Initial analysis

The 6-unit residential building at 4308 N Milwaukee Ave in the Portage Park neighborhood, owned by Wieslaw B Kalisz, has been in operation since 1921. The building's recent service request history from 2025-2026 primarily consists of municipal infrastructure issues, with a total of six street-related complaints being recorded. These include three street light-related issues (one being a daytime illumination problem), two pothole complaints, and one graffiti removal request. All these service requests have been addressed and closed by the relevant city departments, with the street light issues reported to CDOT's Department of Transportation and the graffiti complaint being handled separately. The building's overall service request history appears to be relatively minimal for a seven-year period, with no reported building-specific issues or resident complaints in the provided data. The pattern of service requests suggests a focus on external city infrastructure matters rather than building-specific concerns, with the most recent issues being primarily related to street maintenance and lighting rather than building conditions or resident services.

Risk rating

How 4308 N Milwaukee 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
27thpercentile
