Finding your property lines in Minnesota involves checking county parcel records, reviewing your recorded plat, and, when precision matters, hiring a licensed Professional Land Surveyor. Free online tools give you a starting point. For any decision that involves construction, fencing, or a legal dispute, you need a certified survey.
Step 1: Use Your County's Online Parcel Viewer
Most Minnesota counties publish free online GIS parcel viewers that show lot boundaries on a map. These tools are good for understanding your property's general shape and location relative to neighbors and roads. County viewers in Minnesota include:
- Hennepin County - the county's GIS portal covers all 45 municipalities in Hennepin County with parcel boundaries, aerial imagery, and property data
- Ramsey County - Ramsey GIS provides parcel maps for St. Paul, Maplewood, Roseville, and all county municipalities
- Dakota County - the Dakota County interactive map includes parcel boundaries for Eagan, Lakeville, Apple Valley, Burnsville, and all Dakota cities
- Saint Louis County - covers Duluth, Hibbing, Virginia, and the Iron Range region
- Olmsted County - covers Rochester and surrounding areas in southeast Minnesota
- Statewide - the Minnesota Geospatial Commons at gisdata.mn.gov publishes downloadable parcel data for all 87 counties
These maps show approximate boundaries. They are built from recorded plat data but are not field-surveyed, so they can be off by several feet. Do not use them as the sole basis for placing a fence or building foundation.
Step 2: Check Your Recorded Plat at the County Recorder
Your property's recorded plat is the legal document that shows your lot's dimensions and relationship to surrounding lots. It was prepared by a licensed surveyor when the subdivision was originally created and filed with the county recorder.
The plat shows lot width, depth, angles, and the location of easements. County recorders in Minnesota offer plat records through their offices, and many now provide online access. Hennepin and Ramsey counties have fully searchable online plat indexes. For rural counties, you may need to visit the recorder's office in person or call ahead to arrange access.
Step 3: Look for Iron Pins at Your Property Corners
When a subdivision was platted in Minnesota, the surveyor set iron pins at each lot corner. These are typically 5/8-inch steel rebar or 1/2-inch galvanized pipe, driven to grade or just below the surface. In older neighborhoods they may have been disturbed or buried under landscaping.
A metal detector set to find ferrous metals will help you locate buried pins. Check each corner of the lot systematically. If you find pins at all four corners that match the plat dimensions, you have a reliable reference for your boundaries.
If pins are missing or the dimensions do not match, do not guess. Call a licensed surveyor.
Step 4: Review Your Deed
Your property deed contains the legal description of your parcel. For platted property, this is typically a lot and block number referencing the recorded plat. For unplatted property, it may be a metes-and-bounds description with bearings and distances. The legal description in the deed tells you exactly what you own, but translating it into physical location on the ground is the surveyor's job.
Deeds are recorded with the county recorder (abstract property) or the county examiner of titles (Torrens property). Minnesota has both systems, with many metro and lake-area properties on the Torrens system.
Step 5: Use the Minnesota Geospatial Commons
The Minnesota Geospatial Information Office publishes parcel data for all 87 Minnesota counties through the Geospatial Commons at gisdata.mn.gov. This statewide dataset is updated regularly and can be viewed online or downloaded for use in mapping software. It is useful for comparing parcel shapes and general acreage but carries the same precision limitations as county viewers.
When to Hire a Licensed Surveyor
County GIS viewers and recorded plats are starting points. For the following situations, you need a licensed Professional Land Surveyor:
- Building a fence, deck, addition, or outbuilding near a property line
- Resolving a dispute with a neighbor over where the boundary runs
- Splitting a parcel to sell a portion
- Buying a rural or lake property where boundary uncertainty is common
- Applying for a building permit that requires a survey
A licensed surveyor will research county records, locate existing monuments, set new ones if needed, and provide a signed and stamped document that is legally defensible. Find licensed surveyors in your county through our Minnesota directory.
