The R-2 Two-Family Residential District is composed of certain medium-density residential areas of Richland Township representing compatible mingling of single-unit and double-unit dwellings, plus certain open areas where similar residential development appears likely to occur. 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; and to prohibit all activities of a commercial nature except certain home occupations. To these ends, development is limited to a relatively medium concentration and permitted uses are typically single-  and two-unit dwellings, providing homes for the residents in this choice of dwelling types plus certain additional uses such as schools, parks, churches and certain public facilities which serve the residents of the district.
