Geoghegan, Charles, House
Why it's listed
Set on a one and one-half acre lot on Harbor Hill Drive in Huntington Bay, this house was built around 1915 for Charles Geoghegan, described as a locally prominent businessman. It is an eight-bay, two and one-half story residence with clapboard and shingle sheathing, a gable roof, a projecting pedimented gable on the facade, and varied windows including round-arched, bay and tripartite types. A shed-roofed porch on square columns wraps the house and forms an octagonal projection on the south side. Behind it stands the original garage and servants' quarters, which echoes the main house. The property was listed because it represents the large homes built for well-off families on Huntington's north shore between about 1880 and 1920, when the area changed from farmland to a resort and residential community. Many comparable houses were altered or lost their settings, but this one keeps its landscaped grounds, harbor setting and outbuilding, and mixes Queen Anne and Shingle style features.
Significance in brief: The nomination argues the house is a distinguished, intact example of the upper-income single-family homes built along Huntington's north shore during its turn-of-the-century development. It keeps its landscaped setting, harbor view and original servants' quarters/garage. Its design blends Queen Anne and Shingle style features.

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.
