Delavan Commercial Historic District

Why it's listed
Locust Street forms the spine of Delavan's historic downtown in Tazewell County, Illinois, where 26 buildings stand in a two-block area, 20 of them contributing. Nearly all date from before 1900 or shortly after. The oldest, at 404 and 406 Locust, are Italianate brick stores from about 1860. Later buildings add more ornate Italianate cornices and window hoods, and the Masonic Hall at 401 Locust carries a Queen Anne turret. The street's most striking feature is its pressed metal upper fronts and its cast iron storefront columns and pilasters, which rarely repeat a design. A fire in 1888 destroyed five wooden buildings on the west side, and masonry replacements followed. A 1911 stone-faced concrete block lodge building marks the later end of the range. The district is significant as a record of commercial architecture in a farm and grain-shipping town that grew with railroads and surrounding agriculture.

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).
