Seattle’s downtown office market continues its dramatic decline, with vacancy rates climbing to an unprecedented 37 percent as commercial real estate experts warn the city could be left with a growing number of so-called “zombie buildings,” office towers that sit largely empty with little prospect of attracting new tenants.
The grim assessment comes in a new Seattle Times report examining the ongoing collapse of downtown’s office market, a trend that has accelerated since the COVID-19 pandemic but has been compounded by business relocations, layoffs, and concerns over Seattle’s economic climate.
According to data cited by the Seattle Times from the King County Assessor’s Office, downtown office buildings have lost approximately $15 billion in assessed value since 2020, a 46 percent decline. The reduced property values have also translated into an estimated $128 million annual loss in property tax revenue, placing additional pressure on local governments already facing budget challenges.
Seattle’s office vacancy rate now stands at 37 percent, significantly worse than other major metropolitan areas.
For comparison:
- New York City: 22%
- National average: 23%
- San Francisco: 31%
- Los Angeles: 32%
- Seattle: 37%
The vacancy rate has continued climbing despite repeated predictions that office workers would eventually return to downtown.
Over the past year, several major employers have announced expansions outside Washington while reducing their footprint in the Puget Sound region.
Microsoft recently announced another round of layoffs affecting approximately 4,800 employees worldwide, including workers in Washington. Meanwhile, Starbucks has confirmed plans to establish a major corporate hub in Nashville. Former Starbucks CEO Howard Schultz announced earlier this year that he had relocated to Florida after publicly criticizing Washington state’s increasingly difficult business climate.
Amazon and Meta have also continued reducing office space and restructuring portions of their workforces while expanding operations in lower-cost states.
Business groups have repeatedly warned lawmakers that the state’s tax policies are discouraging investment. Earlier this year, the Association of Washington Business reported that 91 percent of surveyed employers do not plan to expand in Washington, while nearly one-quarter said they are considering relocating operations elsewhere.
Commercial real estate experts told the Seattle Times that unless demand rebounds substantially, Seattle may see an increasing number of underutilized office towers becoming financially unsustainable. Those buildings—often described as “zombie buildings”—remain technically occupied but generate too little revenue to support significant investment or redevelopment.
Some office conversions into residential housing have been proposed, but experts say many Seattle skyscrapers are poorly suited for such projects because of their floorplates, plumbing layouts, and conversion costs.
With office vacancies still climbing rather than stabilizing, the city’s commercial core faces an uncertain future. Every empty floor not only represents lost rent for building owners, but also fewer downtown workers supporting restaurants, retailers, transit systems, and the city’s tax base.
For Seattle, the concern is no longer simply whether employees will return to the office—it is whether the city’s economic policies can convince employers to continue investing there at all.
