Unlock complete reportThe three-unit residential building at 3975 N Normandy Ave in the Dunning neighborhood, owned by Derek Kozinski, has been standing since 1908 and has recorded relatively few incidents over its long history. Of particular note in recent data is a concerning pattern of water supply issues during early 2026, with four documented "No Water" complaints within a three-month period, all of which were subsequently resolved. The building's more distant history shows two administrative code violations: a minor infraction in 2009 related to section 11-5-023 which incurred a $25 fine, and an earlier issue from 2002 concerning section 11-4-260 that resulted in no fines. The property has had minimal municipal interaction overall, with only ten documented 311 service requests in the past seven years, including a pothole complaint from February 2026 which was addressed. While the recent water supply issues are the most significant concern in the current record, it's worth noting that these problems appeared to be isolated incidents rather than an ongoing pattern, as no similar complaints were recorded before or after this three-month period.

How 3975 N Normandy Ave'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 1058 buildings in this neighborhood, 286 are predicted to be safer.
