Accidental Skyline: Maps

The maps above show where new development could occur across New York City.

Take a minute, select your borough, and see what could be coming to your neighborhood. You might be surprised.

Tips on Using the Maps

  • Click on a tax lot (building site) to see more information about available development rights (what can be built on the site or, if lots are combined by a developer, on adjacent lots). Tax lots that have development rights available are colored yellow through red. Lots that are built to their full zoning capacity are shown in gray.
  • Note that other factors, such as historic districts, or a building’s designation as a landmark, may influence what can be built on a site.
  • Click map-visiblelayers on the top right of the map to overlay history districts, subway lines and NYCHA (public housing) developments
  • map-fullscreen toggles full screen mode
  • map-share provides options for embedding or sharing each map

How Transferrable Air Rights Work

Transferable development rights, TDRs or air rights, allow for the transfer of unused development rights to another development site. The transfer of these air rights allows buildings to become taller and bigger than the city zoning code allows.

These maps concern the primary way transferring unused development rights in New York City: zoning lot mergers. Adjacent lots in the city can be assembled and treated as a single zoning lot, or “merged” into one lot to allow development rights to transfer from one site to another. Development on the site is then allowed “as-of-right,” meaning it does not require public or environmental review. more
