Seattle holds the lowest office occupancy rate among 92 studied U.S. cities, with downtown vacancies reaching 35.8 percent. The market reflects a sharp decline in commercial property values, evidenced by the recent $12 million sale of the Plaza 600 building.
Why it matters
The persistent vacancy problem, which resulted in the loss of 13,000 downtown jobs in 2025, forces operators to weigh the long-term viability of central business districts. Analysts estimate it will take 16 years to fully refill the area's vacant space.
The Plaza 600 building sold for $12 million, reflecting an 87 percent decline from its $97 million valuation seven years ago. Seattle now faces a citywide vacancy rate of 32.7 percent, compared to the 20 percent national benchmark.
The players
Cushman and Wakefield
A global commercial real estate services firm that tracks market data and property performance for institutional investors and operators.
Plaza 600
A downtown Seattle commercial office property that recently sold for 87 percent less than its 2019 valuation.
The details
The sale of the Plaza 600 building underscores a structural shift in how Seattle real estate is priced as remote work reduces demand for traditional office footprints. With 13,000 fewer jobs in the downtown area during 2025, commercial landlords face prolonged vacancy periods that ripple through the local economy. The current vacancy rates are significantly above the 20 percent national average, signaling a deep correction that property owners and tenants must now integrate into their long-range financial planning.

Market Landscape
Seattle's office market currently sits at the extreme end of the post-2020 shift in U.S. office occupancy trends. The data marks a stark departure from previous valuations, following a pattern where office-heavy districts across the U.S. struggle to adapt to reduced tenant demand.
Operators in Seattle should prepare for a sustained 16-year window of downtown vacancy, which will likely influence commercial lease negotiations and property tax assessments. Business owners should consult with their tax advisors regarding potential adjustments to their real estate portfolio valuation.
The takeaway
The drastic devaluation of landmark assets like the Plaza 600 illustrates the volatility of urban commercial real estate in the current economic climate. Business owners should closely monitor regional vacancy metrics as a primary indicator for future lease leverage and potential shifts in local infrastructure investment.
