Mahoning National Bank Building
Why it's listed
Rising thirteen stories at the southwest corner of Central Square in Youngstown, this steel-frame office building was designed by Albert Kahn and completed in 1910. It was originally five bays wide, and fourteen years later it was doubled in width to its present ten bays. Terra cotta piers give the facade a strong vertical emphasis, and each rank of piers is topped by a Florentine Romanesque arch. It has been described as the finest terra cotta clad Commercial style building in the city. As one of the early office buildings on the square, it housed real estate, land and mortgage offices, along with coal, oil and gas companies, and its primary tenant was Mahoning National Bank. Its architecture and its link to a major American architect form the basis of its significance. The building is visually and physically tied to the Central Tower on the west side of the square, and it remains in office use in excellent condition.
Significance in brief: The building is described as the finest terra cotta clad Commercial style building in the city and a distinguished design by major American architect Albert Kahn. It was one of the early office buildings on Central Square and housed real estate, land, mortgage, coal, oil and gas offices alongside Mahoning National Bank.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
