East Main Street Historic District
Why it's listed
East Main Street Historic District is a compact residential neighborhood of about 24 acres in Hillsboro, Ohio, immediately east of the downtown business area. Its 86 buildings, mostly brick, include simple I-houses and half-houses, fifteen Italianate homes, Gothic Revival and Queen Anne houses, a Second Empire house, and two large churches. Wide streets and mature shade trees frame buildings that have seen few alterations. The district was listed for its architecture and its history. Many houses belonged to early settlers, merchants, bankers, mill owners and manufacturers who shaped the town's growth. The Highland House, built 1842-44, later served as a hotel and now houses the county historical society museum. The district is also tied to the 1873 Women's Temperance Crusade, which began in Hillsboro. Nearly a quarter of its homes are associated with the original Crusaders, and the Presbyterian Church served as the movement's focal point.

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).
