The Arc Legacy Center

Where the IDD Community Thrives – A Lasting Home in SeaTac

Welcome to The Arc Legacy Center, a place where accessibility, inclusion, and community come to life. Step through the doors of our new home and you’ll experience a beautiful space where every detail says: you belong here.

Designed in partnership with Mercy Housing Northwest, the building will also offer 130 affordable apartment homes. We’re thrilled 26 units are reserved expressly for individuals with IDD and referred by The Arc of King County. Direct access to the Angle Lake light rail station takes residents to work, school, and services easily. 

We’ve made great progress in fundraising, with pledges and gifts taking us to 73 percent of our $7.7M goal. These early gifts have created a strong foundation and momentum on which we will grow. But we can’t do this alone – we need your help to bring The Arc Legacy Center to life. 

The Arc Legacy Center is more than just a building – it’s a promise. A promise to the IDD community that there will always be a safe and inclusive place. 

This is our moment to come together and build something that lasts, something benefiting generations to come, something truly transformative. Every gift matters – big and small – every gift will help us make this space for the IDD community a reality.
