Why it's listed

North of downtown Monticello, the North State Street district runs through the 300 to 1100 blocks of a wide, tree-lined residential street. It lies between the Illinois Central Railroad tracks to the south and a small creek to the north. The district holds 77 buildings and outbuildings, including houses, garages and carriage barns. Fifty-six contribute to its character, and the buildings date from about 1870 to 1948. The other 21 are mostly modern garages built after 1948. Colonial Revival is the dominant style. Queen Anne, Craftsman, Tudor Revival and Gothic Revival examples also appear, along with vernacular types such as the I-House, T-plan, Cross plan and Bungalow. Most buildings are frame with clapboard siding, and brick is the common masonry material. Nineteen historic garages and carriage barns add to the setting. Most houses were built as single-family homes and still serve that purpose. Alterations are uncommon, so the district retains a cohesive early twentieth-century residential appearance with mature street trees and landscaping.

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).
