City of Chicago Building Violations, dataset 22u3-xenr.
About the data
This product narrows public Chicago building-violation records into a roofing review queue. It helps with research; it does not establish that work is still needed or that anyone wants contractor outreach.
What this snapshot shows
The preview was generated September 18, 2026. It filters roof, parapet, coping, shingle, gutter, and downspout language for easier review.
Before you act
Confirm the filing, record status, ownership context, and current property condition. A violation record is not a sales lead or proof of a present repair need.
