Free Plat Map of My Property
You can usually see a free plat map of your property through the county parcel viewer. Here is how to find your lot and what that map cannot prove.

A free plat map of my property starts with the county that taxes the lot, not with a national app. The assessor already maps your parcel. In most counties you can open that map in a browser without an account.
Find your parcel
- Open the Platbookmapper home page and search the county where the property sits.
- Open the official parcel viewer.
- Search the site address first. That is the physical address of the lot, which is not always the mailing address on the tax bill.
- If the address returns nothing, use the parcel number or tax account printed on the bill. Vacant land often has no address in the assessor's file. A new house may not be entered yet. A parcel with several units may carry only one address.
What you are looking at
The shape on the map is the county's parcel polygon. It is good for seeing which lot is yours, who the assessor lists, and how the lot sits against the road. It is not a survey of the corners. Fences, sheds, and tree lines on an aerial photo are clues, not boundary monuments.
If you need the subdivision plat
A parcel viewer and a recorded plat are different documents. After you have the parcel, check the county's recorded-document or plat search for the subdivision name and lot number. That filed drawing is the plat. The viewer is the current tax map.
When you are done, you should be able to name the county, the parcel number, and the subdivision lot if there is one. Platbookmapper is the directory that gets you to that county. The county site is the map.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
