Tracking down the Bozeman plat map
For a lot in Bozeman, the deed usually cites the plat; bring that to the recorder's office or its online index.
Where the parcel data lives
Begin with the Gallatin County parcel viewer; it includes every tax parcel in the county, Belgrade included. When a rural tract has no street number, pan along the nearest road and click the parcel itself, which applies near Belgrade as much as anywhere. For acreage around Manhattan, write down the parcel ID before closing the panel; every clerk in the county uses it to find the file.
Places you'll see on the map
The city serves as the county seat, where most land records are kept, especially near Belgrade. You'll also find Belgrade, Manhattan, Three Forks, and West Yellowstone, each with its own cluster of lots. About 126,409 people call Gallatin County home (Census estimate, 2023) on about 2,605 square miles. Gallatin County dates to 1865, so old deeds can run back a long way. Places such as Yellowstone National Park help you orient on the aerial around Belgrade.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Three Forks, though signal can drop in rural spots. A printout of the tract near Belgrade is a good backup.
Getting answers from the right desk
For assessment questions about property around West Yellowstone belong with the Montana Department of Revenue, the office behind the parcel record. Questions about what you can build around Belgrade need the planning or permitting office, and the answer depends on jurisdiction.
Where Bozeman fits in
Bozeman lies within Gallatin County, Montana, so its parcels are on the county's map. As the county seat, Bozeman hosts the courthouse, so deeds and plats are filed in town. For acreage around Three Forks, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits toward Belgrade often answers to county rules, not municipal ones.
Legal descriptions in Montana
Montana uses the Public Land Survey System, which means a tract near Three Forks is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Belgrade vary in size. Keep the legal description for land near Belgrade before you request a deed or survey.
How a plat differs from the tax map
The Gallatin County parcel viewer draws parcels for taxes, while the recorded plat is the legal document.
Amended plats
An amended plat may change lots around Three Forks, so check for later filings; street vacations near West Yellowstone show up in the records too.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Three Forks are filed with the County Clerk and Recorder. Older tracts around West Yellowstone may go back through a long string of deeds, so a title company is worth hiring before a purchase.
What a plat shows
Utility or drainage strips on a lot in the city limit where you can build or fence; read the notes on the sheet, especially near West Yellowstone.
What the map can't tell you
Acreage on the record is a tax-roll number; just a licensed surveyor sets the real corners on land around Belgrade. Records update in batches, so a recent sale near Belgrade may not show yet.
Getting a copy
For a home near Three Forks, some counties put plat images online, while others require a visit or a request; small fees are common.
Land outside a subdivision
Acreage around West Yellowstone outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
