About the LANDMARKS (LPC):
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 once they’re designated.
Violations of the Landmarks Law occur when work is done on a landmark property without a permit, when work does not comply with a permit, or when a landmark building is not maintained in a condition of good repair. After investigating a complaint of a potential violation at a landmarked property, LPC sends a warning letter to the owner of the property. Do not ignore this letter, even if the violation predates your ownership or control of the property.
In most cases, a building owner can correct a violation by obtaining a permit from the Commission and performing the work authorized by the permit. Please note that in some cases, the Commission will require that the illegal work be modified, removed, or replaced.
If the Commission does not receive an application to legalize or correct the unauthorized work or condition before a 20 working-day grace period expires, a Notice of Violation (NOV) may be issued. The NOV is a summons to appear before an administrative law judge at the Environmental Control Board. If you do not appear at the hearing or are found guilty, the judge can impose fines up to $5,000.
