When a listing near Good Hope mentions a lot number, you'll need the Macomb plat map to make sense of it. This Macomb guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
Tracking down the Macomb plat map
For a subdivision near Sciota, look for the plat book reference on the parcel record; use it to request a copy.
Getting to the right map
Parcels around Tennessee appear on the McDonough County WTH GIS map, free to use and open without a login. For acreage around Good Hope, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Good Hope, the record panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
When there's no plat
Acreage around Bardolph outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Neighboring parcel maps
McDonough County borders Fulton County, Hancock County, Henderson County, Schuyler County, and Warren County, all with their own assessor records. Acreage along the edge near Tennessee can show up in two county records, so check the adjacent map too. Out toward Tennessee, our state page links each neighboring county map across Illinois.
Where Macomb fits in
Macomb sits in McDonough County, Illinois, so its parcels are on the county's map. Macomb is also the county seat, handy when you need recorded documents. Local government in Macomb handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the town limits near Colchester often answers to county rules, not municipal ones.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Industry, but coverage can be spotty out of town. A screenshot of the parcel near Sciota with its ID is a good backup.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so a tree line near Colchester may sit several feet off the line on screen. For property near Colchester, records update in batches, so a deed recorded last month might lag behind.
Offices that can help
Anything recorded against property around Sciota are with 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 Sciota are for the local planning and health departments, and the answer depends on jurisdiction.
Replats and vacations
An amended plat may change lots around Tennessee, so check for later filings; street vacations near Bardolph show up in the records too.
How a plat differs from the tax map
The McDonough County WTH GIS map draws parcels for taxes, whereas the plat carries surveyed dimensions.
How land is described here
Illinois follows the Public Land Survey System, which means a tract near Industry is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Bardolph vary in size. Keep the legal description for land near Bardolph for any title or survey request.
McDonough County in a few facts
Macomb serves as the county seat, which is where the courthouse records live. Other places on the map include Good Hope, Colchester, Bardolph, and Sciota, where town lots give way to larger tracts. Around 26,839 people call McDonough County home (Census Bureau estimate, 2023) across about 589 square miles. McDonough County was formed in 1826, so old deeds can run back a long way.
Reading the plat sheet
For property near Good Hope, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Backing up the map with records
When the details count, get the recorded deed from the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Industry only summarizes it. Older tracts near Bardolph can sit on several deeds, and a title company earns its fee on a real sale.
Online indexes and office visits
With a lot near Colchester, many recorder offices offer an online index, while others require a visit or a request; small fees are common.

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.
