Valley Mill Farm
Also known as: Eddy's Mill; William Helm House; Helm/Eddy House; VDHR No. 034-0108
Why it's listed
Valley Mill Farm lies near the west bank of Abram's Creek, east of Winchester in Frederick County, Virginia. Its centerpiece is a two-story, four-bay Federal-style brick house, built around 1820 by William Helm as the miller's residence. Across Valley Mill Road stands the brick mill, built at about the same time, which was among the more technologically advanced grist and woolen mills in eastern Frederick County. Fire badly damaged the mill in 1864, probably during the Battle of Opequon, and owner William N. Eddy borrowed money to rebuild it. He ran it until about 1875. After 1885 it became a barn, and after 1958 its ground floor served as a veterinary office. The property also holds a tenant house, sheds and two stone ruin sites. It was listed for its Federal architecture and its place in the county's milling economy, with a period of significance of circa 1820 to 1955.
Significance in brief: The nomination argues the property is architecturally significant as a rural example of the Federal style and as an unusual Frederick County brick mill converted to a barn. It is historically significant for its role in the county's early milling economy. The mill was also damaged by fire in 1864, likely during the Battle of Opequon, as it stood in the line of battle.

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.
