R1-6*
Single-Family Residence District
A basic purpose of these regulations is to foster the creation of living areas which can assist the establishment of stable, functional neighborhoods. An established pattern of living in this metropolitan area reflects a tradition of single-family occupied dwellings which also emphasize outdoor living. Many of these dwellings are thereby located on relatively large urban or suburban lots.; These regulations provide standards for dwellings built at low and moderate densities. While the predominant housing type is expected to be single-family dwelling, provisions are made for alternative housing types within the same density limits.
