonds”). However, interest on an obligation of such an issue is includable in gross income if the obligation is held by a substantial user or a related person (as described in section 103(c)(7) and §1.103-11). If substantially all of the proceeds of a bond issue is to be so used to finance an industrial park, the debt obligations are treated as obligations described in section 103(a)(1) and §1.103-1 even though such obligations are industrial development bonds within the meaning of section 103(c)(2) and §1.103-7. Whether substantially all of the proceeds of an issue of governmental obligations are used to finance an industrial park is determined consistently with the rules for exempt facilities in §1.103-8(a)(1)(i).
(2) The provisions of subparagraph (1) of this paragraph shall also apply to an issue of obligations substantially all of the proceeds of which is to be used to acquire or develop land as the site for an industrial park described in section 103(c)(5) and this section and for either or both of the following purposes: (i) To finance exempt facilities described in section 103(c)(4) and §1.103-8, (ii) to finance facilities to be used by an exempt person.
(3) Section 103(c)(5) only becomes applicable where the bond issue meets both the trade or business and the security interest tests so that the obligations are industrial development bonds within the meaning of section 103(c)(2). For the interrelationship of the rules provided in this section and the exemption for certain small issues provided in section 103(c)(6), see §1.103-10.
(b) Definition of an industrial park. For purposes of section 103(c)(5) and this section, the term “industrial park” means a tract of land, other than a tract of land intended for use by a single enterprise, suitable primarily for use as building sites by a group of enterprises engaged in industrial, distribution, or wholesale businesses if either—
(1) The control and administration of the tract is vested in an exempt person (within the meaning of paragraph (b)(2) of §1.103-7), or
(2) The uses of the tract are normally (i) regulated by protective minimum restrictions, ordinarily including the size of individual sites, parking and loading regulations, and building setback lines, and (ii) designed to be compatible, under a comprehensive plan, with the community in which the industrial park is located and with the uses of the surrounding land.
(c) Development of land defined. For purposes of section 103(c)(5) and this section, the term “development of land” includes the provision of certain improvements to an industrial park site if such improvements are incidental to the use of the land as an industrial park. Such incidental improvements include the building or installation of incidental water, sewer, sewage and waste disposal, drainage, or similar facilities (whether surface, subsurface, or both). Such incidental improvements include the provision of incidental transportation facilities, such as hard-surface roads (including curbs and gutters) and railroad spurs and sidings; power distribution facilities, such as gas and electric lines; and communication facilities. The provision of structures or buildings of any kind is not included within the meaning of the term “development of land,” except for those structures or buildings which are necessary in connection with the incidental improvements encompassed by the term, such as, for example, a water pumphouse and storage tank needed in connection with the incidental provision of water facilities in an industrial park.
