6.4. Alternative single-family options.

   The following alternative single-family residential options are allowed only in residential cluster developments .

   A.   Zero lot line.

      1.   Description. A zero lot line development is where houses in a development on a common street frontage are shifted to one side of their lot . This provides for greater usable yard space on each lot . These developments require that planning for all of the house locations be done at the same time. Since the exact location of each house is predetermined, greater flexibility in site development standards are possible while assuring that single-family residential character is maintained.

      2.   Setbacks. The side building setback may be reduced to zero on one side of the house. This reduction does not apply to the street side setback or to the interior side setback adjacent to lots that are not part of the zero lot line project. The reduced setback may be located anywhere between the lot line and the minimum setback required for the district. The remaining side yard setback shall be equal to two times the side yard setback required for the district.

      3.   Additional standards.

         a.   Distance between houses. The minimum distance between all buildings in the development must be equal to twice the required side setback required by the underlying zoning district. A deed restriction must be recorded on the deed of each applicable lot to ensure continued compliance with this setback.

         b.   Eaves. The eaves on the side of a house with a reduced setback may project a maximum of 18 inches over the adjacent property line. In this case, an easement for the eave projection must be recorded on the deed for the lot where the projection occurs.

         c.   Maintenance easement. An easement between the two property owners to allow for maintenance or repair of the house is required when the eaves or side wall of the house are within four feet of the adjacent property line. The easement on the adjacent property must provide at least five feet of unobstructed space between the furthermost project of the structure and the edge of the easement. The easement shall be recorded on the subdivisionplat.

         d.   Privacy. If the side wall of the house is on the property line, or within three feet of the property line, windows or other openings that allow for visibility into the side yard of the adjacent lot are not allowed. Windows that do not allow visibility into the side yard of the adjacent lot, such as a clerestory window or a translucent window, are allowed. All materials within three feet of the property line shall be fire-rated to meet building code requirements.

   B.   Village house. A village house may be permitted in a cluster development with a reduced front yard setback of 15 feet, provided that no front yard parking is allowed and alley or other rear access is provided for any garage.
