Seneca

YWCA Seneca was the first purpose-built location in Seattle created specifically for the benefit of women and girls. Designed and constructed from 1912 - 1914, it housed a variety of services to meet the needs of local young women, including hotel accommodations and educational and social facilities. The building was designed by Pacific Northwest architect E.F. Champney who also designed the 1909 Alaska-Yukon-Pacific Expo in Seattle. It was added to the National Register of Historic Place in 2006.

In 2023, the building closed to undergo a major rehabilitation project to preserve and protect the housing and services at this location. This project will ensure the long-term preservation of housing and service delivery at YWCA Seneca. The top five floors of the existing structure were renovated to construct 114 new units of permanent housing for low-income and formerly homeless residents (98 studios, 16 one-bedrooms). The rehabilitation included other significant improvements for the building: all major systems were replaced and the first two floors were redesigned, while historical elements of the exterior and interior were preserved. 

Funding for this project came from the City of Seattle Office of Housing, low-income housing tax credits, and other private and public partners.
