Illinois requires frost-depth footings of 42 inches in the northern half of the state including Chicago and 36 inches in southern regions. Full basements are standard in most residential construction, with poured concrete or CMU walls meeting lateral load requirements. The Chicago Building Code requires professional engineering for any structural modifications in multi-family buildings. Downstate projects follow IRC prescriptive standards for single-family residential. All new residential construction in Illinois should incorporate radon-resistant features per IEMA recommendations, as much of the state lies in EPA Zone 1 for radon potential.

Northern Illinois sits on heavy clay glacial till that creates moderate shrink-swell pressure against foundation walls, requiring proper backfill and drainage. The Chicago area's clay soils often need over-excavation and granular backfill around basements. Southern Illinois limestone karst terrain can produce sinkholes, particularly in the St. Louis metro east side. Former coal mining areas in central and southern Illinois may have subsidence risk from abandoned underground mines. The Illinois Mine Subsidence Insurance Fund provides coverage for affected properties. High water tables along the Illinois and Mississippi River corridors can require sump systems and waterproofing for basements.
