Single-Family Residential District

This District is reflected on the General Plan Land Use Map as Single-Family Residential, which allows a density range of between 1 and 6 residential units for each acre of land, with a maximum population density of 18 persons for each gross acre of land. The minimum lot area for R-1 lots shall also be regulated by the Slope Density Table, referred to as Table 4C. No allowance for rounding up shall be granted for the last lot in a subdivision which only partially meets the minimum lot area requirements. This District is generally applied to established residential neighborhoods characterized by single-family detached residential units on conventional lots. The majority of the land area in this District has previously been developed. Additionally, this District is applied to lots located at or above 150 ft above Mean Sea Level which are further regulated through the requirement for the careful review of architectural design and site development characteristics for new development on undeveloped land, for certain reconstruction of existing development, and for certain expansions of existing development. Accessory dwelling units are permitted as an accessory residential use that is consistent with the General Plan and shall not be considered to exceed the allowable density. Small 2 unit developments that comply with Chapter 4 are permitted.
