Trying to size up a property near Clayton? Pulling up the Maplewood GIS map gets you there fast, without paying for a report. What this Maplewood guide covers: where that map lives, the fastest ways to search, and the limits worth knowing.
Getting started with the Maplewood GIS map
If the land is near Brentwood, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer St. Louis County publishes
Begin with the St. Louis County ArcGIS parcel map; it covers each assessed parcel from Webster Groves to Rock Hill. If you're looking near Webster Groves, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Rock Hill, the record panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
A word on accuracy
Acreage on the record is a tax-roll number; just a licensed surveyor establishes the real lines on land around Clayton. With a lot near Richmond Heights, records update in batches, so a deed recorded last month can take weeks to appear.
Maplewood and the county around it
Maplewood lies within St. Louis County, Missouri, and the county assessor maps its lots. For a tract near Webster Groves, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits near Brentwood often follows county rules rather than the town's.
Finding the right lot
Addresses are the easiest route inside Maplewood; for owner searches, try last name first. For a home near Rock Hill, searching by parcel number never misses, and it's printed on tax bills.
Beyond the parcel lines
For land near Shrewsbury, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
A quick look at the area
Clayton is the county seat, home to the main records offices. You'll also find Brentwood, Richmond Heights, and Shrewsbury. Roughly 987,059 people live in St. Louis County (Census Bureau estimate, 2023) across roughly 508 square miles. St. Louis County was organized in 1812, and some chains of title near Shrewsbury are long. Places such as Spanish Lake Park and Babler State Park help you orient on the aerial around Shrewsbury.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements covering ground around Clayton sit with the Recorder of Deeds. For a parcel near Clayton, have ready the instrument number listed on the parcel record to skip a name search.
Neighboring parcel maps
St. Louis County touches Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, and each of those keeps its own parcel map. Acreage along the edge near Shrewsbury can show up in two county records, so open the neighboring map as well. For a tract near Brentwood, the Platbookmapper state page links every bordering county map across Missouri.
