Unlock complete reportThe 3-unit residential building at 3830 N Mozart St in Chicago's Irving Park neighborhood, owned by Roslyn Real Estate LLC, was constructed in 1910 and has had 17 service requests filed under its ownership over the past seven years. Most recently, in March 2026, there were two street light-related complaints (one to the Alderman's office and the other to 311 City Services), and shortly before that, two additional street light complaints were filed in January 2026, all of which have been resolved. The building's service request history shows no documented internal maintenance issues or safety concerns within the property itself, as all recorded complaints pertain to street lighting in the vicinity rather than building-specific problems. The limited number of service requests over this period - both for the building and its owner properties - suggests minimal ongoing operational issues, though it's worth noting that the most recent complaints were clustered together within a short timeframe in early 2026.

How 3830 N Mozart 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
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 3714 buildings in this neighborhood, 2600 are predicted to be safer.
