Why it's listed

Built around 1860 on Sheridan Road in Winthrop Harbor, this two-story yellow brick house follows a simple front-gabled Italianate form, with a one-story window bay, carved wooden window arches with keystones, and a frame rear wing. Henry I. Paddock, an early settler who registered his land grant in 1850, is believed to have built it, and he kept an inn there as a relay stop on the stage line between Waukegan and Kenosha. Anson E. Lapham bought the property in 1871 and served as the first postmaster of Spring Bluff, later Winthrop Harbor. A sun porch was added in 1884, and Queen Anne details appear in the interior woodwork, plaster and staircase alongside Italianate features such as the walnut-newel stair and arched pocket doors. The house is described as the oldest in the village and is recognized locally for its architecture. It remains a single-family home in excellent condition, with a noncontributing cinder-block garage.

Significance in brief: The nomination argues the house is locally significant under Criterion C as a simple front-gabled Italianate house, with Italianate and Queen Anne interior details from an 1884 remodeling. It is also described as the oldest house in the village. Its frame rear portion is tied to a stage coach inn and relay stop on the Waukegan to Kenosha line.

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.
