40.260.072 Compact Lot Developments
A. Purpose.
The purposes of the compact lot development provisions are:
1. To encourage development of underutilized and challenged parcels within developed portions of the low-density residential districts by providing flexibility for smaller, more efficient housing.
2. To diversify the county’s housing stock by providing a variety of housing types, sizes and price points that responds to changing household sizes and ages, such as retirees, small families, and single-parent households.
3. To encourage development in existing residential areas by allowing a density bonus and design flexibility.
4. To mitigate potential impacts of density and narrow lots through site design balancing community connections and privacy.
5. To integrate developments into existing neighborhoods.
