R1
Single-Family Residential District
These districts are composed mainly of areas containing one-family dwellings and open areas where similar residential development seems likely to occur; few two-family and multiple-family dwellings are found in these areas. The district regulations are designed to protect the residential character of the areas by prohibiting all commercial activities, to encourage a suitable neighborhood environment for family life by including among the permitted uses such facilities as schools and churches and to preserve the openness of the areas by requiring certain minimum yard and area standards to be met.
Permitted uses
Include but are not limited to:
Agriculture
Community / recreation center
