The Landmarks Preservation Commission (LPC) is the largest municipal preservation agency in the nation. It is responsible for protecting New York City’s architecturally, historically, and culturally significant buildings and sites by granting them landmark or historic district status, and regulating them after designation.
The agency is comprised of a panel of 11 commissioners who are appointed by the Mayor and supported by a staff of approximately 80 preservationists, researchers, architects, historians, attorneys, archaeologists, and administrative employees.
There are more than 36,000 landmark properties in New York City, most of which are located in 141 historic districts and historic district extensions in all five boroughs. The total number of protected sites also includes 1,405 individual landmarks, 120 interior landmarks, and 10 scenic landmarks.
The Commission receives approximately 800 complaints annually. Every complaint is investigated. Complaints may be submitted by calling LPC or by submitting a complaint form.
When a complaint is received, enforcement staff often visits the property to assess and document possible illegal conditions. Staff then reviews historic photographs and relevant records to determine if violations exist. Staff members also investigate reports of buildings in disrepair and may take enforcement action if an owner has failed to maintain his or her landmark in good repair.
The agency also receives complaints through the 311 system and City complaint portal but please consider contacting the LPC Enforcement staff directly for more detailed information.
