The fastest free ways to find your property line are to check your deed and plat map, look up your county’s online GIS parcel viewer, and locate the survey pins at the corners of your lot. For an exact, legally reliable boundary you will need a licensed surveyor, but most homeowners can get a clear picture for free using public records and a metal detector to uncover buried markers.
Knowing exactly where your line falls matters before you build a fence, plant or remove a tree, or settle a disagreement with a neighbor. Below are six free methods, how to find your survey markers safely, and when it is worth paying for a professional survey. If your goal is tree work specifically, see our focused guide on how to find your property line before removing a tree.
How do you find your property line?
To find your property line, start with the documents you already have—your deed and plat map—then cross-check them against your county’s free GIS parcel map and the physical survey pins at your lot corners. These sources together give most homeowners an accurate picture at no cost. A licensed survey is the only legally definitive option.
6 free ways to find your property line
You can usually piece together your boundaries using public records and a little fieldwork. Here is a quick comparison, followed by step-by-step detail on each method.
| Method | Where to get it | Best for |
|---|---|---|
| Property deed | Closing papers or county recorder | Legal description of your lot |
| Plat map | County assessor or recorder | Scaled drawing of lot dimensions |
| County GIS / parcel viewer | County or city website | Quick visual of parcel boundaries |
| Survey pins | Lot corners (buried metal stakes) | Physical corner markers on site |
| Existing survey | Title company or lender file | Detailed boundary measurements |
| Online maps | Google Maps and similar | Rough estimate only |
1. Check your property deed
Your deed contains the legal description of your lot, written either as a metes-and-bounds description (directions and distances) or by reference to a recorded plat. You received a copy at closing, and if you cannot find it, your county recorder or register of deeds keeps the official record—often searchable online for free.
2. Find your plat map
A plat map is a scaled drawing that shows your lot’s exact dimensions and how it sits among neighboring parcels. Plats are filed with the county assessor or recorder and are frequently available online. They are one of the clearest free references for the shape and size of your property.
3. Use your county GIS or parcel viewer
Most counties now publish a free online GIS (Geographic Information System) map. Search for your county name plus “GIS” or “parcel viewer,” enter your address, and the tool will outline your parcel over an aerial photo. These maps are excellent for a quick visual, though the lines are approximate and should not be treated as a legal boundary.
4. Locate the survey pins
Survey pins—also called markers, stakes, or monuments—are metal rods driven into the ground at each corner of a surveyed lot and at any change in the boundary’s direction. They are often buried a few inches below the surface. Finding them gives you the actual corners established by a past survey.
5. Review an existing survey
If your property was surveyed when you bought it, the survey may be in your title or mortgage file. Ask your title company or lender. An existing survey shows measured distances and is far more reliable than an online map.
6. Check online maps (with caution)
Typing your address into Google Maps and zooming in can show a rough outline of your lot, and some map layers display parcel lines. Treat these as estimates only—consumer maps are not survey-grade and can be off by several feet.
How to find buried survey markers
If your corners are not visible, you can often hunt for the markers yourself. The metal rods—commonly rebar capped with plastic—can sit up to about 10 inches below grade. Use a metal detector and sweep the area where two boundaries should meet, working out from the approximate corner shown on your plat. Measure from known reference points on your plat to narrow the search.
Before you dig, call 811. The free national call-before-you-dig service marks buried utilities so you avoid striking a gas, power, or water line. It is free, required in most areas, and protects you from serious injury and costly damage.
When to hire a professional land surveyor
A licensed land surveyor is the only way to establish a legally definitive boundary. Expect to pay roughly $350 to $700 for a typical residential lot, more for large, wooded, or irregular parcels. Hire one when you are building near the line, resolving a boundary dispute, selling or subdividing, or when the records and markers disagree. A stamped survey is also the strongest evidence if a disagreement ever reaches mediation or court.
Why your property line matters for trees and fences
Property lines decide who owns—and who is responsible for—the trees and fences along your boundary. Before you plant, trim, or remove anything, confirm the line so you do not encroach on a neighbor or take action on a tree you do not own. These related guides go deeper:

How to read your deed’s legal description
Two description styles appear on most deeds. A metes-and-bounds description traces the boundary as a series of directions and distances (“N 45 degrees E, 120 feet…”) starting from a fixed point of beginning—common for older or irregular lots. A lot-and-block description simply references your lot and block number on a recorded subdivision plat, which is typical in planned neighborhoods. If the language is hard to follow, your plat map turns those measurements into a picture, and a surveyor can stake the exact corners on the ground.
Common mistakes when locating your property line
- Trusting the fence. Existing fences are often placed inside, outside, or at an angle to the true line and are not reliable boundaries.
- Treating online maps as exact. Aerial parcel overlays can be off by several feet—fine for orientation, not for building or removal decisions.
- Assuming a hedge or tree row marks the line. Landscaping rarely follows the legal boundary.
- Moving or removing a survey pin. Disturbing a marker is illegal in many states and can trigger a dispute.
- Skipping the 811 call before digging for buried markers or fence posts.
What to do if you and a neighbor disagree on the line
Boundary disagreements are common and usually solvable without a lawsuit. Start with a friendly conversation and share the records you have. If you still disagree, a licensed survey settles most disputes by establishing the legal line. When a neighbor’s structure, fence, or tree crosses onto your land, a written encroachment letter documents the issue and often resolves it. For tree-specific conflicts, our guide on resolving tree disputes with neighbors covers your options before things escalate.
Frequently asked questions
Are property lines public record?
Yes. Deeds, plats, and parcel maps are public records kept by your county recorder or assessor, and most can be viewed for free online or in person.
Can I find my property line on Google Maps?
You can see a rough outline, and some layers show parcel lines, but consumer maps are estimates only. Use them as a starting point, not a legal boundary.
How accurate are county GIS maps?
GIS parcel maps are great for a general picture but are not survey-grade; lines can be off by several feet. For anything legally important, rely on a licensed survey.
Who owns a tree on the property line?
A tree whose trunk straddles the boundary is generally owned jointly by both neighbors, and neither can remove it without the other’s consent. See our guide on handling encroachment with a neighbor.
How much does a property survey cost?
A residential boundary survey typically runs $350 to $700, with larger or heavily wooded lots costing more because they take longer to measure and mark.
How long are survey pins good for?
Survey markers do not expire—the corners they mark remain valid unless the land is re-surveyed and re-monumented. They can, however, be moved, paved over, or lost, so verify against your plat if a pin seems out of place.
Can I put a fence on my property line?
You can generally build up to your line, but local setback rules and any homeowners association requirements may push it inward, and it is wise to confirm the exact boundary first. Building over the line can force costly removal later.

Rules and record-access vary by county and state—confirm your boundary with your local records office or a professional surveyor before taking action.
