Minnesota does not require a land survey before building a fence. State law does not mandate it, and municipalities generally do not require one as part of a fence permit. But building a fence without knowing the exact property line is a calculated risk. If the fence ends up on a neighbor's land, the cost of moving it, plus any legal fees, typically far exceeds the cost of a survey done upfront.
Minnesota Fence Law: Chapter 344
Minnesota Statutes Chapter 344 governs division fences, which are fences along a shared boundary between two adjacent landowners. The key rules:
- Each landowner is responsible for maintaining one half of a fence along a shared property line.
- If one owner builds a fence and the other benefits from it (by keeping livestock in, for example), the second owner can be required to contribute to the cost.
- Disputes over fence responsibility or cost-sharing can be resolved by the local fence viewers, a process outlined in the statute.
The law assumes both owners know where the property line is. When the line is not clearly marked, disputes over fence placement are common.
When a Survey Is a Good Idea Before Fencing
The Boundary Is Not Monumented
If you cannot find existing iron pins or concrete monuments marking your property corners, the line location is uncertain. Many Minnesota lots, particularly older subdivisions and rural properties, have lost their original monuments over time. A surveyor will locate or set new monuments and mark the line before you dig a single post hole.
The Fence Will Run Close to the Property Line
Most fence contractors place fences slightly inside the property line to avoid exactly this problem. But if you want the fence on or near the actual line, you need the line located accurately first. A 6-inch error in the wrong direction means the fence is on your neighbor's land.
Your Neighbor Has a Different Idea About the Line
If you and your neighbor disagree about where the property boundary runs, a survey settles the question with a certified legal document. A licensed Professional Land Surveyor's work product is admissible in court and carries legal weight that a hand-drawn sketch or a GIS printout does not.
The Property Is Near a Lake or Wetland
Minnesota properties near lakes and wetlands often have irregular boundaries that follow natural features. The ordinary high water level may define part of the boundary, and DNR regulations may limit fence placement in shoreland setback areas. A surveyor familiar with Minnesota DNR rules can identify these constraints before you build.
What Happens Without a Survey
The risk without a survey is encroachment. If a fence is built even a few inches over the property line, Minnesota courts have consistently held that the encroaching owner must remove and relocate the structure at their own expense. Legal fees for a property encroachment dispute in Minnesota can run $5,000 to $20,000 or more if the case reaches court. A boundary survey costs $600 to $1,800.
Do You Need a Fence Permit in Minnesota?
Fence permit requirements in Minnesota are set by individual municipalities, not state law. Most cities require a permit for fences above a certain height, typically 6 or 7 feet. Some cities require a site plan showing the fence location relative to property lines. Check with your city or county planning office before starting construction.
How to Find Your Property Line
If a full boundary survey is not in your budget, there are lower-cost options to get a rough sense of your property line location:
- Look for existing iron pins or concrete monuments at the corners of your lot. These may be visible or just below the surface at the corners.
- Review your county's online parcel viewer for a map of your lot boundaries. These maps are approximate and not legally precise.
- Check your property's recorded plat at the county recorder for lot dimensions and bearings.
None of these methods replace a licensed survey for fence placement near a boundary line. For reliable results, hire a licensed PLS from our Minnesota surveyor directory.
