Walper, Capt. Henry, House

Why it's listed
Built in 1899 at the southwest corner of South and Exchange Streets in Vermilion, Ohio, this two-story Queen Anne house was constructed for Captain Henry Walper, a prominent Great Lakes ship captain. The wood-frame building rests on a sandstone foundation and is topped by a hipped gable roof of slate, ornamented with finials. Its irregular plan produces an interesting mass of projecting wings, bay windows and porches. Other distinguishing features include a wide cornice, pilasters, horizontal fascia boards and simple plain window moulding. Inside, oak parquet floors and stairways stand out. The house sits on a small corner lot with a garage at the south end, open lawns and a picket fence along the west property line. It remains a residence in good to excellent condition, and its connection to a ship captain makes it an important link with the maritime history of Vermilion.
Significance in brief: The house was built for Captain Henry Walper, a prominent Great Lakes ship captain. The inventory describes it as an important link with the maritime-oriented history of Vermilion. It is also a well-preserved example of Queen Anne design with distinctive roof and trim details.

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.
