Eichner had sold 280 of the apartments and three-quarters of the office space by early 1989,[1] and the building was completed by 1990.[2] CitySpire's dance studios were supposed to be completed in September 1989, but it was not until mid-1990 that Eichner applied for a permit. Construction on the studios had not even started because, according to Hornstein, the plans had to be approved by several agencies.[3][4] Eichner still had yet to sell the 50 remaining apartments and the remaining 20 percent of commercial space. Ten of these apartments were in the top stories that could not be completed until the studios were finished.[107][108]
