LPC Launches New and Updated Permit Guidebook and Mapping Tools

New Resources Advance Commission’s Goals to Deliver Improved Efficiency and Accessibility for LPC’s Applicants and Easier Access to Information for All New Yorkers

Updated Permit Guidebook Provides Guidance on New LPC Rules That Make Application Process Easier, Faster; Enhanced Mapping Tools Offer Streamlined Access to Broader Array of Information and Resources about City Landmarks

NEW YORK – Today, the New York City Landmarks Preservation Commission (LPC) announced the launch of several new and updated resources designed to make it faster and easier for users to access key agency information. Today's launch includes an updated Permit Guidebook and two enhanced online mapping tools – the latest in LPC’s ongoing initiatives to deliver improved efficiency and accessibility for LPC’s applicants and easier access to information for all New Yorkers.

“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,” said Landmarks Preservation Commission Chair Sarah Carroll. “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.”

The new resources include an updated LPC Permit Guidebook, which helps applicants file applications that include the correct materials so that the agency can more quickly issue permits. The new version of the guidebook includes helpful guidance on using Portico, LPC’s permit application portal, and incorporates recent rule changes that cover expanded eligibility for staff-level review of solar panel installations and other climate resiliency and sustainability updates, as well as streamlined approvals for outdoor dining structures in historic districts as part of the city’s Dining Out NYC program and other updates to the permit application process.

LPC also added two new and updated mapping tools to its collection of digital mapping resources today:

Discover NYC Landmarks Map: LPC's most popular mapping tool, built on Esri’s ArcGIS platform, has been upgraded with new features and capabilities that make it even easier for users looking for information on a given landmark site or historic district. The new version offers:
- Building-by-building access to the LPC Designation Photo Collection: users can now click on a building footprint for a pop-up info box that provides a direct link to the building’s designation photos. These photos are a new addition to the range of property information and attributes already available through the map’s pop-up info box feature.
- Easy solution for users looking to locate essential site-specific information like Building Identification Numbers (BINs) – unique identifiers assigned to each building citywide (as well as Tax Block and Lot numbers) that are widely used across agencies as part of the permitting process
- New layer displays City Council and Community Districts
- Updated filters that allow users to sort landmark buildings and sites by style, architect/builder and building type or era of construction. Results can be displayed as lists, displayed visually on the map, and exported for ease of use
- Enhanced base map that more clearly displays lot lines, building footprints, and street names
Archaeology Report Finder: This new mapping tool allows users to virtually explore sites where archaeological research has been conducted citywide by clicking on the map to pull up full archaeological reports on each site, with details about the findings uncovered at that site.
