An "improvement" is defined as what?

The definition of an "improvement" in the context of real estate refers specifically to a structure that is intended as a permanent attachment to the land. This typically includes buildings, fixtures, and any enhancements made to the property that add value and are intended to remain.

When a structure is classified as a permanent attachment, it usually means that it is integrated into the land or foundation in such a way that it cannot be removed without causing significant damage to either the property itself or the structure. This permanence distinguishes an improvement from temporary structures or movable personal property, which are not considered fixed to the land.

Landscaping features, while they may enhance the property's aesthetic and functional value, can sometimes be less permanent depending on how they are installed and maintained. Thus, the defining characteristic of an improvement is its intention and design for permanent use, which firmly aligns with the correct definition as intended for this question.
