Thompson, Cassius Clark, House
Why it's listed
Built in 1876 on a hillside lot at 305 Walnut Street in East Liverpool, this brick house was the home of Cassius Clark Thompson, who was only 25 when he built it. He chose the site for its view of the Ohio River, a block away. The house is a Victorian design with Italianate details, including bracketed cornices, stone sills and lintels, hooded windows and a three-story tower with a mansard roof and wrought-iron railing. Inside are a central hall with a graceful stairway, high ceilings, transoms over every door and an Italian marble mantel. Thompson led the C. C. Thompson Pottery Company, which grew from making Rockingham and yellow ware to cream-colored and semi-porcelain goods, and he is credited with several pottery inventions. The lot also holds an old modeling shop and a cooper shop from the pottery days. The house was listed for its link to the local pottery industry and for its architecture.
Significance in brief: The house is significant for its close connection with the East Liverpool pottery industry and for its architectural merit. It was built by C. C. Thompson, head of the C. C. Thompson Pottery Company, who is credited with several pottery-related inventions. The form calls it the only important old house remaining in the city that is in good condition and still occupied by its owner.

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.
