What is the House Marker Program?
The NPT Marker recognizes island structures, fifty years old or older that have retained their historic character or have been appropriately restored. The structures must also exhibit a well-maintained appearance that contributes to the streetscape.

What is a house marker?
The marker, a wooden plaque in the shape of an elliptical fan, bears the name of the original owner, builder or historical name of the structure and the date of construction. It signifies recognition by the NPT of the structure's historical significance. The word “marker” derives from the 15th century term “to make your mark“ and distinguishes the sign from the informal quarter boards traditionally used by Island.

How do I obtain a marker?
An owner interested in obtaining a marker for their historic structure can contact the NPT office. The NPT staff will be happy to assist with your application. We will research the history of your house in order to determine the date of construction and the original owner or builder. After consulting with you, the marker will be ordered and will be ready for installation in four to six week. The NPT maintains a register of historic house markers, including submitted documentation and photographs.

What are the benefits of the marker program?
The NPT marker informs the public about the age of a structure and its association with prominent individuals, past or present. The presence of a marker also indicates that detailed information about that structure is available in the archives of the Nantucket Historical Association's Research Library.

What does a marker cost?
The cost of a marker, which includes research, installation expenses, and a one-year membership in the Nantucket Preservation Trust at the “Bricks” level, is $750. A deposit of $375 should accompany the application for the marker. Additionally, the assembled documentation will be available in the archives of the Nantucket Historical Association's Research Library.
