Ahead of any building plan near Vinita Park, check the Olivette zoning map before anything else: the zoning district can make or break the plan. This Olivette guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and the questions that save a wasted trip.
Getting started with the Olivette zoning map
Inside town or city limits, zoning usually comes from the municipality, so property inside Olivette is governed there. Outside those limits, near Ladue or Overland, the county may have its own zoning, or none at all; confirm with the county office. The quickest way to tell which applies: ask whether the parcel near Vinita Park is inside the boundary.
The viewer St. Louis County publishes
Go first to the St. Louis County ArcGIS parcel map; it includes every assessed parcel from Vinita Park to Hanley Hills. If the land is near Hanley Hills, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Sycamore Hills, write down the parcel ID before closing the panel; each clerk in the county uses it to find the file.
Olivette and the county around it
Olivette is part of St. Louis County, Missouri, which means parcel data comes from the county. For a home near Sycamore Hills, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits near Charlack usually answers to county rules, not municipal ones.

Finding a parcel's zoning district
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 Vinita Park. For acreage around Vinita Park, 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.
Permits after zoning

Reading the ordinance

Limits of the parcel data
Acreage on the record is a tax-roll number; just a licensed surveyor establishes the real boundary for a parcel near Vinita Park. On ground around Ladue, owner names and values update on a schedule, so a deed recorded last month may not show yet.
What to ask before you buy
Have the parcel ID ready and describe the plan for the lot near Ladue; ask what's allowed by right and what needs a permit. Also ask whether the lot near Vinita Park is a legal lot of record, because nonconforming lots can carry limits.
