Historic Preservation District

Borough of Rocky Hill Historic Preservation District

A significant number of residences in Rocky Hill are located in the Historic Preservation District (HPD). On July 8, 1982, Rocky Hill’s Historic Preservation District was added to the National Register of Historic Places. In addition, the Rocky Hill Historic Preservation District is listed on the New Jersey Register of Historic Places. There are many positive benefits to the designation, including protection from large-scale federal and State projects such as highways, road widenings, bridge replacements, etc. The designation also gives non-profit institutions access to valuable grants for repairs, restorations, and maintenance. It also allows owners of income-producing buildings to receive federal tax credits on the cost of rehabilitation.

The National Register Nomination forms that describe by address within the HPD the architectural history and the style of the dwellings as they existed in 1980 can be viewed below:

Most of the homes on Washington Street are in the HPD. All of the homes on Crescent Avenue, Grove Street, Park Avenue, Reeve Road, Skillman Avenue are in the HPD, while some of the homes on Montgomery Avenue and Princeton Avenue are part of the HPD.

The homes in the HPD are shown in a green shaded overlay on the zoning map located here:

Being in the Historic Preservation District is both a privilege and a responsibility that requires homeowners to seek permission to make changes to the exterior of their property if visible from a public thoroughfare. If you live in the Historic Preservation District and are contemplating renovations, we suggest that you read A Guide to Preservation in Rocky Hill.
