Ahead of any building plan near Maryville, look at the Edwardsville zoning map first: a district label decides setbacks, lot size and uses. Covered here for Edwardsville: who controls zoning for a given parcel, how to match a parcel to its district, and what to ask the planning staff.
The Edwardsville zoning map: start here
Within municipal limits, the town or city normally writes the zoning code, which means a parcel in the city follows that code, at least around Alton. For rural land toward South Roxana, the county's ordinance, if any, takes over; ask the county planning office to be sure. The quickest way to tell which applies: look for a city limits layer in the Madison County parcel viewer.
Where the parcel data lives
Lots and tracts near Pontoon Beach can be looked up on the Madison County parcel viewer, free to use and open without a login. Without an address in hand, pan along Interstate 255 until the lines appear, then click inside the one you want. For a tract near South Roxana, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.

Edwardsville, IL: the basics
Edwardsville is part of Madison County, Illinois, so its parcels are on the county's map. As the county seat, Edwardsville hosts the courthouse, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. Closer to Glen Carbon, 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. Lots just outside the city limits out by Maryville often answers to county rules, not municipal ones.
Finding a parcel's zoning district
Some planning offices post the Edwardsville zoning map as a PDF; if you can't find it, ask staff for the district by parcel number. For a home near Roxana, labels such as R-1, B-2 or AG stand for residential, commercial or agricultural districts; the letters vary from place to place.
Which office to call
If the acreage or value on a parcel near Pontoon Beach looks off go to the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Zoning, permits and septic questions near Hartford need the planning or permitting office, depending on whether the land is inside town limits.
