These figures, provided by the local offices of Colliers International, paint a picture of sharp turns -- but when subleases are factored into the equations, the lines on analysts' graphs become even more dramatic.

The Eastside's office inventory totals just a bit more than 25.9 million sf, with 1.55 million sf of that running as direct vacancies. But, add to that 1.73 million sf of sublets, and the number spikes to 12.66%.

Bellevue's Central Business District and the Interstate 90 Corridor contain the two, largest chunks of the Eastside's sublease space. With 563,079 sf and 535,636 sf respectively, the two collectively account for 64.6% of the total. Of that, 97% is class A space.
