FAQ

Montana property lines, answered.

Yes. This map draws Montana parcel boundaries from the Montana State Library's public statewide parcel layer (all 56 counties) on satellite imagery.

From the Montana State Library, which publishes the layer as a public web service. The map asks that service for the parcels in view each time you move it, so you see the state's current copy rather than a stored one. Montana’s cadastral layer is tied to the Department of Revenue’s property records, which is why it carries owner and appraisal data for every county.

No. Parcel maps are drawn from deeds and tax records for assessment, and lines can be off by several feet or more, especially in rural areas. They are good for finding a property and getting a sense of its shape and size. For a fence, a building setback, or a boundary dispute, hire a licensed land surveyor, whose survey is the legal record.

They are good tools and they cover every county in the country, which is what their subscription pays for. If you only need Montana, the state already publishes the parcel lines for free, and this map simply puts them on satellite imagery you can search.
