Do I need a permit for screen enclosure or pool cage in Unincorporated Cook County?
Yes. In Illinois, screen enclosure or pool cage generally requires a permit, and Unincorporated Cook County is no exception.
In Cook County, permits outside the cities are handled by the Cook County Department of Building and Zoning, reachable on 312-603-0500 at https://www.cookcountyil.gov/agency/building-and-zoning. Its online permit portal is https://bzpermits.cookcountyil.gov/permit-status/. This office permits the unincorporated parts of Cook County. If your address sits inside a municipality, that municipality issues the permit instead. An attached enclosure is a structural addition, so expect a plan review and a footing and attachment inspection. Most Illinois jurisdictions treat a screen room or enclosed porch as a structure requiring a permit and setback or zoning review. Many local codes require footings designed for the local frost depth. The frost depth and the structural requirements come from the code edition your jurisdiction has adopted rather than from a statewide Illinois residential code.
