When a deed near Longtown says lot and block, look up the Perryville plat map it refers to. What this Perryville guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Who keeps the Perryville plat map
For a subdivision near Longtown, look for the plat book reference on the parcel record; use it to request a copy.
Opening the official parcel viewer
Begin with the Perry County CAMAvision map; it includes every tax parcel in the county, Frohna included. With a lot near Altenburg, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Longtown, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Perryville and the county around it
Perryville sits in Perry County, Missouri, so its parcels are on the county's map. Perryville is also the county seat, which puts the Recorder of Deeds close by. For a home near Frohna, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the town limits toward Frohna generally falls under county rules rather than the town's.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements for land near Frohna are filed with the Recorder of Deeds. Older tracts near Longtown can go back through a long string of deeds, and a title company can sort it out if money is changing hands.
How land is described here
Missouri is laid out under the Public Land Survey System, so deeds around Longtown reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Frohna odd-sized. Copy the legal description from the record for the parcel near Longtown before you request a deed or survey.
Recorded plat or GIS layer
