City Hall Annex
Also known as: Federal Post Office

Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
Built in 1932-33 at 9 West Front Street in downtown Youngstown, this three-story steel-frame building served as the city's third main post office. Its smooth sandstone facade has a rusticated ground story, round-arched windows in two entry pavilions, and a classical cornice and parapet with balustraded openings. The building cost $585,000 and replaced an 1898 post office that had become too small as Youngstown's population grew from 45,000 in 1900 to 170,000 in 1930. Its design echoes the nearby 1910 Mahoning County Courthouse in scale, stone walls and classical detailing, and the two together mark this part of downtown as a governmental center. It also reflects the classical post office style encouraged nationwide in the 1930s. The post office function ended in 1975, when the city bought the building for use as a City Hall annex. The original marble and terrazzo lobby and the upper-floor office partitions remain intact, though most windows have been replaced.
Significance in brief: The nomination argues it is significant for serving as a federal office building for over 40 years, for its link to the local postal service, and for its classically inspired architecture. Its design was influenced by the neighboring Mahoning County Courthouse, and the two form a cohesive group of classical buildings. Its construction also reflects Youngstown's rapid population growth between 1900 and 1930.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
