Where to open the official Buchanan County plat map
Parcels from Dearborn to Sparta are on the IntegrityGIS - Buchanan County, which the county runs on an Integrity GIS parcel viewer. Rural tracts in Buchanan County often have no street address, so try an owner search or simply pan to the area and click.

Behind the map: land records in Buchanan County
Every line on the Buchanan County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. The office title varies by state (register of deeds, recorder, county clerk or clerk of court), so check the Buchanan County government website for the right one. The parcel record often lists a deed book and page or an instrument number, which is how you request a copy of the recorded deed for a tract near Gower.
Towns, terrain and land across Buchanan County
Parcel searches in Buchanan County tend to center on St. Joseph, the county seat, plus Dearborn, De Kalb, Easton, and Gower. The map also labels unincorporated places, Faucett, Frazier, and Halls among them. Buchanan County was created in 1838 and takes its name from James Buchanan. About 82,956 people lived in Buchanan County in 2023, according to Census Bureau estimates, on roughly 408 square miles. Around Easton and Dearborn nearly every click lands on a platted lot, so the few remaining open parcels are easy to pick out.
Who uses the Buchanan County parcel map
Here's who tends to use it in Buchanan County.
- House hunters looking at St. Joseph use the parcel record as a free check on the listing: lot size, legal description and last recorded sale.
- Builders bidding a house on a lot in Dearborn start with the parcel ID and legal description, since permit paperwork usually asks for both.
- Hunters in Buchanan County use the owner names to line up permission well before the season.
Acreage and vacant lot search
Looking for open ground between St. Joseph and Gower? Try this:
- Start on the outskirts of De Kalb, where empty lots are easy to spot between the houses on the aerial layer.
- A tax bill mailed far from Sparta usually means an absentee owner, so note the mailing address on each record.
- Trace the frontage on any tract near Sparta; without it, access depends on a recorded easement.
- Compare the record's land value against similar parcels on the same road out of St. Joseph.
- Last, call the Buchanan County planning or health office about permits, septic and floodplain before you commit.
For a tract near Gower with no road frontage, see how to tell if land is landlocked.
Reading property lines on the Buchanan County plat map
On rural tracts near Sparta, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. Missouri uses the Public Land Survey System, so rural deeds in Buchanan County often describe land by section, township and range, and you can match the call to the grid on the map. For a fence, an addition or a dispute in Buchanan County, budget for a licensed survey; it's the answer a court or a lender will accept.
Two things the map won't tell you
If a tract near De Kalb changed hands recently, the recorded deed is more current than the map. The acreage on a De Kalb record is what the tax roll uses, and a survey can come out different.

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.
