Unlock complete reportThe three-unit residential building at 3412 N Janssen Ave in the Lake View neighborhood, owned by Robert C La Morte, has been standing since 1898 and is currently recorded as having one parcel. Over the past seven years, the property has generated a limited number of 311 service requests, with only three logged since 2024. The most recent complaint, filed in June 2026, related to cab service feedback, while earlier issues included a snow-related complaint about uncleared sidewalks in February 2025 and one regarding e-scooter parking in August 2024. All three complaints have been closed, and notably, none of the reported issues appear to reflect on the building's structural integrity or resident safety, as they primarily concern external services and public space management. The relatively low number of complaints over this extended period could suggest either effective property management or limited reporting activity, though this cannot be definitively determined from the available data alone.

How 3412 N Janssen 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 3443 buildings in this neighborhood, 723 are predicted to be safer.
