Before you buy a lot near East Alton with a plan in mind, look at the Wood River zoning map early: the zoning district decides setbacks, lot size and uses. This Wood River guide covers: which office sets the rules for a lot, how to match a parcel to its district, and when a variance or rezoning comes up.
Which office controls the Wood River zoning map
Within municipal limits, the local government adopts its own zoning map, so a lot in Wood River answers to that map. Past the city line, around Roxana, the county's ordinance, if any, takes over; confirm with the county office. A fast way to settle it: ask whether the parcel near South Roxana is inside the boundary.
The viewer Madison County publishes
Your first stop is the Madison County parcel viewer; it covers each assessed parcel around Hartford and Alton. On ground around Hartford, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Alton, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
City limits and county records
Wood River lies within Madison County, Illinois, and the county assessor maps its lots. For acreage around Hartford, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits near South Roxana often follows county rules rather than the town's.
Where the recorded documents are
For anything that matters, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Roxana only summarizes it. Long-held tracts around Alton can trace back through a long string of deeds, and a title company is worth hiring on a real sale.
Matching a lot to the Wood River zoning map
Some planning offices post the Wood River zoning map as a PDF; staff can confirm the district if you send the parcel ID. For property near Roxana, district codes like R-1, C-2 or A-1 point to a table of rules in the ordinance; the letters vary from place to place.
When a parcel crosses a boundary
Madison County borders Bond County, Clinton County, Jersey County, Macoupin County, and Montgomery County, all with their own assessor records. A tract near the line by Alton can be split across two assessors' files, so open the adjacent map too. If you're looking near East Alton, our state page links each bordering county map for Illinois.
Who handles what
