Copley, Col. Ira C., Mansion
Also known as: Aurora Performing Arts Center

Why it's listed
Built between 1906 and 1917 to designs by architect Jarvis Hunt, this three-story, L-shaped mansion on West Downer Place in Aurora, Illinois, was the home and social center of Col. Ira C. Copley. Its Roman brick walls are laid in Flemish bond with glazed headers, and a semi-circular Ionic portico rises the full height of the facade. The entrance has slender pilasters, sidelights and an elliptical fanlight, while the interior features a Georgian open-string staircase and Adamesque ceiling and fireplace ornament in carved wood and molded plaster. The design is described as Neo-Classical Revival drawing on the Federal style, with Italian Renaissance and Beaux-Arts touches. Copley built a career in gas and electric utilities, served in the U.S. House of Representatives, and later developed daily newspapers in the Midwest and Southern California. The house later served as offices for the Copley Press, then as a law office and performing arts school, with the exterior largely intact.
Significance in brief: The nomination presents the house as a prime example of early twentieth century Neo-Classical Revival design highlighting the Federal style, with eclectic touches that keep it from being a literal copy. It is also tied to Copley's careers in the utilities industry, Republican politics and as founder of the Copley Press newspaper chain.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
