What is a plat map?

A plat map is indeed best defined as a subdivision map showing blocks of land. It provides a detailed layout of a specific piece of land that has been divided into individual lots or parcels. This document typically includes important information such as the boundaries of each lot, the layout of streets and easements, and other relevant features. Plat maps are essential for urban planning, property development, and real estate transactions because they help buyers and developers understand how land is divided and used.

The detailed property survey, while related, serves a different purpose and tends to focus more on the precise measurements and boundaries of individual properties rather than the broader subdivision layout. A zoning district outline, on the other hand, indicates how land in specific areas can be utilized (like residential, commercial, or industrial) but does not provide the detailed local planning information that a plat map does. Similarly, a type of building permit relates to the authorization required to construct or modify a building, which is not what a plat map represents. Thus, the definition that states a plat map is a subdivision map showing blocks of land accurately captures its intended use and significance in real estate.
