LPC approval process for windows in NYC

The process for installing landmark windows in New York City (NYC) involves complying with specific regulations and guidelines set forth by the NYC Landmarks Preservation Commission (LPC). Here is an overview of the typical process:

1. Determine Landmark Status: Determine if your building is located within a designated historic district or if it has individual landmark status. You can check this information on the LPC’s website or by contacting their office.

2. Research LPC Guidelines: Familiarize yourself with the LPC guidelines for window replacement in landmarked buildings. These guidelines outline the requirements and restrictions for window design, materials, dimensions, and installation techniques specific to NYC’s historic districts.

3. Submit Application: Prepare and submit an application to the LPC for approval of the window replacement project. The application should include detailed information about the proposed windows, including drawings, specifications, photographs, and any other relevant documentation. You may need to work with an architect or preserva tion specialist to ensure compliance with LPC guidelines.

4. Review Process: The LPC will review your application and may request additional information or modifications to the window design. The review process aims to ensure that the proposed windows are appropriate for the building’s historic character and the surrounding neighborhood. This step may involve multiple rounds of review and revisions.

5. Receive LPC Approval: Once the LPC approves your window replacement project, you will receive an official Certificate of No Effect (CNE) or a Certificate of Appropriateness (COA), depending on the scope of the project. The COA is required for major window alterations, while the CNE is for minor changes that meet LPC criteria.

6. Window Fabrication: Engage a reputable window manufacturer or restoration specialist experienced in historic window replication. They will fabricate windows that meet the approved design, materials, and dimensions specified by the LPC.

7. Construction Permits: Obtain the necessary permits from the NYC Department of Buildings (DOB) for the installation of the new windows in case you are modifying the existing openings. The DOB will ensure that the installation adheres to building codes and regulations.

8. Window Installation: Hire a qualified contractor experienced in historic window installation to carry out the work. They should follow the approved design and installation techniques specified by the LPC. The contractor should be familiar with protecting the building’s historic fabric during the installation process.

9. LPC Inspections: The LPC may conduct site visits to inspect the window installation at various stages to ensure compliance with the approved plans and LPC guidelines. They may also request additional documentation or clarification during the process.

10. Final Approval: Once the installation is complete and the LPC is satisfied with the results, they will issue a final sign-off or a Certificate of Completion. This confirms that the window replacement project has been successfully executed according to their requirements.

Remember, the process can vary depending on the specific circumstances and requirements of your building. It is crucial to consult directly with the LPC, engage professionals experienced in historic preservation, and closely follow the guidelines and regulations to ensure a smooth and compliant landmark window installation in NYC.
