Air Rights
NYC zoning materials treat "air rights" as a reference to "development rights," i.e., the unused development potential associated with a site under zoning rules. In practice, the term is often used to describe unused floor area that could potentially be shifted or transferred under authorized mechanisms.

In practice
Operators should treat "air rights" as shorthand - actual transferability depends on specific legal mechanisms (merger vs special permit TDR) and district rules.
