Getting started with the Oswego property search
The Kendall County parcel viewer is the free tool for this; search by address, owner name or parcel ID.
The free map to start with
Lots and tracts near Plano are published on the Kendall County parcel viewer, free to use and open without a login. For a parcel near Aurora, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For property near Yorkville, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
What the map can't tell you
The acreage figure is a tax-roll number; only a licensed surveyor can set the real corners on land around Aurora. For acreage around Montgomery, records update in batches, so a deed recorded last month might lag behind.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Plano sit with the county Recorder of Deeds (in many counties the County Clerk and Recorder). For a home near Yorkville, use the book and page from the tax record so staff can find the deed fast.
Taxes on the record
The record for a parcel near Plattville often lists value and tax amounts; the Supervisor of Assessments, working with township assessors sets values and the treasurer or collector bills taxes.
Offices that can help
Recorded documents for a parcel near Plainfield are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person.
