With a few exceptions, air rights can only be transferred to contiguous parcels (the two exceptions in Manhattan that I know of are the &quot;Special West Chelsea Air Rights District&quot; and the midtown rezoning around Grand Central).<p>Curious quirk of NYC real estate: as valuable as air rights are, the City has no formal process to track them other than through the building permit process.  There isn&#x27;t an &quot;air rights&quot; database for example.
