Halliock Inn
Why it's listed
Halliock Inn is a shingled wood-frame building on Middle Country Road in the Branch, a tree-shaded remnant of an old crossroads village in Smithtown. It has a two-and-a-half story main block, formed by an early half-house and a west extension, plus a one-and-a-half story rear kitchen wing. Tall, narrow windows and a steep roof give it a distinctive vertical look. Inside are a large kitchen fireplace with a beehive oven and a third-floor room with an arched ceiling. Thomas Halliock was the first owner of record, and the house was enlarged shortly after 1800. For nearly a century it served as a hostelry on the stagecoach route between Brooklyn and eastern Long Island. It hosted town meetings, courts, balls, and Masonic gatherings, and Walt Whitman took meals there while teaching in 1837-1838. It later became a boarding house and, from 1907, a residence. Today it also serves as a museum.
Significance in brief: The inn sat at the crossing of two of Long Island's major 18th century roads and for nearly a century was the center of Smithtown's social and political life. It is also a fine example of 18th century vernacular architecture, one of few left after 20th century commercialization of the island's main roads.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
