Buick City: from Flint auto complex to new industrial park

Buick City was less like one factory and more like a whole manufacturing neighborhood. By the 1980s, nearly 28,000 people worked across its buildings and operations on Flint’s north side, according to the Michigan Strategic Fund. The University of Michigan Library tells the same story another way: UAW Local 599 reached 28,000 members in 1979, most of them tied to Buick City.

That scale explains the name. The campus held assembly, foundry, parts, and other work on one broad stretch of property. Buick moved to Flint in 1903 and became part of General Motors when GM formed in 1908, so this ground sits close to the beginning of Flint’s long car story. You may see Buick City called the world’s largest GM complex, but the strongest official histories we found do not establish that comparison. The documented size and workforce are striking enough without it.

Vehicle assembly ended in 1999. After GM’s 2009 bankruptcy, the former Buick City property became part of RACER Trust, which was created to clean up and position old GM sites for reuse. That work is not simply finished and filed away. Michigan EGLE still describes corrective action at the roughly 413-acre site, including work involving soil, groundwater, sewers, and PFAS. EGLE leads the oversight, with the U.S. EPA supporting it.

Reuse is underway at the same time. A developer bought more than 300 acres in two 2023 transactions for the Flint Commerce Center. The first phase is a 330,000-square-foot industrial building; RACER’s current case study says Victory Packaging leases about half of it and reports 30 jobs there.

The bigger numbers need one more sentence of context. Plans call for as many as 10 buildings, about 3.5 million square feet, roughly $300 million in total investment, and around 2,500 jobs. Those are projections tied to a buildout that will follow market demand, not a description of what is complete today. So the honest picture is in between: Buick City is no longer just empty ground, but it is not yet the finished industrial park shown in the plans either.
