When someone buys a condominium unit, the legal description on the deed describes?

When a buyer purchases a condominium unit, the legal description on the deed often refers to an air lot. This is because each condominium unit is typically described as a specific volume of space in the air rather than just a piece of land. An air lot encompasses the three-dimensional space above the ground, which is defined by specific dimensions, usually in relation to other units in the building and common areas.

This legal description is crucial as it delineates ownership rights and responsibilities, providing clarity on what is included in the purchase. Unlike traditional real estate where a plot of land is described based on boundaries and landmarks, condominiums prioritize the individual unit within the vertical space of the building, which is why air lot is the most accurate term in this context.

The other terms, while relevant in different real estate scenarios, do not accurately capture the unique nature of condominium ownership. A benchmark refers to a fixed point used in surveying, a monument serves as a physical marker to define land boundaries, and a plat is a map that outlines property divisions but is not specific to the volume of air space that a condominium unit occupies.
