Frank Lloyd Wright-Prairie School of Architecture Historic District
Why it's listed
Oak Park's north-central neighborhood covers about 474 acres of former prairie laid out on a flat street grid. Detached wooden houses sit on lots of varied size behind continuous lawns and mature street trees, giving the streets a park-like character. Development began after the Civil War and was nearly complete by World War I, so styles run from Italianate through classical revival, with a notable body of early modern work. Frank Lloyd Wright settled in Oak Park in 1889, built his own house that year and a studio in 1897, and designed about twenty-five buildings in the village, most within this area. Roughly sixty-five more buildings come from Prairie School architects, including students and associates of Wright. The nomination describes this as the largest concentration of early modern architecture in the world, and says the district would likely have qualified for its suburban character and architecture from 1865 to 1917 even without Wright. Two boyhood homes of Ernest Hemingway are also here.
Significance in brief: The district holds about twenty-five Frank Lloyd Wright buildings plus roughly sixty-five more by Prairie School architects, which the nomination calls the largest concentration of early modern architecture anywhere in the world. It also reflects a well-preserved suburban streetscape with houses from 1865 to 1917, and includes two boyhood homes of Ernest Hemingway.

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).
