The New York City Landmarks Preservation Commission (LPC) designates several types of landmarks within the city, each with their own level of protection and preservation requirements. Here are the main types of landmarks designated by the LPC:

• Individual landmarks: These are buildings, structures, or sites that have been designated by the LPC as having significant architectural, historical, or cultural importance. They are protected by the LPC and any changes or alterations to their exteriors or interiors must be reviewed and approved by the commission.

• Interior landmarks: These are spaces within individual landmarked buildings that have been deemed architecturally or historically significant. They may include lobbies, foyers, staircases, or other interior features. Changes to the interior of these spaces must also be reviewed and approved by the LPC.

• Historic districts: These are areas within the city that have been designated by the LPC as having significant architectural or historical character. They may include blocks, streets, or entire neighborhoods. Any changes to the exterior of buildings within a historic district must be reviewed and approved by the LPC.

• Scenic landmarks: These are natural or man-made landscapes that have been deemed important to the city’s scenic beauty or public enjoyment. They may include parks, bridges, or other outdoor spaces. Changes to these areas must also be reviewed and approved by the LPC.

The designation of a property or area as a landmark by the LPC affords it a level of protection under the New York City Landmarks Law, and the commission has the authority to regulate any changes to the exterior or interior of the designated property or area.
