The purpose of the R-1-8 zone is to allow for the establishment of single-family homes organized in low-density residential neighborhoods characteristic of traditional suburban residential developments.

Permitted uses in the R-1-8 zone are as follows:

1. Single-family detached dwellings; and
2. Accessory buildings customary to single-family housing.

Conditional uses in the R-1-8 zone are as follows:

1. Churches and private non-profit recreational grounds associated with that use;
2. Planned unit developments;
3. Public and quasi-public use;
4. Wireless telecommunication towers; and
5. Home occupations.

The minimum lot size in the R-1-8 zone is 8,000 square feet.

The minimum lot width in the R-1-8 zone is 70 feet, measured 20 feet from the front lot line.

1. Setbacks/yard requirements are intended to provide a description of the required space between buildings and property lines. The primary building shall maintain a minimum distance from property lines as follows:
   1. Front: 25 feet.
   2. Sides: On interior lots, a total of at least 20 feet between the two side yards, with no side yard of less than eight feet. On corner lots, at least 20 feet on the street side and at least 8 feet on the interior side.
   3. Rear: 20 feet.
2. Accessory buildings in the R-1-8 zone shall maintain a minimum distance from property lines as follows:
   1. Front: Accessory buildings, including detached garages, shall maintain a setback of at least six feet from the primary building in the rear yard of the particular property.
   2. Sides: Three feet on interior lots; 20 feet on the street side of corner lots.
   3. Rear: Three feet on interior lots; 20 feet on the street side of corner lots.

1. For uses where the slope of the original ground surface is greater than 15%, or if a slope stability hazard is present on site, the maximum structure height shall be 30 feet.
2. All other properties shall maintain a maximum structure height of 35 feet.
3. No accessory structure shall exceed 20 feet in height. For each foot of height over 14 feet, accessory structures shall be set back from property lines an additional foot from the minimum setback to allow a maximum height of 20 feet.

The maximum lot coverage in the R-1-8 zone is 50%, including all structures, except portions of those properties also located in the Sensitive Lands Overlay Zone, for which the maximum lot coverage shall be 30% including all structures and impervious surfaces.

The minimum open space requirement for developments over five acres in the R-1-8 zone is ten percent for standard subdivisions. For PUD’s, the minimum open space shall be determined by the planning commission, but shall not be less than 15%.
