17600 SE Cougar Mountain Drive

Issaquah, WA 98027

Opportunity! Perfect for a builder or investor looking to unlock this property's full potential. This property is served by City of Bellevue water and sewer and is located within the Urban Growth Area of unincorporated King County. Based on current regulations, the site allows the opportunity for up to three separate building permits, three addresses, and three separate tax parcels. Homes of approximately 3,400 square feet may be possible, with potential for a larger primary residence. The property also offers beautiful Cascade Mountain views. One of the unique advantages of this property is its location within the Urban Growth Area while remaining under King County jurisdiction, allowing buyers to take advantage of favorable county development standards. Unlike many properties that cannot fully benefit from recent land use changes, this site appears well positioned to do so. Based on the attached feasibility analysis, development may proceed through the residential building permit process rather than a discretionary land use review process, potentially providing a more streamlined path to development. The lot is zoned R-1 and, due to its size, will allow up to 55% impervious surface coverage under current King County regulations. Buyers should review all attached feasibility information and independently verify development potential to their satisfaction. Please review the attached documents and contact the co-listing agent, Cliff Mull, with any questions.
