Minneapolis CBD leads in large leasing deals Vacancy rates in Minneapolis CBD continue their trend of shrinking every quarter. Vacancy at IDS Center declined 250 basis points since 2014 and the building now has its lowest quarterly vacancy in recent years. The demand for premium downtown office space is substantial and even co-working firms are getting in on the craze. Recently, two shared-space companies out of Chicago, Industrious and Assemble, leased a collective 36,000 sf with plans to rent out collaborative workspace to entrepreneurs and small firms by end of year.
