Nantucket’s Historic District Commission (HDC) is an elected town board of volunteer citizens charged with overseeing all construction and signage on Nantucket. The HDC was formed in 1955 and was one of the country’s earliest such oversight committees. While the HDC is a regulatory body that reviews all construction projects on the island, it has no oversight regarding historic interiors, historic building methods or our historic trees. Nantucket Preservation Trust (NPT) is a policy and advocacy organization that works to educate the public about the importance of Nantucket’s historic structures. including historic interiors and traditional ways of building. NPT believes there is immense value in preserving the best of every era, from a ’Sconset fish house to a mid-century modern beach house. NPT has oversight of 23 properties where homeowners have voluntarily entered into a historic preservation deed restriction agreement with NPT and the State. Some NPT staff and Board members serve in an advisory capacity to the HDC.
