Air Rights

Definition

Air rights refer to the right to control, use, or occupy the space above a physical piece of property. These rights are a crucial element in real estate, especially in densely populated urban areas where vertical development is common. Air rights can be leased, sold, or transferred to another party, often independent of the land itself.

Examples

Skyscrapers: Developers in urban centers often purchase air rights to build high-rise buildings that exceed the height limitations imposed by zoning laws.
Bridges over Railroads: A company needing to build a bridge over a railroad may need to purchase air rights from the railroad company.
TDR Transactions: In some cities, property owners can sell their air rights to others, a process known as Transfer of Development Rights (TDR), allowing for higher density construction on adjoining sites.
