If you have a specific use in mind for land near Ladue, check the Richmond Heights zoning map first: a district label can make or break the plan. Covered here for Richmond Heights: who controls zoning for a given parcel, how to match a parcel to its district, and what to ask the planning staff.
Getting started with the Richmond Heights zoning map
Within municipal limits, the local government adopts its own zoning map, so property inside Richmond Heights follows that code. Past the city line, around Ladue, county rules apply where they exist; confirm with the county office. The quickest way to tell which applies: ask whether the parcel near Shrewsbury is inside the boundary.
Pulling up a parcel
Begin with the St. Louis County ArcGIS parcel map; it maps each assessed parcel from Maplewood to Shrewsbury. For land near Ladue, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Brentwood, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
What the map can't tell you
Acreage on the record is an estimate; just a licensed surveyor establishes the real lines for a parcel near Shrewsbury. With a lot near Shrewsbury, records update in batches, so a deed recorded last month might lag behind.
City limits and county records
Richmond Heights lies within St. Louis County, Missouri, so its parcels are on the county's map. For acreage around Ladue, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits near Maplewood often falls under county rules rather than the town's.
Offices that can help
For assessment questions about property around Rock Hill go to the County Assessor, the office behind the parcel record. Questions about what you can build around Shrewsbury are for the local planning and health departments, depending on whether the land is inside town limits.
Zoning is only step one
Even when zoning allows a use near Rock Hill, a building permit is a separate step; septic or sewer and driveway access are often reviewed too.
How to look up the district
Start by finding the parcel on the St. Louis County ArcGIS parcel map, copy its parcel ID, and use it when you ask the planning office near Brentwood. For a parcel near Maplewood, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; don't assume a code means the same thing everywhere.
How land is described here
Missouri is laid out under the Public Land Survey System, so rural legal descriptions near Rock Hill cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Ladue odd-sized. Write down the legal description for the tract near Maplewood when you talk to a surveyor.
Setbacks, lot size and uses
For a tract near Brentwood, each district lists what's allowed outright and what needs approval. With a lot near Clayton, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Shrewsbury, though signal can drop in rural spots. A screenshot of the parcel near Rock Hill with its ID helps when you meet an owner or agent.
When a plan doesn't fit
If the land is near Ladue, most of these involve time, so budget weeks or months before you close.
The paper trail behind a parcel
Before you sign anything, pull the recorded deed from the Recorder of Deeds; the parcel line is a drawing of it, and that holds around Shrewsbury too. Older tracts around Clayton can trace back through a long string of deeds, and a title company earns its fee if money is changing hands.
Calling planning staff
When you call about land near Maplewood, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near Rock Hill meets current minimum size, since some older splits don't.
Frequently asked

How do I find the zoning for a lot in Richmond Heights?
It depends, but start with the parcel record, then check the adopted zoning map for Richmond Heights; staff can confirm by phone or email.
Do deed restrictions override zoning near Rock Hill?
