How to Find Your Property Lines: Fast, Easy, and Precise

Think you know where your property ends? You might be surprised. Property lines are the legal boundaries of your land, and they don’t always line up with fences, driveways, or lawns. Before beginning any outdoor projects, such as building a garage, replacing a fence, installing a pool, or enhancing your landscaping, it’s important to take a moment to evaluate your property’s true boundaries. 

This careful assessment ensures that you can savor the improvements you make to your home and yard without inadvertently encroaching on your neighbors’ territory or causing any potential disputes. In this Redfin guide, we’ll explain what property lines are and how to find them accurately — no matter if you live in a townhouse in Seattle, WA, or own five acres in Atlanta, GA.

Quick answer: How do I find my property lines?

The fastest way to find your property lines is to check your plat map, property deed, or previous survey. You can also use GPS apps like LandGlide or Landgrid to view approximate boundaries. For the most accurate results, hire a licensed land surveyor, especially before building or selling.

What are property lines?

Property lines are the official boundaries that define where one parcel of land ends and another begins.  These lines are established by a surveyor during development and recorded by the city, county, or state.. If a property is ever legally split, the new property lines are established in a survey. 

The property line at the front of your house is known as your frontage, the width of your lot along the street. The property lines on the side of your plot are known as sidelines. Local zoning laws often regulate how close you can build to these lines, so knowing exactly where they are is crucial if you’re planning any construction or landscaping.

13 ways to find property lines

To avoid issues with property lines and prevent confrontation with your neighbors, here are 11 easy ways to find property lines. 

1. Use Google Maps to find property lines 

Google Maps can sometimes display property lines, though availability varies by location. While these lines aren’t legally binding, they offer a quick visual reference.

To try it, go to the Google Maps website and enter your exact address in the search bar. Once the map loads, switch to satellite view using the “Layers” button, then zoom in. If available in your area, you’ll see faint gray lines outlining property boundaries. If not, Google may not have access to the necessary data for that location. Keep in mind that this is a rough estimate and shouldn’t be used for legal or construction purposes.

2. Try property line apps

Other GPS apps can provide you with accurate plat maps. LandGlide and Landgrid are two used most commonly by property owners. 

• LandGlide app: Covers more than 95% of U.S. properties, using GPS to display parcel boundaries along with owner and property info. Available on iOS and Android with a free trial and subscription plan.
• Landgrid Map: Provides access to over 149 million property records nationwide, with tools to view ownership data and customize property maps. A paid version offers extra features like bookmarking and survey tools.

3. Hire a licensed land surveyor

The most accurate way to know where your land begins and ends is to hire a surveyor to determine your property lines. The property surveyor will first check county records to understand the history of the lot. Then they will find out about easements, subdivisions, and any other important factors that could affect your land and what you choose to do with it. The cost to hire a licensed land surveyor typically runs between $330 and $670 per survey and depending on the location, size, and property history, it could be up to $1,000 per survey.

4. Review your property deed

Your deed contains the legal description of your land. This may include measurements, boundary lines, and references to landmarks or subdivisions.. You can get a copy of your deed online or from your county recorder’s office for a fee. 

5. Check the metes and bounds survey

Some older deeds use a metes and bounds system, which describes property lines using physical landmarks and compass directions.. This survey can be hard to understand because it often uses landmarks that may no longer exist. For example, the survey may state that a property line extends “fifty meters from the tall maple.” However, that maple tree may no longer be standing. 

6. Read the property line map (plat)

Whether you buy a house or buy land, you may receive a plat map or property line map. If you don’t, you can find it at the county clerk’s office. The plat will give you the exact dimensions of your lot related to other lots on your block. For a property on a residential street, expect to see similarly sized rectangles lined up on each side of the street, showing each privately owned property. Your neighbors may be able to help as well. You can ask them if they have a copy of their plat map, which would show the layout of the neighborhood.

7. Request a copy from your mortgage or title company 

If you finance your home with a mortgage, the lender will typically require a property survey. Your mortgage company should have a copy of this survey from the purchase transaction. The title company will also run a property search and may have a copy of any surveys or property line maps completed for your property. 

8. Contact your local municipality

Many counties and cities keep surveys on file as part of the public record. You can often request a copy of any existing surveys from your county or local municipality. If the county or municipality has completed a survey for your plot of land, they will have a copy. They usually charge a small fee for copies.  

9. Look for survey pins

During construction, builders often use survey pins to mark the plot of land. Look for thin iron bars staked into the ground in the general area you expect your property lines to be. A metal detector can be a helpful tool for your search along the perimeter of your property. You’ll often find survey pins close to a sidewalk or the curb of the property. However, survey pins can be misleading as utility companies, tree-removal companies, and other contractors may have moved them in the course of their work. 

10. Locate property line markers

Locating property line markers is another alternative to finding survey pins. Property line markers can be made of metal, wood, or concrete. For a relatively new home, the property boundary markers might still be in place. If you find survey pins or concrete boundary markers, they are likely to be more accurate, as wooden stakes are more easily moved. Check your plat map to see where to look for property line markers. 

11. Check sidewalks and streetlights

Sidewalks and streetlights can give you a good visual reference if you don’t know how to find property lines. While they are not a perfect reference, installers may have aligned sidewalks or streetlights with the property lines. Start by looking at the lines cut into the sidewalk in front of the house. A contractor may have cut lines to meet up with the edge of the property or used slightly different concrete to separate properties. This method is a good starting point but be sure to use it in conjunction with a survey or plat map to ensure accuracy. 

12. Visit the local zoning department

Your municipality’s zoning department records plats showing land division, and will have maps drawn to scale for your property. Unless your home was built over a hundred years ago, you can ask for a copy of your neighborhood and lot plat for a minimal fee. The zoning department records will give you the exact dimensions of your lot.

13. Measure the property yourself

You could measure your lot by hand. To do this, you’ll need a long measuring tape, a compass, and perhaps an assistant. Retrace the surveyor’s steps by locating the starting point labeled on the plat. This will be the “common point” or POB. Once you find the starting point, use the measuring tape to follow the plat, recording measurements as you go. his method can give you a general idea but should not replace a professional survey.

Why is it important to know the location of your property lines? 

Understanding your property boundaries protects your investment and helps avoid costly mistakes. Here’s why it matters:

• Prevent encroachment issues: Property lines legally define where your land starts and ends. Without knowing them, you might accidentally build a fence, driveway, or shed on your neighbor’s land.
• Avoid disputes with neighbors: Overhanging tree branches, driveways, or even landscaping that crosses the line can lead to conflicts or legal action.
• Ensure safe construction and improvements: Planning to build a garage, pool, or plant a tree? Knowing your exact boundaries and calling 811 before you dig helps prevent damage to underground utilities.
• Support future home sales: Accurate property line documentation -like a plat map or land survey – is helpful during a home sale and can avoid title insurance issues or delays.
• Stay compliant with local rules: Some states require registering new surveys with the county. Keeping updated records ensures you’re covered legally and helps during resale.
• Gain peace of mind: Whether you’re starting a project or selling your home, knowing your boundaries means you’re being a good neighbor, and protecting your property rights.

Final thoughts on property lines

Finding your property lines might seem like a small detail, but it can save you from big problems down the line. Whether you’re starting a backyard project or planning to sell, make sure you’re working within your legal boundaries.
