Landmark Permit Services

An NYC Landmark permit is an approval issued by the New York City Landmarks Preservation Commission (LPC) for work performed on designated landmark buildings or properties located within historic districts. Depending on the project, approval may be required before repairing, replacing, restoring, or altering windows, doors, storefronts, façades, and other exterior architectural features.

You may need LPC approval if your property is an individual landmark or located within a designated NYC historic district. Work involving historic windows, doors, storefronts, exterior materials, masonry, signage, or façade details often requires a Landmark permit before construction begins.

Our team evaluates each project individually, explains the applicable requirements, and provides a clear path toward approval.

Yes. We assist homeowners, developers, property managers, and business owners with correcting and removing NYC Landmarks violations. We review the cited violation, determine what corrective work or documentation is required, and help guide the project through the approval and compliance process.

• Historic window restoration and replacement
• Custom door restoration and replacement
• Storefront and façade renovations

During the consultation, we assess the property and proposed scope of work, review potential Landmark requirements, identify any existing compliance issues, and outline the recommended next steps.

Every project is evaluated individually to ensure the application reflects the building’s historic character and the specific requirements of the NYC Landmarks Preservation Commission.

Required documents vary depending on the project but may include photographs of existing conditions, architectural drawings, product specifications, material samples, window or door details, and a written description of the proposed work.
