This chapter establishes the standards for the location and development of manufactured homes, mobile home parks and manufactured home subdivisions. The manufactured home standards are intended to allow manufactured homes in all areas of the City in which single-family residences are a permitted use. The mobile home park is intended primarily to accommodate planned mobile home developments in a desirable residential environment thereby providing a greater range and choice of housing types. These developments are intended to accommodate individual manufactured homes or mobile homes on a condominium lot sale basis or lot rental or lease basis so that the park remains in one ownership to comply with the conditions of development.
