The purpose of the low-density residential (R-7) zone is to implement the low-density residential land use designation and policies of the comprehensive plan. The R-7 is intended to establish low-density residential home sites with a minimum gross acreage of 7,000 square feet. To do this, the R-7 low-density residential zone regulates the construction of detached single-unit dwellings and middle housing on existing lots, and provides design guidance for low-density residential subdivisions.
