South Main Street District
Also known as: See Also:Tytus, John B., Mansion
Why it's listed
South Main Street in Middletown, Ohio, forms a 40.5-acre historic district that moves from a commercial block at the north into a tree-lined residential area. Its buildings date mainly from the late 1800s and early 1900s, and they show a wide range of styles, from Victorian Italianate and Queen Anne to Romanesque, Shingle, Greek Revival, Tudor and Carpenter Gothic. The oldest house dates from 1827 and the newest from 1927. Notable buildings include the 1887 Sorg Mansion of red limestone, with turrets and gargoyles, the 1890 Sorg Opera House and the 1831 U.S. Hotel. As the town's commercial center grew eastward, prosperous industrial leaders built or enlarged homes on this street. Surviving features include iron fences, granite curbs, hand-carved staircases and Rookwood fireplaces. The district was listed for its intact architectural character and its link to the people who shaped Middletown's growth.
Significance in brief: The nomination argues the district's main value is its intact collection of late 19th and early 20th century architectural styles, including Victorian, Romanesque, Queen Anne, Shingle, Greek Revival, Tudor and Carpenter Gothic. It also holds that the street was home to industrial leaders who shaped Middletown's history and whose innovations spread nationally and worldwide.

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).
