South Main Street Historic District
Why it's listed
South Main Street in Mount Morris is lined by one of the village's premier residential neighborhoods, and this district takes in both sides of a three-block section. It contains 30 houses, 27 of them contributing, plus 13 contributing outbuildings, mostly carriage barns and garages, and 7 non-contributing buildings. Construction dates run from about 1850 to 1925, with most buildings from the late nineteenth century. Houses are mainly wood-framed, with some brick, and range from one and a half to two and a half stories in Greek Revival, Second Empire, Italianate, Queen Anne, Colonial Revival, Foursquare and Prairie styles. Wide, tree-lined streets and large landscaped lawns frame the buildings. Focal points include a Greek Revival house at 145 South Main with a monumental Neoclassical portico, a Georgian Revival brick house at 140, and a Second Empire double house at 154. The boundary excludes heavily altered or modern buildings, so the district reads as the village's largest and most impressive group of high-style homes.
Significance in brief: The form describes the district as the largest and most impressive collection of predominantly high-style domestic architecture in the village. It shows a broad range of popular American styles, with grand mansions as focal points. The boundary includes only contiguous buildings that keep a high degree of original integrity.

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).
