Studebaker Building, Automotive heritage building in downtown St. Petersburg, Florida.

The Studebaker Building at 600 4th Street South is an automotive dealership structure featuring Tudor Revival and Art Deco details designed to showcase and service motor vehicles. The structure combines a prominent ground-floor display area with extensive workshop and storage spaces typical of major car dealers from that era.

Built in 1925 for the Peninsular Motor Company, the Studebaker Building housed a dealership that, by that year, ranked fourth in sales volume among Studebaker dealers worldwide; 56 of its 300 employees worked in the St. Petersburg showroom. When the Florida land boom collapsed, the company went bankrupt in 1926 and the building closed. It was listed on the National Register of Historic Places on July 5, 1985.

The building carries the name of Studebaker, the automobile company whose cars the Peninsular Motor Company sold here from 1925; by then that dealer ranked fourth in the world for Studebaker sales volume. Of its 300 employees, 56 worked in the St. Petersburg showroom, a figure that shows how much of the trade was local sales and service rather than assembly.

The building sits in downtown St. Petersburg and now serves as a federal research facility, so visiting is limited to authorized purposes or scheduled open times. Its exterior architecture remains on display and communicates the history of automotive retail in the city.

When the building opened, the Peninsular Motor Company was the fourth-largest Studebaker dealer in the world, with 300 employees, 56 of them in the St. Petersburg showroom. Within a year the collapse of the Florida Land Boom bankrupted the company and the building closed.
