The Jennings plat map: start here
For a lot in Jennings, the deed usually cites the plat; bring that to the recorder's office or its online index.
Getting to the right map
Begin with the St. Louis County ArcGIS parcel map; it covers every tax parcel from Norwood Court to Flordell Hills. Closer to Country Club Hills, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Moline Acres, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Field tips
Most viewers work in a phone browser, useful out on a road near Northwoods, though signal can drop in rural spots. A saved image of the lot near Country Club Hills and its lines is a good backup.
Jennings and the county around it
Jennings is part of St. Louis County, Missouri, which means parcel data comes from the county. For a home near Flordell Hills, 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. Acreage past the town limits toward Flordell Hills often follows county rules instead.
When a plat changes
An amended plat may change lots around Norwood Court, so check for later filings; street vacations near Flordell Hills show up in the records too.
Recorded plat or GIS layer
If the tax map and plat differ near Pasadena Hills, trust the recorded documents over the GIS layer.
When there's no plat
Acreage around Pasadena Hills outside a subdivision may have no plat at all; look for a recorded survey for land there.
Lots, blocks and easements
Recorded easements around Country Club Hills stay with the land when it sells; check the plat notes and any covenants.
Online indexes and office visits
With a lot near Pasadena Hills, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
Next door to St. Louis County
St. Louis County meets Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, all with their own assessor records. Ground near Norwood Court that runs to the line can show up across two assessors' files, so open the adjacent map as well. Around Norwood Court, the Platbookmapper state page links every bordering county map for Missouri.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Country Club Hills sit with the Recorder of Deeds. Long-held tracts near Northwoods may trace back through a long string of deeds, so a title company is worth hiring if money is changing hands.

What the map can't tell you
