Legal Definitions - air right

An air right is a legal concept that grants an individual or entity the exclusive privilege to use, control, or develop the space above a specific piece of land or an existing structure. Essentially, it is the ownership or lease of the vertical space extending upwards from a property, allowing for construction, development, or even the sale of this valuable overhead area.

Here are a few examples to illustrate this concept:

• Imagine a major city where a developer wants to construct a new office tower directly above an existing, active railway line. To do this, the developer would need to acquire the air rights from the entity that owns the land beneath the tracks. This allows them to build a foundation and structure that spans over the railway, utilizing the vertical space without disrupting the trains below. This demonstrates how air rights enable construction in areas where ground-level development is impossible or impractical.

• Consider a historic, low-rise building situated next to a vacant lot in a bustling downtown area. A new developer purchases the vacant lot with plans to build a very tall skyscraper. To ensure their new building can reach its intended height without encroaching on the historic building's space or to maximize their own building's footprint by building over a portion of the smaller structure, the developer might purchase the air rights from the owner of the historic building. This transaction allows the skyscraper to extend into the airspace above the neighboring property, illustrating how air rights can be bought and sold to facilitate large-scale urban development.

• Picture a homeowner whose property offers stunning, unobstructed views of a lake. Their neighbor owns the adjacent lot, which is currently undeveloped. To protect their valuable view from being blocked by a future multi-story building on the neighbor's property, the homeowner might negotiate to purchase the air rights from their neighbor. This agreement would legally restrict the neighbor from building above a certain height, thereby preserving the homeowner's scenic outlook. This example shows that air rights can be used not only for construction but also to prevent development and protect existing amenities.
