Any property that was sold or is for sale in the United States has a deed recorded at a local courthouse. The deed gives a full written description of the property. These records are open to the public. All cities and counties have a land records office where you can find and print a map of the parcel of land. If you own the property, you should have received a copy of the survey when you purchased the property. Many areas also have GIS mapping available online. This mapping website will show you the property lines for almost any area you choose.
Look at the property map and determine which lot is yours by finding the parcel number as recorded in the deed records. Your lot will be shown as something similar to “Parcel 2 - Lot 14”. If the main property was divided at some point in the past you may see a listing for "Parcel 2 - Lot 14A."
Verify that it is the correct parcel by comparing the surrounding street names and locations. If you know the addresses or names of any of your neighbors, use them to verify that it is the correct lot. The property lines will be shown completely drawn out.
Check with your local tax records office. The tax records also will list the property because the office must have the information to assess the amount of property tax each year. The tax records office can provide a plot map, which also will show the property lines.
