When a listing near Eldorado mentions a lot number, the Harrisburg plat map is where those numbers come from. What this Harrisburg guide covers: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Tracking down the Harrisburg plat map
For land around Carrier Mills, look for the plat book reference on the parcel record; that makes the request quick.
Getting to the right map
Go first to the Saline County parcel viewer; it includes every tax parcel from Carrier Mills to Muddy. Out toward Muddy, type 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 Eldorado, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Where Harrisburg fits in
Harrisburg sits in Saline County, Illinois, so its parcels are on the county's map. As the county seat, Harrisburg hosts the courthouse, so deeds and plats are filed in town. With a lot near Raleigh, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the city limits toward Galatia usually answers to county rules instead.
Recorded plat or GIS layer
The tax map on the Saline County parcel viewer is a summary, whereas the plat carries surveyed dimensions.
Lots, blocks and easements
For a home near Stonefort, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
A word on accuracy
Acreage on the record is an estimate; only a licensed surveyor sets the real lines on land around Raleigh. In and around Stonefort, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Backing up the map with records
Before you sign anything, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Muddy only summarizes it. Inherited tracts near Stonefort may go back through several deeds, so a title company earns its fee if money is changing hands.
Next door to Saline County
Saline County borders Franklin County, Gallatin County, Hamilton County, Hardin County, and Johnson County, all with their own assessor records. Ground near Muddy that runs to the line may be split across two assessors' files, so look at the adjacent map as well. In and around Raleigh, the Platbookmapper state page links each bordering county map across Illinois.
Reading the legal description
Illinois follows the Public Land Survey System, which means a tract near Stonefort is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Galatia vary in size. Write down the legal description for the tract near Muddy before you request a deed or survey.
Getting a copy
In and around Stonefort, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
Amended plats
An amended plat may change lots around Carrier Mills, search the index for replats of the same subdivision; street vacations near Galatia show up in the records too.
Metes and bounds instead
Rural land near Galatia that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Carrier Mills.
