The building is currently totally vacant and closed to public entry. Plans for renovation to convert the building to hotel and apartments have repeatedly failed. The building stands abandoned and fenced off as of May 2016. The building has been condemned by Shelby County Environmental Court since late 2015 when it was discovered that chunks of concrete were falling from the building's exterior walls, as well as the elevators being inoperable and the fire safety systems not being up to code or functional. It was listed on the National Register of Historic Places in 2015.
