Unlock complete reportThe two-unit, 1894 vintage building at 3741 N Janssen Ave in Lake View, currently owned by Daniel Pieringer, has maintained a relatively quiet record over the past seven years, with minimal documented interactions with city services. The property has generated only two 311 service requests during this period, both of which were related to tree trimming and were closed in 2024 (one in October and one in August). These tree trimming requests are particularly notable as they were filed under the designation "NO LONGER BEING ACCEPTED," suggesting that they were part of an official program or initiative that has since concluded. Additionally, there has been only one building permit issued in the past seven years, though the specific nature of this permit is not detailed in the records. The overall low volume of service requests and permits could indicate either proactive property maintenance or minimal required interventions, though this alone does not necessarily reflect on the building's current condition or inhabitability.

How 3741 N Janssen Ave 2'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, 207 are predicted to be safer.
