Unlock complete reportThe three-unit residential building at 5047 S Kostner Ave in Archer Heights, owned by L Dziedzic, has a mixed record over the past seven years. Built in 1959, the property has experienced significant regulatory scrutiny, with 25 building violations recorded during this period, though all six documented complaint-driven inspection violations from December 2021 have been resolved. The building has also generated 49 service requests through the 311 system, with the most recent activity occurring in 2026. Recent 311 requests primarily relate to traffic signage issues, with three one-way sign repair requests and one stop sign request in June and May 2026, and three city vehicle sticker violation complaints between January and February 2026. While these recent violations and service requests suggest ongoing maintenance and compliance challenges, particularly in terms of signage and parking enforcement, it's worth noting that the building's structural violations from 2021 were addressed and closed, indicating some responsiveness to regulatory requirements.

How 5047 S Kostner 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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 843 buildings in this neighborhood, 835 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
