Pest House
Also known as: Potter,Ephraim,House

Why it's listed
Known as the Pest House, this eighteenth-century farmhouse at 153 Fairhaven Road in Concord sits on a triangular lot where Fairhaven Road meets Route 2, screened from traffic by a tall hedge. It is a two-and-a-half-story wood frame house on a low fieldstone foundation, with a symmetrical five-bay facade, six-over-six windows, a central door with sidelights and a simple entablature, and clapboard siding. A rear dormer and a modern one-story addition were added later. The house matters for its part in a 1792 smallpox outbreak. Then called the Ephraim Potter House, it became the town hospital after Sarah Potter fell ill, and patients were treated there by Concord's three doctors. Ten people died, two from inoculation and eight from the disease itself. They were buried in a small cemetery set aside across Route 2 for the outbreak's victims. The house remains a well-preserved reminder of that period in the town's medical history.
Significance in brief: The house is significant for its role in Concord's medical history. In 1792 it served as the local hospital during a smallpox outbreak, with those stricken treated there by the town's three doctors. A small cemetery across Route 2 holds the ten people who died in that outbreak.

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.
