The demolition of the original Penn Station, which started in 1963, sparked widespread dialogue about building preservation. Public outcry from the destruction of this structure helped fuel the 1965 Landmarks Law. This created the NYC Landmarks Preservation Commission (LPC).
Stand-alone landmarks and historic districts are designated to preserve areas of distinct character, significance, and “sense of place.” Brooklyn Heights was the first neighborhood in the city to receive historic status, and now there are 141 historic districts throughout the city, with more to come in the future. About 27% of all of Manhattan’s land is within a historic district, versus 4% for the entire city.
Located here is an interactive map that displays historic districts, as well as individual, interior, and scenic landmarks.
Alterations & Repair Work
Any repairs or alterations of the exteriors of these buildings must be approved by the Landmarks Commission. Owners should be aware of the rules and regulations of their building so that they can propose a change that aligns with the guidelines. The LPC’s Enforcement Department makes sure that buildings comply with the law Landmarks Law.
Landmarks must be in good condition. It is illegal for them to be degrading with nothing being done about it. Even if unlawful alterations were completed by a previous owner, it is the responsibility of the current owner to bring it to compliance.
In order to do work on building in a historic district or a stand-alone landmark, a formal application must be submitted to the LPC. Subsequently, applicants must submit a thorough proposal about the kind of work they plan on doing. Historical photos are provided in order to help visualize the original intent. Floor plans, architectural renderings, and written specifications may also be provided.

Here is a document that guides you through the process for common permit applications, such as awnings, rooftop additions, and fire escapes. In addition, the LPC provides technical resources on rules and regulations for a variety of topics including row houses and solar panels.
LPC violations have two grace periods, as the main motive is to get the building back up to compliance.
The violation process for LPC violations are as follows:
- The Enforcement Department sends a Warning Letter if they have learned of a violation. The conditions may be corrected and will not receive a penalty if fixed in time. This grace period is usually 20 business days. If the law was intentionally violated, this step may be skipped.
- A Notice of Violation (NOV) gives another grace period that gives time to correct the
violation prior to a hearing.
- Certificates of Correction allows owners to plead guilty and correct the violation without receiving a fine.
- Environmental Control Board (ECB) hearing is not related to public hearings where one argues their case for what would be appropriate work done. ECB hearings surround whether permits are obtained and technical requirements in the NOV have been satisfied. Fines are as high as $5,000 if you are found guilty or don’t show up.
- If the work is not fixed after an NOV, additional NOVs will continue to be issued, without grace periods. This will lead to mandatory fines.
Stop Work Orders (SWO) are mandates to immediately halt the work in progress on a historical building. There are penalties associated with an SWO if it is not adhered to.
Complaints can be made against a historic building with the LPC, either directly to them or through 311. All complaints are investigated, based on how severe the situation is. The LPC may send someone on a site visit. Historic photos are analyzed and compared with the building at present. If the building is not in compliance, violations may be issued.
Complaint or violation questions can be directed to the Enforcement Department at 212-66907951.
