807 4th Avenue presents a rare opportunity to acquire a high-density development site in the center of Downtown Seattle's Financial District. Positioned on the southeast corner of 4th Avenue and Columbia Street, the property is entitled by DOC1 zoning, allowing for a proposed 55-story mixed-use tower in one of the city's most established business and residential districts. The site offers an estimated 1,126,844 buildable square feet and is strategically located across from Columbia Center, within walking distance of major employers, civic institutions, hotels, restaurants, and transit connections. The location benefits from exceptional pedestrian and transit accessibility, reflected by a Walk Score of 99 and Transit Score of 100. Future residents, hotel guests, or commercial occupants would have direct access to Seattle's central business district, Pioneer Square, First Hill, Capitol Hill, and South Lake Union, providing connectivity to many of the region's primary employment and lifestyle destinations. Conceptual planning for the site includes a residential tower with integrated retail, parking, and amenity components designed to capitalize on protected urban and regional views. Existing parking operations provide interim income potential while future development plans are pursued. Seattle remains one of the Pacific Northwest's leading employment centers, supported by major technology, healthcare, education, and professional service employers, reinforcing long-term demand drivers for high-density urban development. The combination of scale, zoning capacity, central location, and redevelopment flexibility positions 807 4th Avenue as a significant development opportunity within Seattle's evolving downtown market.
