Which term refers to the legal permission to use a specific piece of land for particular purposes?

The term that refers to the legal permission to use a specific piece of land for particular purposes is zoning designation. Zoning designations establish the allowed uses for a property and dictate how land can be developed or utilized. These designations play a crucial role in urban planning, ensuring that land is used in a manner that is consistent with the overall guidelines and regulations set forth by local governments.

Zoning amendments, while related to changes in zoning designations, specifically refer to modifications or updates to existing zoning laws. Zoning codes are comprehensive sets of regulations that govern land use but do not directly reference permission to use a specific piece of land. Zoning classifications further categorize zoning designations into more detailed segments but do not stand alone as the legal permission itself. Hence, zoning designation is the most accurate term for the legal permission regarding land use.
