King County has 23 designated Qualified Opportunity Zones concentrated in Seattle neighborhoods including South Seattle, White Center, Rainier Valley, and the Central District, as well as in communities in Auburn, Renton, and Federal Way. Seattle's OZ footprint reflects the region's geographic constraints, surrounded by water and mountains, which have concentrated housing demand and investment pressure into a relatively small number of OZ-eligible urban neighborhoods.
King County's OZ investment case is anchored by Seattle's extraordinary technology economy, home to Amazon, Microsoft's Puget Sound campuses, and a dense concentration of technology companies, which drives relentless housing demand in OZ-eligible neighborhoods. South Seattle and White Center have attracted significant multifamily investment driven by the Link Light Rail's Rainier Valley and Federal Way extension routes.
What is an Opportunity Zone census tract?
Each Opportunity Zone is defined at the census tract level by the U.S. Census Bureau. Investors must deploy eligible capital gains into a Qualified Opportunity Fund (QOF) that invests in property or businesses within these designated tract boundaries. The tract GEOID numbers listed above identify each designated zone in King County.
How do I invest in King County Opportunity Zones?
Investments must be made through a Qualified Opportunity Fund (QOF). Capital gains must be reinvested within 180 days of the gain recognition event. Consult a qualified tax advisor to determine your eligibility and structure your investment. You can also visit our Find OZ Help page to connect with an OZ specialist.
