The board of adjustment may grant temporary use permits for the location of temporary structures, in connection with permitted uses, on the site of such permitted use, which use is either existing or about to be established, upon the construction of a permanent structure. Such temporary structure shall provide facilities during construction of permanent facilities which are an addition to the permitted use or which will result in permanent facilities to house the permitted use. For example, but not by way of limitation, such temporary use permits may be issued to permit the parking of a trailer housing banking facilities, temporary office space, temporary classroom space and/or temporary warehouse space on such a site.
