Ahead of any building plan near Pontoon Beach, pull up the Granite City zoning map first: the zoning district decides setbacks, lot size and uses. In this Granite City guide: which office sets the rules for a lot, matching a lot to its zoning district, and what to ask the planning staff.
Getting started with the Granite City zoning map
Inside town or city limits, the local government adopts its own zoning map, which means a parcel in Granite City follows that code. For rural land toward Venice, the county may have its own zoning, or none at all; confirm with the county office. To find out which side of the line a parcel is on: look for a city limits layer in the Madison County parcel viewer.
The free map to start with
Go first to the Madison County parcel viewer; it includes each tax parcel around Roxana and South Roxana. If you only know roughly where the land is, follow Interstate 255 on the aerial and select the outline. For land near Hartford, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and often a sale date.
How land is described here
Illinois follows the Public Land Survey System, which means a tract near Roxana 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 corrections make some sections near Pontoon Beach odd-sized. Write down the legal description for the tract near Venice for any title or survey request.
A word on accuracy
Tax maps are drawn for assessment, not surveyed, so a fence near Hartford may sit several feet off the line on screen. For a tract near Venice, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Calling planning staff
Have the parcel ID ready and describe the plan for the lot near Venice; ask what's allowed by right and what needs a permit. Ask whether a parcel near South Roxana meets current minimum size, since some older splits don't.
Where Granite City fits in
Granite City is part of Madison County, Illinois, and the county assessor maps its lots. With a lot near Hartford, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits toward Roxana often follows county rules instead.
Offices that can help
For assessment questions about property around South Roxana go to the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Building or septic questions for a lot near South Roxana need the planning or permitting office, and the answer depends on jurisdiction.
Finding a parcel's zoning district
Start by finding the parcel on the Madison County parcel viewer, copy its parcel ID, and match it to the adopted zoning map. For a parcel near South Roxana, labels such as R-1, B-2 or AG stand for residential, commercial or agricultural districts; the letters vary from place to place.
Reading the ordinance
For any structure near Glen Carbon, the numbers to find are lot size, setbacks, height and coverage. For a parcel near Hartford, overlay districts, such as floodplain, historic or airport zones, can add rules on top of the base district.
Next door to Madison County
Madison County touches Bond County, Clinton County, Jersey County, Macoupin County, and Montgomery County; every one of them runs a separate parcel map. Acreage along the edge near Roxana can show up in two county records, so open the adjacent map too. For a parcel near Venice, our state page lists every bordering county map across Illinois.
Deeds, plats and who keeps them
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 Roxana only summarizes it. Long-held tracts around Roxana may go back through several deeds, so a title company earns its fee before a purchase.
Building permits and inspections
Once zoning clears a project near Pontoon Beach, a building permit is a separate step; septic or sewer and driveway access are often reviewed too.
When a plan doesn't fit
If your plan near Glen Carbon doesn't fit the district, staff can explain which process fits.
