Ahead of any building plan near Roxana, look at the Bethalto zoning map before anything else: the zoning district decides setbacks, lot size and uses. In this Bethalto guide: who controls zoning for a given parcel, how to match a parcel to its district, and the questions that save a wasted trip.
Getting started with the Bethalto zoning map
Within municipal limits, the local government adopts its own zoning map, so property inside Bethalto follows that code. For rural land toward Wood River, the county's ordinance, if any, takes over; ask the county planning office to be sure. To find out which side of the line a parcel is on: ask whether the parcel near Alton is inside the boundary.
Opening the official parcel viewer
Go first to the Madison County parcel viewer; it covers each tax parcel from Wood River to Roxana. In and around Alton, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Alton, write down the parcel ID while you have it open; every clerk in the county asks for it first.
Places you'll see on the map
Edwardsville holds the county offices, where most land records are kept. Smaller places on the map include Wood River, East Alton, Roxana, and Alton, where town lots give way to larger tracts. Roughly 262,752 people call Madison County home (Census Bureau estimate, 2023) on about 716 square miles. Madison County dates to 1812, and some chains of title near Hartford are long. Features like Mississippi River and Horseshoe Lake are easy to spot when you zoom out from Alton.
When a parcel crosses a boundary
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 East Alton may be split across two assessors' files, so open the neighboring map before you assume the acreage. For a home near Wood River, our state page links each bordering county map across Illinois.
Bethalto and the county around it
The town sits in Madison County, Illinois, which means parcel data comes from the county around Highland. In and around East Alton, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Land beyond the town limits near South Roxana often falls under county rules, not municipal ones.
Calling planning staff
When you call about land near South Roxana, give the parcel number and your intended use; ask what's allowed by right and what needs a permit. Ask whether a parcel near East Alton meets current minimum size, since some older splits don't.
Zoning is only step one
Once zoning clears a project near South Roxana, you still need building permits and inspections; septic or sewer and driveway access are often reviewed too.
Matching a lot to the Bethalto zoning map
Pull the parcel up on the Madison County parcel viewer, note the parcel number, and use it when you ask the planning office near Hartford. Short codes on the map stand for residential, commercial or agricultural districts; codes near East Alton may differ from the next town's.
What the district controls
On ground around Roxana, the ordinance spells out uses allowed by right, uses needing a permit, and uses not allowed. On ground around East Alton, overlays, whether historic, floodplain or corridor, can add rules on top of the base district.
Changing what's allowed
If the land is near Wood River, expect an application, a fee, notice to neighbors and a public hearing.
What the map can't tell you
Acreage on the record is a tax-roll number; just a licensed surveyor can set the real boundary for a parcel near East Alton. With a lot near Hartford, owner names and values update on a schedule, so a deed recorded last month might lag behind.
The paper trail behind a parcel
For anything that matters, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near South Roxana only summarizes it. Long-held tracts around Wood River can go back through a long string of deeds, and a title company is worth hiring if money is changing hands.
Reading the legal description
Illinois is laid out under the Public Land Survey System, so deeds around Alton reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Wood River can be irregular. Copy the legal description from the record for the parcel near South Roxana for any title or survey request.
