Buying a lot in a subdivision near Carbon Hill? What you want is the Channahon plat map, as it records the lot layout that deeds refer to. This Channahon guide covers: where plats are filed, plat versus tax map, and the details that matter to buyers.
Who keeps the Channahon plat map
For a lot in Channahon, the deed usually cites the plat; that makes the request quick.
Where the parcel data lives
Begin with the Grundy County parcel viewer; it covers every tax parcel around Morris and Godley. For acreage around Diamond, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Carbon Hill, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Metes and bounds instead
Rural land near Godley that was never subdivided may have no plat at all; look for a recorded survey for land near Coal City.
City limits and county records
Channahon lies within Grundy County, Illinois, and the county assessor maps its lots. For a home near Morris, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits near Morris usually falls under county rules, not municipal ones.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements covering ground around Coal City are kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder). Closer to Carbon Hill, have ready the document number shown in the record panel so staff can find the deed fast.
Offices that can help
For assessment questions about property around Godley belong with the Supervisor of Assessments, working with township assessors, since that office keeps the assessment data. Questions about what you can build around Minooka are for the local planning and health departments, and the answer depends on jurisdiction.
Two different maps
The Grundy County parcel viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
Details on the Channahon plat map
If the land is near Godley, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Getting a copy
For property near Coal City, some counties put plat images online, otherwise call or visit with the reference; small fees are common.
Replats and vacations
An amended plat may change lots around Diamond, so check for later filings; street vacations near Morris show up in the records too.
Neighboring parcel maps
Grundy County meets Kankakee County, Kendall County, LaSalle County, Livingston County, and Will County; every one of them runs a separate parcel map. Acreage along the edge near Carbon Hill may show up across two assessors' files, so open the adjacent map too. In and around Carbon Hill, our state page links each bordering county map across Illinois.
Grundy County in a few facts
Morris holds the county offices, which is where the courthouse records live. Smaller places on the map include Minooka, Carbon Hill, and Diamond, each with its own cluster of lots. About 53,578 people live in Grundy County (Census Bureau estimate, 2023) on some 418 square miles. Grundy County was formed in 1841, and some chains of title near Godley are long.
Reading the legal description
Illinois is laid out under the Public Land Survey System, so deeds around Morris reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Morris can be irregular. Write down the legal description for the tract near Carbon Hill for any title or survey request.
On site with the map
Most viewers work in a phone browser, handy when you're parked on a road near Minooka, but coverage can be spotty out of town. A saved image of the lot near Minooka and its lines is a good backup.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so a tree line near Carbon Hill may sit a few yards off the line on screen. For property near Carbon Hill, owner names and values update on a schedule, so a deed recorded last month might lag behind.

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.
