Top 10 Largest Multifamily Conversions in the Pacific Northwest

The area recorded a high number of adaptive reuse projects that transformed hotels into affordable multifamily communities, breathing new life into historic buildings. Some of the structures served military purposes during World War II.

Adaptive reuse continues to be a growing trend in high-density markets, contributing to the revitalization of the urban landscape and creating new opportunities for businesses and residents. The largest metros in the Pacific Northwest, Seattle and Portland, have recorded strong population gains in the past years, which led to a rise in household formation and a need for more low-income housing.

A particularity of the area is the conversion of hotels into affordable multifamily communities. This option has become increasingly appealing since government programs such as Housing Opportunity Bond or Portland’s 10-year plan to end homelessness provide support for such projects.

The list below includes the largest conversion projects in the region and is based on Yardi Matrix multifamily data. The compilation takes into consideration the unit count for redeveloped apartment properties across the Pacific Northwest.

10. The Senator in Yakima, Wash.

The 161-unit community is located at 20 E. Staff Sgt. Pendleton Way in Yakima, right in the heart of Washington state. The Senator encapsulates the former Sydney and Roza hotels, built in 1909 and 1914, respectively. The structures, interconnected through a skybridge, have been converted into a residential property in 1977.

The Class C apartments feature 146 single-room occupancy units of 300 square feet each and 15 one-bedroom units of 600-square-foot each.
