This district is composed of certain quiet, low-density residential areas of the city plus certain open areas where similar residential development appears likely to occur. Mobile homes shall also be permitted on individual lots. The regulations for this district are designed to stabilize and protect the essential characteristics of the district, to promote and encourage a suitable environment for family life where children are members of most families and to prohibit activities of a commercial nature. To these ends, development is limited to single-unit dwellings providing homes for the residents plus certain public facilities, which serve the residents of the district. The regulations set out in this chapter shall apply to all R-4 districts.
