Single Dwelling Zones
The single-dwelling zones are intended to preserve land for housing and to provide housing opportunities for individual households. The zones implement the comprehensive plan policies and designations for single-dwelling housing.
- Use regulations. The use regulations are intended to create, maintain and promote single-dwelling neighborhoods. They allow for some nonhousehold living uses but not to such an extent as to sacrifice the overall image and character of the single-dwelling neighborhood.
- Development standards. The development standards preserve the character of neighborhoods by providing six different zones with different densities and development standards. The development standards work together to promote desirable residential areas by addressing aesthetically pleasing environments, safety, privacy, energy conservation, and recreational opportunities. The site development standards allow for flexibility of development while maintaining compatibility within the City's various neighborhoods. In addition, the regulations provide certainty to property owners, developers, and neighbors about the limits of what is allowed. The development standards are generally written for houses on flat, regularly shaped lots. Other situations are addressed through special regulations or exceptions.
