How Do I Find My Property Line: 6 Ways to Do It (Updated for 2025)

---

Property lines are more than just invisible boundaries that keep prying feet out. Whether you’re planning home improvements or resolving a neighbor dispute, it’s part of your responsibility to know where your plot of land starts and ends. Here’s how to find property lines.

What Are Property Lines and Why They Matter

Property lines are a type of boundary line. During the original development of your land, professional surveyors identify where “your land” ends and your neighbors begin and mark them using mostly stakes, pins, or monuments. These formal boundaries are recorded in legal documents.

Knowing where to find property lines helps in the following ways:

• Prevents encroachment issues with neighbors, such as building or landscaping on their property.
• Ensures compliance with local zoning regulations.
• Maintains clear ownership rights.
• Makes planning for future home improvements accurately

These six methods will help you identify where your property lines are.

1. Check Your Property Map

A property line map or plat is a drawing of your property outlining the plot’s boundaries and lengths. It also has extra details that give you an idea of the property’s structure, such as elevations, corners or angles. Your plat may also include maps of the surrounding properties in shared property lines.

It’s the easiest method to look up your property line. If you don’t have a copy of your plat, get one from your local assessor’s office.

2. Review the Homeowner’s Deed

Another material to check your property line is the deed of the property. Like the plat, it’s a legal document that describes your land’s boundaries and measurements, including landmarks.

You can use the property deed as a guide to manually locate the corners of the property line. Use a clear and detailed landmark or description as a starting point. For example, if the deed references a row of trees as the right side of your property line, you can use this to trace the rest.

You can use stakes as markers for the property line. You should be able to match the measured lines on the deed with the physical measurements.

3. Hire a Professional Surveyor

If you don’t own a copy of your plat, another option is to hire a surveyor to perform a land survey. They can measure and map your land accurately and mark corners using stakes so you’ll know exactly where your property starts and ends. You can also request them to do other things, such as researching the property’s history if you recently bought a land or home.

Be aware that hiring a qualified land surveyor will cost you. The average cost of an American Land Title Association (ALTA) or mortgage survey ranges from $2,000 to $3,000.

4. Check for an Existing Property Line Survey

If you recently acquired a property, you can find a copy of the complete property line survey in local or country offices and title or mortgage companies.

Contact your county recorder’s or assessor’s office and get a copy of existing property line records for viewing. Sometimes, you’ll get an outdated copy, which needs to be renewed. If you need help getting one, reach out to your mortgage or title companies. You may need to pay a fee to get the record.

5. Look for Property Line Markers

If the property is relatively new, stroll around it as you might get lucky to find property line markers. Look for steel bars, stakes, flags or fences that indicate the corners of the property.

Some markers may be buried, but a metal detector can help locate them. Finding these markers will give you a good guess of the property line, though you must confirm it through a legal record. Before you dig for markers, call 811, the national call-before-you-dig phone number, to ensure you don’t dig into an underground utility line.

6. Find Property Lines Online

There may be an option for you to locate property lines online. Here are some of the convenient ways.

Browse Through County Websites

Some counties have digitized public documents and government records to make them more accessible. Although not all, some sites have uploaded property records on their database.

Visit your county website and browse to find your area. If you can’t find information about property lines, your country might not have completely uploaded the records or the online feature is unavailable. In this case, you must visit your county’s office in person.

Review Privately-Owned Geographical Information System (GIS) Websites

GIS displays data about the earth’s surface, including streets, vegetation and buildings. A detailed GIS, often owned privately, can show more advanced information about city boundaries, sewer and water connections, property lines and outlines of buildings with aerial shots of the locations.

Since this information is private, you can’t find it on government sites. You can start with this list of GIS data sources and go from there.

Use an App

Thanks to technology, you may find your property line using an app. Here are three app options you can download on your phone.

LandGlide is a popular app for this purpose. It’s an app that uses GPS to access over 150 million parcel records in over 3,000 counties. It offers a free trial for the first seven days and a monthly subscription fee of $9.99 afterward.

The Regrid is another tool for looking up property line details. You can use it to access over 156 million land parcel records across the country. You can sign up for free, but if you want more comprehensive information and advanced features, it will cost you $10 per month.

Another excellent recommendation for checking property lines is Property Survey GPS. You can do several things with this app, such as measure, explore or survey your property and lot. It can also give you an idea of how big your lot is, and you can store this information and other measurements in the cloud. It’s easy to use and perfect for people who find using technology intimidating. It’s free to use for one month.

Search on Google Maps

Check if your property line is visible on Google Maps. Go to the maps and enter your exact address. If you’re unable to view it, switch to other methods mentioned above. Despite Google’s advanced features, not all property lines will be detectable through Maps.

Common Pitfalls to Avoid

• Assumptions based on visual cues: Even if you believe you know where your property line is because of a fence or hedge, these markers might not align with legal boundaries. Always verify using official records or professional surveys.
• Ignoring local regulations: Local zoning laws affect where property lines lie and what you can legally build. Check with local authorities if you plan structural additions or significant landscaping changes.
• Over-reliance on technology: Although GPS apps and online maps are useful, their accuracy can vary. Confirm your findings with legal documents and, when in doubt, consult professionals.

Find Property Line Through Various Means

Now that you know where and how to find property lines using diverse methods, you can confidently determine your boundaries next time you’re renovating, planning a garden, landscaping,  or even planning to sell a piece — or all — of your land. You’re better equipped to tackle any project or potential dispute.

Frequently Asked Questions

1. How do I find property lines without a survey?

Start by checking your property deed and the plat map available from your local assessor’s office. Online tools and apps like LandGlide or Google Maps can provide a preliminary idea. However, for precise results, a professional survey is best.

2. Where can I find property line records online?

Many county websites provide digital land records, including property line maps and plats. GIS websites and subscription-based apps such as LandGlide also offer comprehensive data on property boundaries.

3. Why do property line markers sometimes differ from official records?
A: Property line markers on the ground may shift over time or be misplaced during construction. They might not reflect legal boundaries accurately. Always cross-reference with official records or get a professional survey for confirmation.

4. Can I legally set up a fence without knowing my property line?

While you may install a fence based on visible markers, it’s best to verify the boundaries via official records or a survey to prevent encroaching on a neighbor’s property, which can lead to legal issues.

5. What should I do if I suspect my neighbor encroaches on my property?

First, verify your property lines through official documents or a survey. If encroachment is confirmed, have a calm, non-confrontational conversation with your neighbor about the issue. If needed, consult with a real estate attorney about your options, which might include requesting removal of the encroachment, selling that portion of land, or creating an easement.
