The Bloomington plat map: start here
For a lot in Bloomington, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
Pulling up a parcel
Property in and around Hudson can be looked up on the McLean County ArcGIS parcel map, free to use and open without a login. With a lot near Carlock, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Normal, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
McLean County in a few facts
Bloomington is the county seat, which is where the courthouse records live. Smaller places on the map include Normal, Downs, Towanda, and Hudson. Around 170,441 people live in McLean County (Census Bureau estimate, 2023) spread over roughly 1,183 square miles. McLean County was organized in 1830, and some chains of title near Towanda are long. Landmarks such as Lake Michigan are easy to spot when you zoom out from Carlock.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Normal are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). For a home near Towanda, have ready the document number listed on the parcel record and the lookup takes minutes.
Before you lean on the lines
The acreage figure is a tax-roll number; just a licensed surveyor can set the real corners for a parcel near Hudson. On ground around Carlock, records update in batches, so a deed recorded last month can take weeks to appear.
When a plat changes
Lots near Hudson can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations show up in the records too.
Bloomington, IL: the basics
Bloomington sits in McLean County, Illinois, and the county assessor maps its lots. Bloomington is also the county seat, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. For property near Downs, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the city limits out by Normal usually answers to county rules, not municipal ones.
Land outside a subdivision
Rural land near Heyworth that was never subdivided may have no plat at all; look for a recorded survey for land near Hudson.
Two different maps
The tax map on the McLean County ArcGIS parcel map is a summary, whereas the plat carries surveyed dimensions.
Which office to call
Recorded documents for a parcel near Towanda come from the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Building or septic questions for a lot near Downs are for the local planning and health departments, and the answer depends on jurisdiction.
Reading the legal description
Illinois uses the Public Land Survey System, so deeds around Heyworth reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Towanda odd-sized. Write down the legal description for the tract near Downs for any title or survey request.
Land on the county line
McLean County meets Champaign County, De Witt County, Ford County, Livingston County, and Logan County; every one of them runs a separate parcel map. Acreage along the edge near Heyworth may be split across two assessors' files, so check the neighboring map as well. If you're looking near Normal, our state page lists each bordering county map across Illinois.
