Opening the Minooka GIS map: start here
Parcel maps here are usually run by the county, not the town, which makes the Grundy County parcel viewer the main source for lots in Minooka.
The free map to start with
Your first stop is the Grundy County parcel viewer; it covers each assessed parcel from Morris to Carbon Hill. Near Channahon, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a parcel near Diamond, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Diamond, though signal can drop in rural spots. A saved image of the lot near Morris and its lines keeps working without signal.
Neighboring parcel maps
Grundy County touches Kankakee County, Kendall County, LaSalle County, Livingston County, and Will County, all with their own assessor records. A tract near the line by Coal City can be split in two county records, so look at the neighboring map before you assume the acreage. For land near Morris, our state page links each bordering county map across Illinois.
When the map won't load
When the map won't open around Carbon Hill, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
A quick look at the area
Morris serves as the county seat, which is where the courthouse records live. Smaller places on the map include Channahon, Carbon Hill, and Diamond. About 53,578 people call Grundy County home (Census Bureau estimate, 2023) on roughly 418 square miles. Grundy County was formed in 1841, and some chains of title near Channahon are long.
City limits and county records
Minooka is part of Grundy County, Illinois, so its parcels are on the county's map. For acreage around Morris, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits toward Morris generally falls under county rules rather than the town's.
Deeds, plats and who keeps them
For anything that matters, request the recorded deed from the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Morris only summarizes it. Inherited tracts near Diamond may go back through many deeds, and a title company can sort it out on a real sale.
Searching the map
Vacant ground near Diamond may lack an address, so zoom in from US Route 6 and click the outline. Around Coal City, searching by parcel number never misses, and you'll find it on tax statements.
Beyond the parcel lines
For a parcel near Coal City, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Printing and saving
Print or screenshot the parcel near Diamond with its ID visible, so you have it when calling an office.
Limits of the parcel data
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real boundary on land around Diamond. For a tract near Diamond, records update in batches, so a deed recorded last month might lag behind.
Which office to call
For assessment questions about property around Coal City go to the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Zoning, permits and septic questions near Diamond need the planning or permitting office, and the answer depends on jurisdiction.
How land is described here
Illinois follows the Public Land Survey System, so deeds around Godley reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Channahon can be irregular. Write down the legal description for the tract near Morris before you request a deed or survey.
What the record panel tells you
If sale dates appear, they help gauge the market in Minooka are a useful starting point; they're not an appraisal.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
