Racine's Southside Historic District and the Main Street Lake Homes
The south side of Racine is the city's architecture district, and Main Street is its spine. The Southside Historic District was listed on the National Register in 1977, roughly bounded by Lake Michigan, DeKoven Avenue, Villa Street and Eighth Street, per the Racine County NRHP list. Its Wikipedia entry) counts more than 500 contributing buildings built from 1842 to 1924.
The houses read like a style catalog. The Eli R. Cooley House at 1135 Main Street is a Greek Revival house designed by Lucas Bradley and built from 1851 to 1854, which the NRHP list quotes as having been described as the state's finest remaining Greek Revival residence. The Chauncey Hall House at 1235 Main Street is one of the earliest surviving Gothic Revival houses in Wisconsin. The Henry S. Durand house at 1012 Main Street is an 1856 cream brick Italianate villa. The George Q. Erskine house at 920 Main Street is a High Victorian Italianate with a four-story tower, and the Joseph Miller house at 1100 Main Street is an 1893 Queen Anne with a round corner tower. The Charles Carpenter house at 1324 Main Street is an 1896 Georgian Revival with four Ionic columns, and the Samuel Curtis Johnson cottage at 1737 Wisconsin Avenue is a 1903 Picturesque Gothic cottage the S. C. Johnson founder designed himself.
The district also holds two modern landmarks. The Thomas P. Hardy House at 1319 Main Street is a 1905 Frank Lloyd Wright Prairie School house that steps down the bluff above Lake Michigan. Its street side is mostly stucco with an entry right at the sidewalk, while the lake side opens into a two-story living room. It was renovated from 2013 to 2015 and remains a private home. Wikipedia also notes the OS House, a LEED Platinum house by Johnsen Schmaling Architects on the shore in the same district, which the American Institute of Architects recognized in 2011.
On value, the 2026 roll shows the lake side of Main Street at a premium to the rest of the district. By my count, the 22 residential-only parcels on the odd-numbered side of Main Street from 800 to 1999 have a median assessment of $592,000 and a median lot of about 0.39 acre, against $459,300 for the 45 parcels on the even side. Only one Main Street home in that stretch is assessed above $1 million.
The rules matter before you buy. The city's historic preservation page says National Register listing is honorary in Racine and gives the city no added regulatory authority. Local landmarks are different: exterior changes there go to the city's Planning, Heritage, and Design Commission, and the page lists five current local landmarks, including 1135 and 1001 Main Street and 936 Main Street. The city also publishes residential design guidelines from 2022 for those properties.
