Tenants[edit]

The law firm Dickinson Wright (formerly Dickinson, Wright, Moon, Van Dusen & Freeman) has its headquarters in Ally Detroit Center.[9][10] The company moved into the building when it opened in 1992.[11] In 2007, when it renewed its lease, the company occupied almost 100,000 square feet (9,300 m2) of space in the building.[10] Additionally, the international law firm of Clark Hill, PLC operates its headquarters on three floors of the building.


The building was previously occupied by Comerica Bank. The bank's lease on then Comerica Tower at Detroit Center ran through 2012, and in December 2009, Comerica announced it would vacate One Detroit Center at the end of the lease, consolidating its Michigan operations at 411 West Lafayette Boulevard.[12][13]


In March 2015, following the purchase of the building by Dan Gilbert through his Bedrock Real Estate Services, Bedrock and Ally Financial announced a 12-year lease under which it would move its main office into the building from the nearby Renaissance Center as well consolidate all employees in suburban Detroit to the building, occupying 20 floors or approximately 321,000 square feet (29,800 m2). The tower was renamed Ally Detroit Center.[14][15]


In 2015, a full service restaurant, Townhouse, opened in the first floor of the Ally Detroit Center, situated on the corner of Woodward and Congress.[16] In 2019, a Plum Market grocery store was opened in the first floor, with an entrance at the corner of Woodward and Larned.[17][18]
