About this home

Tucked away off a private country road, this home is surrounded by native trees for enhanced privacy. The home has two bedrooms up and one down that are finished. Lower level large family room area and bedroom to finish to turn this home into a 4 bedroom home or the potential for an accessory dwelling (MIL). The setting for this home is wonderful. It is private, off the road so you don't hear the traffic and it opens up to approximately 3 acres of open meadow. Perfect Vashon property!

RA-5

Rural Area Zone

The purpose of the rural zone (RA) is to provide for an area-wide long-term rural character and to minimize land use conflicts with nearby agricultural or forest production districts or mineral extraction sites. These purposes are accomplished by: Limiting residential densities and permitted uses to those that are compatible with rural character and nearby resource production districts and sites and are able to be adequately supported by rural service levels; Allowing small scale farming and forestry activities and tourism and recreation uses that can be supported by rural service levels and that are compatible with rural character; Increasing required setbacks to minimize conflicts with adjacent agriculture, forest or mineral zones; and Requiring tracts created through cluster development to be designated as permanent open space or as permanent resource use.; Use of this zone is appropriate in rural areas designated by the Comprehensive Plan as follows: RA-5 in rural areas where the predominant lot pattern is five acres or greater but less than ten acres in size and the area is generally environmentally unconstrained

Permitted uses

Include but are not limited to:

Livestock production
Winery & vineyard
Housing-Other
