Property lines are the borders that tell you exactly where your property begins and ends. They keep one property owner from encroaching on another owner's land or compromising their privacy by building too close to their house.
The plat map is also your best bet to find your property lines online, as your assessor's office may provide plat map snapshots through its website.
How to Find the Property Lines for Your Land Check your deed. Check the official website for the assessor's office in your municipality. If you don't have a copy, and there's nothing available online, visit the county recorder's office or the assessor's office. Last but not least, hire a surveyor.
