Hopkinson, George, House
Why it's listed
Built around 1716 on Main Street in Groveland, this two-and-a-half story house began as a single-cell, First Period dwelling one bay deep. In the 18th century a rear lean-to and a long, narrow, one-and-a-half story side ell were added. During the Federal period the lean-to was raised, the chimney remodeled and a new roof built, and the front door and windows received Federal surrounds with splayed lintels. Most of the original plank frame lies behind later boxing and plaster. Evidence of plank construction includes mortises in the exposed rear girt for two-inch planks, chamfered summer beam with cove stops in a second-floor closet, and old planks reused in the cellar stair partition. The house was listed for its architecture because it keeps its original single-cell facade, a type once common but now almost vanished in Massachusetts. It is also valued for the information its plank frame, an uncommon technique in the region, may hold. It remains a single-family residence.
Significance in brief: The house keeps its original single-cell front facade and First Period plank frame, which makes it a rare survivor of a once-common house type in Massachusetts. Plank framing is an uncommon alternative in Massachusetts Bay, and the hidden frame may yield information about late First Period framing and decoration.

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.
