What is Air Rights (Development Rights)?
Air rights — more precisely called "unused development rights" — represent the difference between what is built and what is allowed by zoning. In NYC, these rights have significant value, especially in high-density districts.
Air rights can be transferred between adjacent lots through a zoning lot merger, allowing a neighboring building to be built taller than its own lot would allow. In special districts, Transferable Development Rights (TDR) can be moved between non-adjacent lots.
Example: A 2-story building on a lot with FAR 10.0 has significant unused development rights that can be worth millions of dollars in prime Manhattan locations.
