Finding a lot on the Farmington GIS map
Parcel maps here are usually run by the county, not the town, which makes the St. Francois County CAMAvision map the main source for lots in Farmington.
Where the parcel data lives
Go first to the St. Francois County CAMAvision map; it covers each tax parcel around Leadwood and Bonne Terre. For acreage around Leadwood, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Leadington, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Reading the legal description
Missouri is laid out under the Public Land Survey System, so rural legal descriptions near Leadington cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Bonne Terre vary in size. Keep the legal description for land near Leadington before you request a deed or survey.
Farmington, MO: the basics
The town is part of St. Francois County, Missouri, and the county assessor maps its lots, especially near Leadington. As the county seat, Farmington hosts the courthouse, so deeds and plats are filed in town. Closer to Bonne Terre, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Leadwood often falls under county rules, not municipal ones.
Finding the right lot
For a house in Farmington, search the street address; owner search often wants the surname first. In and around Bismarck, searching by parcel number never misses, and it carries over to every office in the county.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Leadington, but coverage can be spotty out of town. A screenshot of the parcel near Leadwood with its ID keeps working without signal.
When a parcel crosses a boundary
St. Francois County borders Iron County, Jefferson County, Madison County, Perry County, and Ste. Genevieve County; every one of them runs a separate parcel map. Ground near Leadington that runs to the line may show up in two county records, so look at the adjacent map before you assume the acreage. On ground around Bismarck, the Platbookmapper state page lists every bordering county map for Missouri.
Aerials, labels and overlays
Around Leadwood, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
Owner, value and acreage
Recent sales on nearby lots in this town give a rough idea of values; they're not an appraisal, especially near Bismarck.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Desloge sit with the Recorder of Deeds. Long-held tracts around Leadington may go back through many deeds, and a title company earns its fee if money is changing hands.
What the map can't tell you
Acreage on the record is an assessed number; only a licensed surveyor establishes the real corners for a parcel near Bismarck. For a tract near Bonne Terre, records update in batches, so a deed recorded last month can take weeks to appear.
Saving what you find
Save a screenshot of the lot near Leadwood and its record panel, so you have it when calling an office.
A quick look at the area

Browser tips
If the viewer stalls on a phone near Desloge, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.

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.
