Hazeltine, A. J., House
Also known as: Honorable Charles Warren Stone Museum
Why it's listed
Built between 1905 and 1907 in Warren, Pennsylvania, this three-story brick house was designed by Edward A. Phillips for A. J. Hazeltine, a banker who rose to president of the Warren Savings Bank in 1889. Its free Jacobean treatment includes buff brick, Vermont marble trim, and a red tile roof. The interior features a living room with dark oak paneling and a plaster frieze, a carved dining room, and a barrel-vaulted hall. Hazeltine's heirs sold the house to the American Legion in 1928, which used it for about forty years. Later it passed to a local businessman before the county bought it in 1975 for a museum run by the Warren County Historical Society. The building is regarded as a rare large residence of its type in Warren, and its eclectic blend of classical and English elements is considered both elegant and unusual.
Significance in brief: The nomination argues the house is an excellent example of a large baronial residence in an adaptive Jacobean style, and that it is unique among private dwellings in Warren. Its interiors, including a large paneled living room and carved dining room features, are described as striking, and its scale and proportion are said to unify its eclectic details.

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.
