Check your deed. Your property lines were established when your neighborhood was developed, whether that’s 10 years or a century ago. The property lines are noted in a few different locations, including in the legal description for the lot, which would be on your property deed, and on a plat map, which is typically available through your local assessor’s office or planning office. A property’s legal description is most easily found on the deed to the property, and there are a few ways the description can be written. It could simply describe the property’s exact location as it exists on the plat map, or it may include specific details with precise measurements that allow you to walk the property lines from a nearby reference point.
Review a plat map. A plat map shows property outlines for an entire neighborhood or area. On a standard residential street, you can expect to see rectangles all about the same size lined up on each side of the street, which signify each privately owned property. Every individual property will be labeled with an identifying number, which is the parcel number assigned when the lots were planned for separate sale and follow surrounding parcel numbers in numerical order. Your deed should note the parcel number, but you can typically find the parcel information if you look up your home through your local assessor’s office, many of which have online databases.
Visit the county recorder’s office or the assessor’s office. Ask what maps are available for public viewing that include your neighborhood and street. Request a copy of any maps that show clear dimensions of your property lines. Use the maps for reference when measuring your property’s total boundary line on each side.
