The official viewer behind the Montgomery GIS map
In most places the county maintains the parcel layer, so for Montgomery the go-to is the Kendall County parcel viewer.
The free map to start with
Begin with the Kendall County parcel viewer; it covers each assessed parcel in the county, Plano included. For a home near Aurora, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Millbrook, write down the parcel ID while you have it open; each clerk in the county will want it.
City limits and county records
Montgomery sits in Kendall County, Illinois, and the county assessor maps its lots. With a lot near Oswego, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits out by Oswego often follows county rules rather than the town's.
Which office to call
Anything recorded against property around Millbrook are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), often with an online index. Building or septic questions for a lot near Plano need the planning or permitting office, and the answer depends on jurisdiction.
Searching the map
For a house in Montgomery, search the street address; owner search often wants the surname first. For a home near Yorkville, searching by parcel number never misses, and it's printed on tax bills.
Limits of the parcel data
Listed acreage is an assessed number; only a licensed surveyor can set the real corners for a parcel near Plainfield. Owner names and values update on a schedule, so a recent sale near Plano may not show yet.
