File online, in-person, or by mail. Pay any applicable fees (based on project scope).

Compliance Tips
- ✓ Work with licensed, local contractors who know Knox County codes and can pull permits. Document everything—photos, receipts, inspections—for insurance and resale.
- ✓ Choose code-approved materials rated for Illinois snow/wind loads. Schedule inspections promptly to avoid rework.
- ✓ Factor in timelines—permits add days or weeks; start early. If DIY, confirm you're allowed and get permit yourself.
- ✓ Insurance check: Notify your insurer before work—unpermitted roofs may void coverage.

Zoning
Zoning matters—some districts limit roof types (e.g., no reflective materials). Check your property's zoning and any overlays before starting.
Historic Properties
Historic areas in Rio may need extra review. Roofing changes could require preservation board approval to match original style.
