Attention Builders and Investors. Rare opportunity with multi-family zoning on a 20,238 sq ft vacant lot in the heart of Burien. Land use approval already in place for three duplexes (six total units)—a valuable head start for your development timeline. Located just a few blocks from downtown Burien’s city center, offering immediate access to shops, restaurants, grocery, transit, and year-round community events. Minutes to I-5, SeaTac Airport, Westfield Southcenter Mall, and major employment hubs, making this an ideal location for future tenants or resale. A strong opportunity for builders seeking a shovel-ready project or investors looking to capitalize on Burien’s growing demand for multi-family housing.
