I took these numbers from a survey that was done almost a year ago, and they have probably improved since then.

I took a guess at the building class, although I know the vacancy rates for each class is right because they tie out to the survey (which doesn't specifically identify which buildings fit into which category).

Some interesting observations:

  1. Class A space inventory is tight; less than 15% available and no large contiguous blocks
  2. Almost half the entire vacant space in the CBD is from the First National Center, which is Class C space in it's current form
  3. If that space was converted to housing or leased, downtown vacancy would be under 15% overall -- very low
  4. Vacancy rates have been trending steadily downward for five years and rents have been going up accordingly
