What term refers to the right to use the airspace above land?

The term that refers to the right to use the airspace above land is "air rights." This concept is particularly significant in real estate and land use law, as it allows landowners to control and utilize the airspace above their property. In many jurisdictions, air rights are considered separate from the rights associated with the land itself, and they can be bought, sold, or leased independently.

Understanding air rights is essential, especially in densely populated urban areas where vertical development, such as high-rise buildings, is common. By having the legal authority to define how airspace can be used, property owners can maximize their property's potential and influence urban development.

The other terms listed, such as air space, land rights, and property rights, while related to the concept of ownership and usage of physical space, do not specifically address the unique legal rights regarding the airspace above a property. In this context, focusing on "air rights" provides clarity about the specific legal rights associated with the air above land.
