Trenton, the capital of New Jersey, boasts a flatiron building, the Griffith Building. Located at the intersection of Broad and Second Streets, it was built in 1938 for Griffith Electric Supply Company.

In Atlanta, the Flatiron Building, eleven stories, was built in 1897. Its architect was Bradford Gilbert. It was originally named the English-American Building, built for the English-American Loan and Trust Company, and renamed the Empire Life Building in 1910, which name lasted for six years. It has a steel frame set in limestone piers.
