Zoning

Single-Family Residence Districts

The Single-Family Residence Districts, as differentiated herein, and the district locations as depicted on the Zone District Map, reflect the wide variety of physical and social characteristics found in Waterloo, to the extent that the range of such conditions and characteristics can be divided into meaningful categories. It is the purpose of these regulations to encourage the creation and maintenance of stable and enduring residential areas by establishing limitations on the use and character of development so as to take advantage of, or to avoid conflict with, natural topography, existing development, arrangements and locations of existing or planned community facilities and social needs of the city.
