Winchester House
Why it's listed
Winchester House is a 160-room Victorian mansion in San Jose, California, built and owned by Sarah L. Winchester, widow of William Wirt Winchester, son of the maker of the Winchester repeating rifle. After the deaths of her daughter and husband, she is said to have consulted a spiritualist medium, moved west and bought an eight-room farmhouse. From 1884 she built continuously, with no master plan, until her death on September 5, 1922. The result is a light wood-frame house with many roofs, brick and concrete foundations, and two basements. Its mixture of shingles, siding, bric-a-brac and cornices shows eastern influence not found in local craftsmanship. The nomination calls it the only example of its type and an outstanding illustration of unchecked Victorian growth. It is also a California Registered Historical Landmark, and an estimated 3,000,000 people have toured it. Restoration of the house and grounds was under way at the time of listing.
Significance in brief: The nomination argues the house is the only one of its type, an outstanding example of Victorian construction that grew without restriction or master plan. It shows an eastern or midwestern Victorian influence in its mix of shingles, siding, bric-a-brac and cornices. It is also a California Registered Historical Landmark (#868) and has drawn an estimated 3,000,000 visitors.

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.
