Why it's listed

Mahoning Avenue in Warren, Ohio, is a short residential street whose houses and one church record a century of architecture and political life. The boundary increase adds the structures on the eastern side of the street to the western half listed in 1971. The buildings range from Federal and Greek Revival to Victorian Italianate, Queen Anne and Romanesque Revival. The Smith House was built in 1828 by Isaac Ladd for Leicester King, and the Kinsman House followed in 1832. Henry B. Perkins's house drew Grant, Garfield, Hayes, Harrison and McKinley. The Harriet Taylor Upton House later served as national suffrage headquarters. The Adams House dates from the 1840s, and the First Presbyterian Church building was dedicated in 1876. The district was the center of Warren's social life and the setting for nationally important political activity. Demolitions and commercial growth threaten both ends of the street.

What listing means for this property

This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
