If a legal description for land in Jerseyville cites a lot number, look up the Jerseyville plat map it refers to. This Jerseyville guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Getting started with the Jerseyville plat map
For land around Elsah, look for the plat book reference on the parcel record; that makes the request quick.
Getting to the right map
Begin with the Jersey County ArcGIS parcel map; it maps each assessed parcel in the county, Fieldon included. When a rural tract has no street number, follow US Route 67 on the aerial until the lines appear, then click inside the one you want. For a home near Fieldon, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Land on the county line
Jersey County touches Calhoun County, Greene County, Macoupin County, Madison County, and St. Charles County, MO, and each of those keeps its own parcel map. Ground near Fidelity that runs to the line can be split in two county records, so open the neighboring map as well. In and around Fieldon, our state page links each bordering county map across Illinois.
Jerseyville, IL: the basics
Jerseyville sits in Jersey County, Illinois, which means parcel data comes from the county. As the county seat, Jerseyville hosts the courthouse, handy when you need recorded documents. For a home near Brighton, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the town limits out by Grafton often follows county rules instead.
Two different maps
The tax map on the Jersey County ArcGIS parcel map is a summary, while the recorded plat is the legal document.
A quick look at the area
Jerseyville holds the county offices, home to the main records offices. You'll also find Otterville, Fidelity, Fieldon, and Grafton, each with its own cluster of lots. About 21,091 people live in Jersey County (Census estimate, 2023) on roughly 370 square miles. Jersey County was organized in 1839, so old deeds can run back a long way. Landmarks such as Pere Marquette State Park make handy reference points on the map near Fidelity.
Details on the Jerseyville plat map
In and around Fidelity, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Getting a copy
For land near Fieldon, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
Land outside a subdivision
Acreage around Fidelity outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Brighton.
A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor can set the real boundary for a parcel near Elsah. For a tract near Brighton, records update in batches, so a deed recorded last month might lag behind.
How land is described here
Illinois follows the Public Land Survey System, so deeds around Fieldon reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Fidelity can be irregular. Keep the legal description for land near Otterville before you request a deed or survey.
Recorded documents worth pulling
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 Fieldon only summarizes it. Inherited tracts near Fidelity may trace back through a long string of deeds, so a title company is worth hiring before a purchase.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Elsah, but coverage can be spotty out of town. A printout of the tract near Fidelity helps when you meet an owner or agent.
Replats and vacations
Lots near Otterville can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Fidelity show up in the records too.
Getting answers from the right desk
Recorded documents for a parcel near Fieldon come from the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Questions about what you can build around Fidelity are for the local planning and health departments, town or county, depending on location.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
