Ryon, Judge John, House
Also known as: Judge Ira Kilbourne House

Why it's listed
Built about 1840 on Main Street in Lawrenceville, this temple-form house has a front portico supported by four full fluted Ionic columns and a front facade divided into three equal sections by pilasters. Judge John Ryon, who began practising law in Lawrenceville around 1840, is associated with its construction on land once owned by Judge Ira Kilborne, an early settler. The house's design and details follow the published work of Asher Benjamin, including the door and fretwork patterns. It is regarded as one of the best examples of its type in Pennsylvania and the most impressive building in the town. Temple-form houses are rare, and this one stands only a few hundred yards from the New York State line, where the style is more common. The Ryon family owned the property until 1968 and added rear sections that follow the original style but lack its detail. A two-story porch occupies the southwest corner, and the interior plan is symmetrical.
Significance in brief: The document argues the house is one of the best examples of its type in Pennsylvania and the most impressive building in Lawrenceville. Its design and details are drawn from Asher Benjamin's pattern book, and temple-form houses are described as very rare, with this one only a few hundred yards from the New York State line where the style is more common.

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.
