According to Utah code, since Spring City is a small town, it is able to combine its demographics with other surrounding towns in regards to state requirements for low income housing. Accordingly, because of the great number of apartments available in these other towns (including the city of Ephraim) and pursuant to Spring City's general plan, specifically its desire to maintain low population density, no row or apartment houses, other than duplexes or two-family residences as outlined in zone R-MF shall be allowable within the city. Such dwellings may not be erected, sold, leased, or rented as individual units or apartment residences. (Ord. 2005-17, 9-8-2005)

In accordance with the above rationale, duplex houses shall not be allowed in Spring City other than within the R-MF zone. Accordingly, excepting the light commercial zone LC-1 (see SCMC 10-6, article D), no apartment shall be allowable in any zone in Spring City. Short term guesthouses may be allowed in some zones (see individual zones under SCMC 10-6, "Zones And Districts"). For definitions of apartment and guesthouses, see SCMC 10-1-3, "Definitions". (Ord. 2005-17, 9-8-2005) No apartment shall be allowable in any zone in Spring City except as otherwise specifically provided in any Spring City ordinance.
