The Landmark Preservation Commission, better known as the LPC, is in charge of administering the city’s Landmarks Preservation Law (Title 63). Created in 1965 following the destruction of Penn Station, they work to preserve aesthetically and historically important buildings, structures, and other objects that make up the New York City vista.
The LPC consists of 11 Commissioners that are appointed by the Mayor and around 70 Staff Members. These staff members consist of preservationists, researchers, architects, historians, attorneys, archeologists, and administrative employees.
In total, there are around 36,000 landmark properties in New York City they oversee. 141 of those are historic districts and district extensions, 1398 are individual landmarks, 119 are interior landmarks, and 10 are scenic landmarks. In fact, the LPC is the largest municipal preservation agency in the nation!
In most historic buildings, windows were designed to be an integral component of the style, scale, and character of the building. This also includes the window sash, framing, and architectural detail surrounding the windows. Because of this importance, windows are among the most significant features of a landmark building.
As per the LPC, new windows must replicate the historic character of the old ones, regardless of existing conditions. This means that the configuration, operation, details, material, finish, size of openings, sills, and decorative moldings all need to be identical to that of the original.
Building or restoring property in a historic landmark district can be a tricky situation. Installing, replacing or repairing windows in an LPC building should always be carried out by an expert. Our Adler Windows Team can advise you on the best route to take and most suitable permit to apply for.
