Downtown Seattle’s swankiest office towers are watching their values fall faster than the elevator in rush hour. As vacancy rates spike, the city’s most expensive high-rises have seen their assessed values plunge, wiping billions off the tax rolls and leaving street-level storefronts noticeably quieter. The damage is concentrated in a small cluster of landmark skyscrapers that once symbolized the city’s tech boom, and the hit is now landing on landlords, retailers and municipal budgets alike. For many small businesses that count on weekday office crowds, the downtown “recovery” has felt uneven at best.
Big-Picture Numbers And The Tax Hit
The Downtown Seattle Association’s 2025 “At a Glance” report, based on county assessment records, found that the 20 downtown buildings with the highest taxable value dropped from more than $10.7 billion in 2021 to roughly $5.1 billion by 2026, a slide of about 53%. Property tax assessments tied to those same properties fell too, from over $100 million a year to roughly $50 million, according to the Downtown Seattle Association.
Which Towers Took The Biggest Beating
Local reporting that dug through King County Assessor records shows several marquee buildings lost more than half their assessed value. Amazon’s Doppler tower and meeting center logged roughly a 62% decline, the Day One Tower and Spheres came in around 59%, and other downtown icons, including the DocuSign Tower and the U.S. Bank Centre, posted drops in the mid-50s percent range. Taken together, the steep cuts at a handful of Amazon-linked and other trophy properties account for well over $1 billion in lost value at the top end of the market, as reported by MyNorthwest.
Vacancies And The National Backdrop
Industry data compiled by CoStar and summarized in recent coverage puts regionwide office vacancy near 17.3%, with forecasts that it could peak around 18.3% in 2026, while downtown vacancy is far worse. Downtown as a whole is near 25%, and the central business district is topping 32% in some measures. Those elevated vacancy figures have dragged down rent expectations and pushed assessed values lower, per Axios.
Street-Level Fallout
The office pullback is not just visible in dark windows on upper floors. It has rippled through ground-floor retail, where national chains such as Ross, Nike, Saks and The North Face have trimmed their downtown presence as weekday foot traffic thinned. The combination of empty office space and lower assessments has also opened a hole in the budget, with local outlets reporting property tax receipts coming in millions below projections in 2025, according to MyNorthwest.
What Leaders Say, And What Comes Next
Business and civic leaders are trying a mix of quick fixes and long-game strategies to juice demand downtown. That includes short-term activation such as events and programming, alongside longer-term ideas like incentives for office-to-residential conversions and targeted leasing strategies. "Downtown Seattle has experienced a healthy amount of momentum," DSA president Jon Scholes told reporters, while pressing for coordinated action to tackle structural leasing challenges and the still-lagging office comeback, according to Axios.
Property owners can and often do push back on assessment changes, and the King County Assessor’s office spells out how valuations are set and how appeals work for those who disagree with an enrollment. As the market works through new leasing deals and potential conversions, and with major events and transit expansions on the 2026 calendar, the shape of downtown’s recovery will hinge on a basic question: do employers refill office space at scale, or do landlords move more aggressively to repurpose those buildings for other uses, as explained by the King County Assessor.
