Tinley Park, IL Building Safety: Building Inspections (2026)

07(A)(3), lists the inspections the Building Official performs at each stage of a Tinley Park construction project. A footing inspection happens after excavation is complete and forms are set but before concrete is poured; a foundation wall inspection follows once forms are braced and reinforcing steel is tied in place, again before concrete pours. A rough inspection covers the roof, masonry, all framing, firestopping and bracing along with electrical, plumbing, mechanical and HVAC work, chimneys and fireplaces, and must happen before any insulation, lath or gypsum board goes up; the Code specifically bars a rough framing inspection until the electrical, plumbing and HVAC rough-ins are separately inspected and approved.

An insulation inspection follows the rough inspection but comes before lath or gypsum board installation, and nailing or screw-pattern checks cover lateral shear or bracing walls. Job sites must provide safe, slip-resistant access and be cleared of debris so the inspector can see all the work; ladders or level changes over 24 inches do not count as accessible. Work cannot proceed past the point covered by each successive inspection without the Building Official's written approval. or they roll to the next day. A final inspection follows completion of the building and any required fire department hydrostatic, alarm, or hood-suppression testing.
