Frequently Asked Questions
What does a structural inspection include?
A structural inspection evaluates the foundation, floor joists, beams, columns, load-bearing walls, roof framing, and connections. The inspector looks for deflection, cracking, rot, insect damage, improper modifications, and code violations. A written report details findings and recommends repairs.
How much does a structural inspection cost in Illinois?
Structural inspections typically cost $500 to $1,200, depending on property size and complexity. A licensed Professional Engineer's stamped report typically costs $600 to $1,200. Structural inspections are particularly important for older housing stock.
When is a structural inspection needed in Illinois?
A structural inspection is recommended when a home inspector flags concerns about foundation cracks, sagging floors, bowing walls, or visible framing damage. It is also advisable for properties that have undergone major renovations, additions without permits, or properties damaged by flooding, severe weather, or fire.
Who can perform structural inspections in Illinois?
Licensed Professional Engineers (PE) are the gold standard for structural inspections. Verify your inspector's PE license through the Illinois Department of Financial and Professional Regulation (IDFPR), which administers the Professional Engineering Practice Act (225 ILCS 325/). Some experienced home inspectors also provide structural assessments, but only a PE can provide a stamped report accepted by lenders and municipalities.
