On June 27, 2025, the Landmarks Preservation Commission announced the release of new and updated resources, including changes to the permit guidebook, the Discover NYC Landmarks Map, and the new Archaeology Report Finder.
The LPC Permit Guidebook was updated to include guidance for Portico, the agency’s permit application portal, and information about recent rule changes regarding staff-level review of solar panel installations and other sustainability updates. The updated guidebook also includes information on streamlined approvals for outdoor dining structures for restaurants located in historic districts.
The Discover NYC Landmarks Map has been upgraded with new features to provide New Yorkers with easier access to information about the city’s landmarks. The updated map includes building-by-building access to the LPC Designation Photo Collection, which allows users to click on the building’s footprint to see a pop-up box with a direct link to the designation photos for each site in addition to the already available property information. The map features new layer displaces for City Council and Community Districts, updated filters to sort by landmarks by style, architect/builder and building type or era of construction. Results can be exported, displayed as lists, or visually on the map. The base map has been updated to show clearer lot lines, building footprints, and street names.
The Archaeology Report Finder is a new mapping tool that allows users to explore sites where archaeological research has been conducted. Users can click on the map to see full archaeological reports with details about what was found at each site.
Landmarks Chair Sarah Carroll stated, “We are excited to introduce new and updated tools that will help landmark property owners, applicants, and the public engage more easily with the Commission, our work, and the city’s rich historic resources. Today’s launch of the guidebook and mapping tools reflects the Commission’s continued commitment to making our agency’s processes more efficient and accessible for all New Yorkers.”
