If a legal description for land in Fairmont cites a lot number, the Fairmont plat map is where those numbers come from. What this Fairmont guide covers: where to request a copy, plat versus tax map, and the details that matter to buyers.
Who keeps the Fairmont plat map
For a tract near Sherburn, recorded plats sit with the County Recorder, usually in a plat book or cabinet.
Pulling up a parcel
Go first to the Martin County Beacon site; it covers every assessed parcel in the county, Granada included. For acreage around Granada, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Welcome, write down the parcel ID before closing the panel; each clerk in the county uses it to find the file.
Fairmont, MN: the basics
Fairmont is part of Martin County, Minnesota, and the county assessor maps its lots. Fairmont is also the county seat, which puts the County Recorder close by. Closer to Granada, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the town limits toward Welcome generally falls under county rules, not municipal ones.
How a plat differs from the tax map
The tax map on the Martin County Beacon site is a summary, but the recorded plat is what the deed relies on.
Details on the Fairmont plat map
For a home near Northrop, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Welcome, though signal can drop in rural spots. A saved image of the lot near Truman and its lines keeps working without signal.
A quick look at the area
Fairmont is the county seat, home to the main records offices. Other places on the map include Northrop, Granada, Welcome, and Ceylon, where town lots give way to larger tracts. About 19,657 people live in Martin County (Census Bureau estimate, 2023) spread over about 712 square miles. Martin County was formed in 1857, so old deeds can run back a long way.
Next door to Martin County
Martin County touches Emmet County, IA, Kossuth County, IA, Blue Earth County, Faribault County, and Jackson County; every one of them runs a separate parcel map. A tract near the line by Sherburn can show up across two assessors' files, so check the adjacent map too. Out toward Ceylon, the Platbookmapper state page links every neighboring county map across Minnesota.
Sections, lots and bearings
Minnesota follows the Public Land Survey System, so deeds around Ceylon reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Ceylon can be irregular. Copy the legal description from the record for the parcel near Northrop when you talk to a surveyor.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Ceylon sit with the County Recorder. Older tracts around Welcome may trace back through several deeds, so a title company is worth hiring if money is changing hands.
Online indexes and office visits
Closer to Northrop, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor can set the real boundary on land around Sherburn. For a home near Sherburn, records update in batches, so a deed recorded last month can take weeks to appear.
Getting answers from the right desk
For assessment questions about property around Northrop belong with the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Truman are for the local planning and health departments, town or county, depending on location.
Amended plats
An amended plat may change lots around Granada, so check for later filings; street vacations near Truman show up in the records too.
Metes and bounds instead
Acreage around Granada outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Quick answers
Are old plats online near Welcome?
For property near Northrop, it varies; some offices have scanned older plats and some haven't, including older subdivisions.
What is a replat near Northrop?
Good question; combining or splitting lots near Welcome usually needs a recorded plat change, often with a surveyor's drawing.
How is a plat different from the parcel map near Welcome?
For a tract near Truman, a recorded plat is based on a survey, but the GIS map is not; trust the plat when they differ.
What is a lot and block description for land near Sherburn?
For a parcel near Welcome, lot and block refer to a numbered lot within a block on a recorded subdivision plat; the deed names the subdivision.
What's the tax parcel number used for near Granada?
It's the number the County Assessor uses to track a tract near Granada, and it's on the record panel and tax bills.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
