Bell Mansion

Why it's listed
Set back from the street on a large lot shaded by tall old trees, this brick mansion at 225 Oak Street in Hillsboro was completed in 1883 to designs by Cincinnati architect Henry Bevis. It is a three-story Chateauesque house laid in common bond, with a steeply pitched hipped roof topped by metal cresting, gabled dormers and three corbelled chimneys. Small wooden porches and covered balconies carry Eastlake-style posts, spindles and pendants. A stone dateplate reading 1883 sits above the first-floor windows of the projecting front bay, and the entrance has double wooden doors beneath a stained glass transom. Inside, original woodwork, wainscoting and hardwood floors survive, along with a carved walnut staircase that rises three stories beneath a skylight of colored glass. The house was listed as part of a group of buildings linked to C.S. Bell, a prominent local inventor and manufacturer, and was judged architecturally significant as well. Its roof was recently re-covered, but the original slate color pattern was kept.
Significance in brief: The nomination ties the mansion to C.S. Bell, a prominent local inventor and manufacturer, and describes it as architecturally significant. Its Chateauesque design, Eastlake porch detailing and original interior woodwork and staircase are noted.

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.
