Unlock complete reportThe property at 6341 N Mobile Avenue in Norwood Park is a two-unit building owned by Marcin Topor and was constructed in 1941. The building's record over the past seven years indicates several concerning issues, most notably three unresolved complaint-driven inspection violations from February 28, 2020, which remain open as of the latest available data. These violations, while not specified in the record, warrant attention given their persistent unresolved status. Additionally, there was one 311 service request regarding a tree trimming that was created on February 20, 2025, though this request type is no longer being accepted and its status is listed as closed. The limited number of total service requests and violations on record might suggest a relatively stable building history, though the presence of multiple open violations from 2020 is particularly noteworthy given the time elapsed since they were recorded.
How 6341 N Mobile Ave 1St'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 892 buildings in this neighborhood, 776 are predicted to be safer.
