Coworking expands, vacancies to stay elevated
As of September, the national office vacancy rate stood at 18.6 percent—down 80 basis points over the past 12 months. As a result of lasting changes in the office landscape after the start of COVID, the flex office sector expanded notably, reaching 2.1 percent of the total office inventory.
Chicago is one of the markets that registered the largest increase on a year-over-year basis—up 60 basis points and with a coworking footprint representing 2.6 percent of its existing office stock. Meanwhile, as the coworking footprint grew faster than its location count, the average flex office space also increased by 2.1 percent to 18,080 square feet.
