Trying to understand lot lines near Maplewood? Start with the Brentwood plat map, since it shows lots, streets and easements as approved. What this Brentwood guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Brentwood plat map
For land around Maplewood, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Where the parcel data lives
Go first to the St. Louis County ArcGIS parcel map; it includes each assessed parcel from Maplewood to Rock Hill. Out toward Clayton, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Rock Hill, the parcel card usually lists the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Maplewood, but coverage can be spotty out of town. A printout of the tract near Richmond Heights keeps working without signal.
How land is described here
Missouri uses the Public Land Survey System, which means a tract near Clayton is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Webster Groves can be irregular. Write down the legal description for the tract near Ladue for any title or survey request.
Where Brentwood fits in
Brentwood lies within St. Louis County, Missouri, which means parcel data comes from the county. For a parcel near Ladue, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits out by Ladue often follows county rules, not municipal ones.
St. Louis County in a few facts
Clayton holds the county offices, home to the main records offices. Other places on the map include Richmond Heights, Rock Hill, and Maplewood, each with its own cluster of lots. If you're looking near Rock Hill, around 987,059 people live in St. Louis County (Census Bureau estimate, 2023) on some 508 square miles. St. Louis County was organized in 1812, and some chains of title near Clayton are long. Landmarks such as Spanish Lake Park and Babler State Park are easy to spot when you zoom out from Richmond Heights.
Who handles what
Questions about value or the owner field for land near Richmond Heights are handled by the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Richmond Heights go to planning, building or health offices, depending on whether the land is inside town limits.
Land outside a subdivision
Acreage around Rock Hill outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land there.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements for land near Maplewood are kept by the Recorder of Deeds. Inherited tracts near Rock Hill may trace back through many deeds, so a title company earns its fee on a real sale.
Plat map vs. parcel map
When the two disagree for a lot near Maplewood, the recorded plat and a survey control.
Land on the county line
For property near Maplewood, st. Louis County meets Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County; every one of them runs a separate parcel map. Acreage along the edge near Richmond Heights may show up in two county records, so open the adjacent map too. For property near Richmond Heights, our state page links every neighboring county map across Missouri.
Amended plats
Lots near Clayton can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Ladue show up in the records too.
Details on the Brentwood plat map
Recorded easements around Webster Groves can block a shed or pool; read the notes on the sheet.
What the map can't tell you
Listed acreage is an assessed number; only a licensed surveyor establishes the real lines for a parcel near Ladue. Owner names and values update on a schedule, so a fresh transfer around Richmond Heights can take weeks to appear.
Ordering the Brentwood plat map
For a parcel near Ladue, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.

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.
