Buying a lot in a subdivision near Desloge? Start with the Farmington plat map, as it records the lot layout that deeds refer to. What this town guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers around Bonne Terre.
The Farmington plat map: start here
For land around Bonne Terre, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Where the parcel data lives
The official parcel map for this area is the St. Francois County CAMAvision map, and no login is needed to use it. For acreage around Leadington, 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 Bonne Terre, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real corners for a parcel near Bonne Terre. If you're looking near Leadington, records update in batches, so a deed recorded last month can take weeks to appear.
Legal descriptions in Missouri
Missouri is laid out under the Public Land Survey System, so deeds around Desloge reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Leadwood odd-sized. Keep the legal description for land near Leadwood when you talk to a surveyor.
Where Farmington fits in
Farmington is part of St. Francois County, Missouri, so its parcels are on the county's map. Farmington is also the county seat, handy when you need recorded documents. Out toward Leadington, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the city limits out by Leadwood usually follows county rules instead.
Amended plats
An amended plat may change lots around Bismarck, so check for later filings; street vacations near Park Hills show up in the records too.

Recorded plat or GIS layer

The map is an index, not the title: deeds, plats and easements for land near Bonne Terre are filed with the Recorder of Deeds. For a parcel near Bismarck, bring the instrument number shown in the record panel so staff can find the deed fast.
Lots, blocks and easements
Recorded easements around Park Hills can block a shed or pool; read the notes on the sheet.
Getting answers from the right desk
