If you have a specific use in mind for land near Huntleigh, look at the Ladue zoning map before anything else: the zoning district can make or break the plan. Covered here for Ladue: who controls zoning for a given parcel, matching a lot to its zoning district, and when a variance or rezoning comes up.
The Ladue zoning map: start here
Within municipal limits, zoning usually comes from the municipality, so property inside Ladue answers to that map. Past the city line, around Olivette, the county may have its own zoning, or none at all; the county planning or zoning office can confirm. A fast way to settle it: ask whether the parcel near Huntleigh is inside the boundary.
Pulling up a parcel
Go first to the St. Louis County ArcGIS parcel map; it covers each assessed parcel from Huntleigh to Rock Hill. If the land is near Huntleigh, put in 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 Frontenac, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
A word on accuracy
Listed acreage is an assessed number; just a licensed surveyor establishes the real corners on land around Frontenac. Around Olivette, records update in batches, so a deed recorded last month might lag behind.
Who handles what
Deeds, mortgages and recorded plats for land near Olivette are with the Recorder of Deeds, usually searchable by name or document number. Building or septic questions for a lot near Olivette are for the local planning and health departments, and the answer depends on jurisdiction.
Sections, lots and bearings
Missouri is laid out under the Public Land Survey System, so rural legal descriptions near Olivette cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Huntleigh odd-sized. Write down the legal description for the tract near Olivette before you request a deed or survey.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Warson Woods, so load it before you lose signal. A saved image of the lot near Olivette and its lines helps when you meet an owner or agent.

City limits and county records

On ground around Brentwood, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits toward Warson Woods generally falls under county rules instead.
What to ask before you buy
When you call about land near Warson Woods, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Also ask whether the lot near Olivette is a legal lot of record, since some older splits don't.
Reading the district label
Look up the lot on the St. Louis County ArcGIS parcel map first, note the parcel number, then compare it to the zoning map from the office covering Ladue. Closer to Olivette, short codes on the map point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.
What the district controls
For a tract near Rock Hill, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. Closer to Huntleigh, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
Building permits and inspections
Even when zoning allows a use near Huntleigh, a building permit is a separate step; health and road departments may weigh in on land near Olivette.
Changing what's allowed
For acreage around Frontenac, most of these involve time, so budget weeks or months before you close.
