Before you buy a lot near Clarkson Valley with a plan in mind, pull up the Chesterfield zoning map before anything else: the zoning district decides setbacks, lot size and uses. Covered here for Chesterfield: which office sets the rules for a lot, how to match a parcel to its district, and what to ask the planning staff.
Getting started with the Chesterfield zoning map
Inside town or city limits, zoning usually comes from the municipality, so property inside Chesterfield answers to that map. Past the city line, around Ellisville, county rules apply where they exist; confirm with the county office. To find out which side of the line a parcel is on: look for a city limits layer in the St. Louis County ArcGIS parcel map.
The free map to start with
Begin with the St. Louis County ArcGIS parcel map; it maps each tax parcel in the county, Clarkson Valley included. In and around Manchester, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Town and Country, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Chesterfield, MO: the basics
Chesterfield is part of St. Louis County, Missouri, and the county assessor maps its lots. Local government in Chesterfield handles matters such as zoning, permits and utilities inside its limits, but the county runs assessment and recording. Lots just outside the town limits out by Manchester often answers to county rules, not municipal ones.
What to ask before you buy
When you call about land near Clarkson Valley, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near Winchester meets current minimum size, because nonconforming lots can carry limits.
Matching a lot to the Chesterfield zoning map
Pull the parcel up on the St. Louis County ArcGIS parcel map, copy its parcel ID, and use it when you ask the planning office near Clarkson Valley. On ground around Ellisville, short codes on the map aren't self-explanatory, so read the ordinance chapter for each; the letters vary from place to place.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Ballwin, but coverage can be spotty out of town. A saved image of the lot near Ballwin and its lines keeps working without signal.
Setbacks, lot size and uses
In and around Winchester, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. For property near Manchester, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Zoning is only step one
Even when zoning allows a use near Manchester, you still need building permits and inspections; septic or sewer and driveway access are often reviewed too.
Asking for an exception
For land near Clarkson Valley, expect an application, a fee, notice to neighbors and a public hearing.
What the map can't tell you
Listed acreage is a tax-roll number; just a licensed surveyor sets the real boundary for a parcel near Town and Country. For a home near Ellisville, records update in batches, so a deed recorded last month can take weeks to appear.

A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Town and Country can be irregular. Copy the legal description from the record for the parcel near Manchester when you talk to a surveyor.
Which office to call
