Property Plats:

What is a property plat?

A plat map, also known as a “plat”, “property plat”, or “house location plan”, is an architectural drawing 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 should receive a plat map along with other various settlement documents.

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.
