The official viewer behind the Wood River GIS map
A town may publish separate layers for zoning or utilities; check the Wood River website for one.
The viewer Madison County publishes
Your first stop is the Madison County parcel viewer; it includes each tax parcel around Bethalto and Alton. Without an address in hand, zoom in from Bethalto and click the parcel itself. Near Bethalto, the parcel card typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Printing and saving
Print or screenshot the parcel near Bethalto with its ID visible, so you have it when calling an office.
Wood River and the county around it
The town is part of Madison County, Illinois, so its parcels are on the county's map around Granite City. For a tract near Hartford, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits near Bethalto often answers to county rules, not municipal ones.
Search tips
Addresses are the easiest route inside Wood River; for owner searches, try last name first. On ground around East Alton, searching by parcel number never misses, and you'll find it on tax statements.
Before you lean on the lines
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near East Alton often sits several feet off the line on screen. If the land is near Alton, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Hartford, but coverage can be spotty out of town. A printout of the tract near Hartford helps when you meet an owner or agent.
Who handles what
Recorded documents for a parcel near East Alton come from the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Questions about what you can build around East Alton need the planning or permitting office, and the answer depends on jurisdiction.
Layers worth turning on
If the land is near Alton, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
Troubleshooting the viewer
If the viewer stalls on a phone near South Roxana, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.
When a parcel crosses a boundary
Madison County borders 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 Bethalto can show up in two county records, so check the adjacent map before you assume the acreage. Out toward Alton, our state page links each neighboring county map across Illinois.
The paper trail behind a parcel
The map is an index, not the title: deeds, plats and easements covering ground around Hartford are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts around Roxana may trace back through a long string of deeds, so a title company earns its fee before a purchase.

A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Roxana can be irregular. Write down the legal description for the tract near Bethalto when you talk to a surveyor.
Inside the parcel card
If sale dates appear, they help gauge the market near Bethalto give a rough idea of values; an appraiser is the real authority.
