Initial analysis

The three-unit residential building at 5124 S Kostner Ave in Archer Heights, owned by Fernando Mones Sr., has maintained a relatively low record of service requests and permits over the past seven years. The property, constructed in 1987, has had minimal reported issues during this period, with only one documented 311 service request (a graffiti removal request from December 2024) and one building permit on record. The owner's overall history shows four service requests, though most appear to be routine matters rather than significant concerns. Both the building and owner records suggest good property maintenance practices, with no major safety incidents or recurring maintenance issues documented in the available data. The only notable external issue was the recent graffiti incident, which was promptly addressed and closed through the 311 system.

Risk rating

How 5124 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.

Neighborhood percentile
