Who owns that field past Chillicothe? How many acres is the lot for sale near Bartonville? For anywhere in Peoria County, Illinois, the Peoria County parcel map is where those answers begin.
The sections below cover the map itself, the towns from Chillicothe to Mossville, and the deeds and surveys that settle what the map can't.
Opening the Peoria County parcel map
Start with the Peoria County parcel viewer; it opens in a normal browser with no sign-in. Once parcel lines appear, click any tract near Pekin to see who owns it and how many acres the county records. If the official link ever moves, the Peoria County page on Platbookmapper keeps the current version.
The lay of the land in Peoria County
Start your bearings with Peoria, the county seat, then Chillicothe, Elmwood, Farmington, and Pekin. Peoria County covers about 619 square miles of land; its 2023 population estimate from the Census Bureau was 177,513. With that many people per square mile, the Peoria County parcel layer is crowded with platted lots, and the remaining open tracts stand out quickly.
Who's clicking on Peoria County parcels
- Builders bidding a house on a lot in Bartonville start with the parcel ID and legal description, since permit paperwork usually asks for both.
- If a listing in Bartonville says the yard backs up to open land, the map shows who owns that land.
- Current owners in Peoria County pull their parcel before a tax appeal, a refinance or a talk with the neighbor about a fence.
Acreage and vacant lot search
Five steps for vacant land in Peoria County:
- Scan the imagery around Mossville; open fields and woodlots with no driveway stand out right away.
- For each tract near West Peoria, note the parcel ID, the owner and where the tax bill is mailed.
- Compare the record's land value against similar parcels on the same road out of Pekin.
- Check that the tract touches a public road; a landlocked lot near Pekin can be hard to finance and build on.
- Rural lots near Mossville may need a septic permit and a well, so ask before you commit.
Are the Peoria County property lines accurate?
A lot line on the Peoria County parcel map near Chillicothe is a drawing based on deeds, not a measurement taken on site. Square-ish tracts around Chillicothe are no accident: Illinois land was surveyed into sections, and deeds still describe land that way. A survey is the only document that settles where a Peoria County boundary actually runs.
