When a deed near Millington says lot and block, look up the Plano plat map it refers to. Covered here for Plano: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Plano plat map
For a lot in Plano, look for the plat book reference on the parcel record; that makes the request quick.
Opening the official parcel viewer
Lots and tracts near Millington are published on the Kendall County parcel viewer, which opens without registering. For acreage around Newark, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Yorkville, write down the parcel ID from that panel; every clerk in the county will want it.
A word on accuracy
Listed acreage is a tax-roll number; just a licensed surveyor sets the real corners on land around Yorkville. On ground around Oswego, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Getting answers from the right desk
Recorded documents for a parcel near Oswego 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 Montgomery go to planning, building or health offices, depending on whether the land is inside town limits.
City limits and county records
Plano lies within Kendall County, Illinois, so its parcels are on the county's map. For land near Newark, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits near Montgomery often follows county rules, not municipal ones.
Recorded plat or GIS layer
Where lines don't match in Plano, the recorded plat and a survey control.
Kendall County in a few facts

Deeds, plats and who keeps them
Before you sign anything, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Yorkville only summarizes it. Inherited tracts around Millbrook can sit on several deeds, so a title company can sort it out on a real sale.
What a plat shows
If the land is near Newark, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Amended plats
