Sound Transit Leases 31,000 SQFT at 5th & Jackson Building Near Union Station in Seattle’s Pioneer Square

The Central Puget Sound Regional Transit Authority has committed to 31,000 square feet of new office space at 315 5th Ave. S., the 5th & Jackson building near its Union Station headquarters, bringing the light rail agency back to a Pioneer Square building where it leased office space for more than a decade and putting a dent in a submarket where more than a third of office space sits empty.
