Originally Published: ConnectCRE

The Rush Companies and Timberlane Partners have recently completed the construction of Sumner Mill, a new 162-unit, three-story apartment complex. Timberlane Partners developed the 5.7-acre project, with nine buildings designed by Casey + DeChant Architects.

Located at 5816 162nd Ave E, Sumner, Washington, Sumner Mill features 162 studio, one, and two-bedroom apartments. Developed on 5.7 acres, the property comprises nine three-story, garden-style buildings situated 1.5 miles east of the Sumner Transit Station.

The project team broke ground in the fall of 2022, and resident move-ins began at the beginning of 2024. The team also included JPMorgan Chase, the construction lender. Northmarq helped secure nearly $49 million in funding. Amenities at Sumner Mill include an outdoor pool, clubhouse with kitchen, gym, conference room, pool table, package room, picnic area and barbecue stations.
