Why it's listed

Standing at 301 Liberty Street in Conneaut, this two-story octagonal house is built of wood frame and topped by a pyramidal roof with an octagonal lantern that lights the central stairwell. Bracketed eaves with pendant knobs, slightly pointed window lintels and vertical board-and-batten walls give it some Italian Villa character. The board-and-batten siding is fairly unusual in northern Ohio, and a north-side porch appears to be a later addition. Each floor has four principal rooms. It was built for David Cummins, born near Buffalo, New York, in 1827, who worked as a harness maker until 1863, when he opened a canning factory that became the D. Cummins Company. He remained active in the business until 1909. The exact construction date is unknown, but the 1860s is most likely. The house is valued as a rare surviving octagon house and as the only building of architectural character in its immediate neighborhood.

Significance in brief: It was built by an important nineteenth-century Conneaut manufacturer and is one of the rare examples of a rapidly disappearing type, the octagon house. Its vertical board-and-batten siding is unusual, especially in northern Ohio.

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.
