For any lot around Rock Hill, the Brentwood GIS map shows lines, owner names and parcel numbers. This Brentwood guide covers: where that map lives, how to search it, and the limits worth knowing.
Finding a lot on the Brentwood GIS map
For a parcel near Maplewood, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Pulling up a parcel
Your first stop is the St. Louis County ArcGIS parcel map; it includes each assessed parcel in the county, Richmond Heights included. For land near Richmond Heights, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Webster Groves, the record panel usually lists the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Brentwood and the county around it
Brentwood lies within St. Louis County, Missouri, and the county assessor maps its lots. For a home near Richmond Heights, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits toward Richmond Heights generally answers to county rules instead.
St. Louis County in a few facts
Clayton serves as the county seat, where most land records are kept. Smaller places on the map include Richmond Heights, Rock Hill, and Maplewood, where town lots give way to larger tracts. If the land is near Richmond Heights, about 987,059 people live in St. Louis County (Census Bureau estimate, 2023) spread over some 508 square miles. For property near Webster Groves, st. Louis County dates to 1812, so old deeds can run back a long way. Features like Spanish Lake Park and Babler State Park help you orient on the aerial around Richmond Heights.

Which office to call
Recorded documents for a parcel near Webster Groves come from the Recorder of Deeds, usually searchable by name or document number. Building or septic questions for a lot near Maplewood need the planning or permitting office, depending on whether the land is inside town limits.

Legal descriptions in Missouri
Missouri is laid out under the Public Land Survey System, so deeds around Webster Groves reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Clayton can be irregular. Copy the legal description from the record for the parcel near Richmond Heights for any title or survey request.
Before you lean on the lines
Acreage on the record is an estimate; only a licensed surveyor sets the real corners for a parcel near Webster Groves. On ground around Ladue, records update in batches, so a deed recorded last month can take weeks to appear.
Where the recorded documents are
When the details count, pull the recorded deed through the Recorder of Deeds; the parcel map near Richmond Heights only summarizes it. Older tracts around Ladue may sit on many deeds, so a title company is worth hiring on a real sale.

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.
