What do air rights allow a property owner to do?

Air rights allow a property owner to utilize the vertical space above their property. This means that the owner can construct buildings, extensions, or other structures that occupy this space. In urban areas, air rights are particularly significant as they can be valuable for creating high-rise buildings or other developments that enhance the property's use and can contribute to maximizing its value.

Utilizing air rights can involve various considerations, including zoning regulations and the rights associated with surrounding properties. It's important for property owners wanting to take advantage of these rights to be aware of local laws and regulations that may affect how they can use that vertical airspace.

The other options touch on different aspects of property rights but do not accurately describe the concept of air rights. Building underground structures pertains to ground rights; harvesting crops relates to agricultural land use; and accessing mineral resources is relevant to subsurface rights. None of these properly encompass what air rights specifically permit.
