About Comerica Tower
One Detroit Center, also known as Comerica Tower at Detroit Center after its tenant, is a skycraper located downtown in the the city's financial district (500 Woodward Ave. Detroit, Michigan 48226). Rising 619 feet (189 m), the 43-story tower is the tallest office building in Michigan, and the second tallest overall in the state behind the central hotel tower of the Renaissance Center, located a few blocks away. Although the Penobscot Building has more floors (45 above-ground floors compared to 43), One Detroit Center's floors are taller, with its roof sitting roughly 60 feet (18 m) taller than Penobscot's. Its floor area is 1,674,708 square feet (155,585 m). The building is occupied by tenant Comerica Bank which, in an effort to further expand, announced it would move its corporate headquarters to the Comerica Bank Tower in downtown Dallas, Texas in 2007, but maintain its presence in Michigan. The bank has engaged in a succession of takeovers in other states including Texas, Florida, and California. The bank's lease on Comerica Tower at Detroit Center runs through 2012.
