A portion of a building that was built on another's land is referred to as what?

The term used to describe a portion of a building that has been constructed on another person's land is "encroachment." This concept is important in property law, as it refers to a situation where a property owner builds or extends something beyond their property boundaries and onto their neighbor's land. Encroachments can lead to various legal issues, including disputes between property owners and the potential for a court to order the removal of the encroaching structure. The recognition of this term helps property owners understand their rights and responsibilities regarding property boundaries and the potential consequences of infringing upon another's property.

In contrast, accretion refers to the gradual addition of land through natural causes like sediment deposit, while avulsion involves a sudden change in land boundaries, such as during flooding. An easement, on the other hand, is a legal right to use someone else's land for a specific purpose, which is distinct from the notion of construction encroaching on that land.
