Understanding Building Safety in Chicago
Chicago has 174,219 buildings in our database, scored from 0 to 100 based on government violation records. The average safety score is 51/100, with 100% of buildings having at least one violation on record. This is moderate — many buildings have room for improvement in maintenance and safety compliance.
Before signing a lease in Chicago, we recommend checking your potential building's safety score. Buildings with scores below 50 may have unresolved structural, fire safety, or habitability issues. Open violations are especially important — they indicate problems that have been officially documented but not yet fixed by the landlord.
What do the scores mean?
- 80–100: Excellent — minimal or no violations, well-maintained building
- 60–79: Good — some past violations but generally resolved promptly
- 40–59: Fair — multiple violations, some may still be open
- Below 40: Poor — significant unresolved safety concerns, proceed with caution
