Downtown Seattle saw a gain of 300,000 square feet in occupied office space during the third quarter of 2026. Despite this growth, the downtown vacancy rate remains at 35.4% as the market continues to navigate post-pandemic shifts.
Why it matters

This drive for premium space follows a period where twenty of the city's most valuable buildings saw a 53% drop in taxable value.
Downtown Seattle recorded 300,000 square feet of newly occupied space in Q3 2026, though the market continues to face a 35.4% vacancy rate. Over 80% of recent leasing activity involved Class A buildings.
