Buying a lot in a subdivision near Sunset Hills? Start with the Crestwood plat map, as it records the lot layout that deeds refer to. What this Crestwood guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Tracking down the Crestwood plat map
For a lot in Crestwood, look for the plat book reference on the parcel record; that makes the request quick.
Getting to the right map
Go first to the St. Louis County ArcGIS parcel map; it maps every tax parcel from Grantwood Village to Sunset Hills. Closer to Marlborough, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. If you're looking near Grantwood Village, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Where Crestwood fits in
Crestwood sits in St. Louis County, Missouri, so its parcels are on the county's map. If you're looking near Marlborough, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the town limits out by Oakland generally answers to county rules, not municipal ones.
Replats and vacations
Lots near Grantwood Village can be combined or reconfigured by a replat, so check for later filings; street vacations near Lakeshire show up in the records too.
Places you'll see on the map
Clayton is the county seat, which is where the courthouse records live. You'll also find Grantwood Village, Oakland, Marlborough, and Webster Groves, each with its own cluster of lots. Roughly 987,059 people call St. Louis County home (Census estimate, 2023) on some 508 square miles. St. Louis County dates to 1812, and some chains of title near Lakeshire are long. Features like Spanish Lake Park and Babler State Park make handy reference points on the map near Webster Groves.
Neighboring parcel maps
St. Louis County meets Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, and each of those keeps its own parcel map. Ground near Lakeshire that runs to the line may be split in two county records, so look at the adjacent map too. For acreage around Webster Groves, the Platbookmapper state page links each bordering county map for Missouri.
What the map can't tell you
Listed acreage is an estimate; only a licensed surveyor establishes the real lines for a parcel near Webster Groves. Around Sunset Hills, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Metes and bounds instead
Acreage around Marlborough outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Webster Groves.
Plat map vs. parcel map
When the two disagree for a lot near Marlborough, go with the plat and a surveyor's work.
What a plat shows
Utility or drainage strips on a lot in Crestwood stay with the land when it sells; check the plat notes and any covenants.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Grantwood Village are kept by the Recorder of Deeds. Long-held tracts around Oakland may sit on a long string of deeds, and a title company can sort it out if money is changing hands.
Legal descriptions in Missouri
Missouri is laid out under the Public Land Survey System, so rural legal descriptions near Grantwood Village cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Lakeshire odd-sized. Write down the legal description for the tract near Sunset Hills when you talk to a surveyor.
Which office to call
Anything recorded against property around Grantwood Village come from the Recorder of Deeds, sometimes only in person. Questions about what you can build around Webster Groves need the planning or permitting office, depending on whether the land is inside town limits.
Requesting the plat
For property near Oakland, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Sunset Hills, but coverage can be spotty out of town. A screenshot of the parcel near Marlborough with its ID keeps working without signal.

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.
