Landmark Violations in NYC: What Property Owners Need to Know

In New York City, a Landmark Violation is issued when work is performed on a landmarked property or within a designated historic district without the required approvals from the Landmarks Preservation Commission (LPC), or when work deviates from what LPC permitted.

Tip: Landmark rules apply to exterior features visible from a public way and, in many cases, specified interior features.

Common Triggers

Without LPC Approval

  • Replacing windows/doors with non-matching styles
  • Cleaning or re-pointing façades with improper methods/materials
  • Installing signage, lighting, or awnings
  • Roof work visible from the street (e.g., railings, bulkheads)
  • Removing original architectural elements

Against Permit Conditions

  • Using materials that differ from the approved set
  • Expanding the scope beyond what LPC authorized
  • Not following approved details, colors, or profiles
  • Starting work before the permit is issued

Penalties & Project Impact

Violations can lead to fines, stop-work orders, and costly rework. They frequently delay DOB permits, appraisals, and closings until compliance is documented.

How to Check If You Have One

  • Review prior LPC permits and approvals tied to your address.
  • Search relevant city portals and request records from LPC.
  • Conduct a site walk-through to compare existing conditions with historic documentation.

Step-by-Step Resolution

  1. Stop unapproved work. Stabilize the site to prevent further issues.
  2. Document conditions. Photos, historic images, and measured drawings.
  3. Prepare filings. Apply for the correct LPC authorization (e.g., Certificate of No Effect, Permit for Minor Work).
  4. Perform corrective work. Use approved materials and methods only.
  5. Close out. Request LPC confirmation/Notice of Compliance and align DOB records.
