Risk rating

How 321 S Jefferson St's risk score is calculated

We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
