The free map to start with
The official parcel map for this area is the LaSalle County parcel viewer, and no login is needed to use it. If you're looking near Ransom, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward Leonore, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Getting answers from the right desk
Anything recorded against property around Kangley sit in the index kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Building or septic questions for a lot near Wenona need the planning or permitting office, town or county, depending on location.
Backing up the map with records
Before you sign anything, request the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Ransom only summarizes it. For a parcel near Ransom, have ready the book and page shown in the record panel and the lookup takes minutes.
