Knapp House
Why it's listed
Built around 1905 at 10 Rock Street in the Village of Newark Valley, this two-story frame house was designed as both a family home and a doctor's practice. Dr. Hiram L. Knapp, Sr., had a waiting room and examining office placed in the house, reached through a side entrance, and he practiced there from 1905 until his death in 1942. Cephas Barker of Syracuse is credited as builder. The hipped-roof house shows Colonial Revival features including pedimented dormers, a symmetrical facade, a full-width front porch with a pedimented entrance, wide projecting eaves and clapboard siding. Inside, the center hall plan, staircase, moldings, paneled doors, mantelpieces and oak floors remain. The 1.1-acre lot is unusually large for a neighborhood of mostly nineteenth-century homes and includes an original gambrel-roofed carriage barn and a chicken coop. A gazebo moved from Whig Street is noncontributing. The house is considered the only turn-of-the-century Colonial Revival residence in the village and retains a high degree of integrity.
Significance in brief: The house is significant under Criterion C as a fine domestic example of Colonial Revival architecture that retains a high degree of integrity. It is described as the only turn-of-the-century Colonial Revival residence in the village. It also reflects the village's development context and was built with a medical office and side entrance for its physician 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.
