FWIW, the United Artists Building is part of the "District Detroit" RFP:

From Crain's:

"The United Artists Building is planned for about 75 multifamily units, the RFP says. According to a source, the redevelopment is expected to include first-floor retail space and a repurposing of at least some of the theater inside the 223,000-square-foot building, which was constructed in 1935 and has been owned by the Ilitches since 1997."
