Property Plats and How to Obtain Yours

published: December 3rd, 2020 by in ADT

What is a property plat?

A plat map, also known as a “plat” or “property plat”, is used to show how a tract of surveyed land is divided into lots within a county or municipality. The plat map is drawn to scale and records the land size, boundary locations, nearby streets, and any easements or rights of way. When you purchase a home or property, you will receive a plat map.

Why do I need a plat map?

It is important to locate your property plat because it contains the property divisions to consult when selling or transferring ownership of a property. In addition, it can be useful if there are any questions regarding access to city sewer and water supplies and to double-check other land documents for accuracy.  Lastly, if you have a home improvement project or simply need to know where your property line and easements are, you need a plat map. If you decide to make any non-routine exterior changes to your lot, you will need to include a copy of your plat when you submit a design review application (DRA) to the Architectural Design Trust (ADT) committee.

If I cannot locate my plat, how can I obtain another copy?

If you are unsure of where your property plat is, double-check your settlement documents first. If you still cannot locate your plat, there are a few ways you can obtain another copy.
