The official viewer behind the Granite City GIS map
Parcel maps here are usually run by the county, not the town, so for Granite City the go-to is the Madison County parcel viewer.
The free map to start with
Begin with the Madison County parcel viewer; it covers every assessed parcel from Hartford to Pontoon Beach. If you only know roughly where the land is, pan along Interstate 255 and select the outline. With a lot near Glen Carbon, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Limits of the parcel data
Acreage on the record is a tax-roll number; just a licensed surveyor can set the real boundary for a parcel near Venice. With a lot near Roxana, records update in batches, so a deed recorded last month might lag behind.
Land on the county line
Madison County meets Bond County, Clinton County, Jersey County, Macoupin County, and Montgomery County, and each of those keeps its own parcel map. Acreage along the edge near Pontoon Beach can show up in two county records, so open the adjacent map too. For a tract near Pontoon Beach, our state page lists every bordering county map for Illinois.
Recorded documents worth pulling
When the details count, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Pontoon Beach only summarizes it. Inherited tracts near Glen Carbon may go back through a long string of deeds, so a title company is worth hiring on a real sale.
Legal descriptions in Illinois
Illinois uses the Public Land Survey System, which means a tract near Pontoon Beach is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Glen Carbon odd-sized. Write down the legal description for the tract near Pontoon Beach before you request a deed or survey.
Where Granite City fits in
Granite City is part of Madison County, Illinois, which means parcel data comes from the county. Closer to Roxana, City or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Roxana often falls under county rules instead.
Searching the map
By address works best for lots in Granite City; owner search often wants the surname first. For property near Venice, searching by parcel number never misses, and it's printed on tax bills.
A quick look at the area
Edwardsville serves as the county seat, which is where the courthouse records live. You'll also find Pontoon Beach, Venice, Hartford, and South Roxana, where town lots give way to larger tracts. Around 262,752 people live in Madison County (Census Bureau estimate, 2023) on some 716 square miles. Madison County was formed in 1812, so old deeds can run back a long way. Features like Mississippi River and Horseshoe Lake are easy to spot when you zoom out from Venice.
