Lot Lines, Encroachments, and Surveys: What Minnesota Property Buyers Need to Know
Buying property in Minnesota — whether it’s a lakeside cabin, rural acreage, or a suburban home — means more than just liking the house or the view. One crucial step that’s often overlooked (until it’s too late) is understanding lot lines, encroachments, and surveys.
These aren’t just technicalities. They can affect your property’s value, your ability to build, and even your relationship with neighbors. Here’s what you need to know to protect your investment.
What Are Lot Lines?
Lot lines define the legal boundaries of your property. Think of them as the invisible fences that separate what’s yours from what belongs to your neighbors or the public.
In Minnesota, lot lines are determined by recorded plats (for platted subdivisions) or legal descriptions in deeds (for unplatted parcels). However, they’re not always visible on the ground — and they’re often misunderstood.
Why it matters:
- You may not own that stretch of land you mow every summer.
- A fence or shed might be partially on your neighbor’s lot — or vice versa.
- You can’t build too close to a lot line without meeting zoning setback rules.
Encroachments: A Hidden Problem
An encroachment occurs when a structure (like a garage, fence, driveway, or even a deck) crosses over a property line onto someone else’s land.
This is more common than you might think — and it can cause major headaches.
Common encroachments in Minnesota include:
- Fences placed over the line due to assumptions or informal agreements.
- Boat lifts or docks partially resting on a neighbor’s lakeshore property.
- Garages or additions built without accurate surveying.
Why it matters:
- Encroachments can lead to legal disputes and even lawsuits.
- Title companies may raise issues or require corrective action before closing.
- You may be forced to move or remove the encroaching structure — at your own cost.
The Importance of a Professional Survey
A professional land survey is the only way to accurately confirm property boundaries and identify any encroachments.
In Minnesota, surveys are typically performed by licensed land surveyors and can include:
- Boundary surveys – show exact lot lines and corners.
- Certificate of survey – often required by cities when applying for permits.
- ALTA/NSPS surveys – detailed commercial surveys often used for title insurance.
When should you get a survey?
- Buying a home or lot — especially if it’s unplatted or in a rural/lake area.
- Building a new structure (garage, deck, addition, fence).
- If you notice anything unclear or inconsistent with the plat map.
- When buying or selling acreage, farmland, or property with natural boundaries.
What to Look For in Minnesota Property Records
Before buying a property, request:
- The plat map (if available) from the county or city website.
- Any existing survey certificates from the seller or title company.
- A review of legal descriptions in the deed and title commitment.
If the property has never been surveyed — or if the survey is outdated (older than 10 years or pre-GPS) — it’s worth ordering a new one before closing.
Final Thoughts: Don’t Skip the Survey
In Minnesota, where lakes, winding rural roads, and old property lines create unique challenges, a survey isn’t just a formality — it’s protection.
Knowing where your lot begins and ends ensures you’re not inheriting someone else’s problem, overstepping your bounds, or risking costly boundary disputes. It gives you the confidence to build, fence, or sell without fear of legal entanglements.
So whether you’re buying your dream lake lot or a starter home in the suburbs, make a professional survey part of your due diligence. It’s a small price for long-term peace of mind.
