Hallock Homestead
Why it's listed
Sound Avenue in Northville, Riverhead, is lined with farmhouses, and one of them, the Hallock Homestead, preserves a complete farm complex on about two and a half acres, the remnant of an original sixty-acre farm. The one-story, five-bay house was probably built around 1765, expanded with a small west room around 1833, and raised to two stories in 1845. Surrounding it are a timber-framed barn, a milk house that began as a shoemaker shop across the road, a shop/wood house and a privy. The Hallock family, early settlers of the area, farmed the land and lived in the house until 1979. Captain Zachariah Hallock's shoemaker account books from 1771 to 1817 survive in a county museum. The property was listed as an intact, representative example of eastern Long Island farm architecture and of the agrarian way of life on the north fork. A preservation organization now owns it and has restored the barn.
Significance in brief: The nomination argues it is one of the oldest surviving farm complexes on Long Island's north fork and a well-preserved, representative example of rural Long Island architecture. It was established by the locally prominent Hallock family, who occupied the house until 1979. The complex is the oldest and best preserved of several Hallock farms in the area and reflects a pattern of land inheritance and agrarian life. The former shoemaker shop is called its most historically significant structure.

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.
Noted as vacant in the nomination. Nomination documents can be decades old; current status may differ. If you are considering buying an empty listed property, read the due-diligence checklist.
