Portage Park, Chicago IL 60634 13174020410000 6 units · 1958

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The six-unit residential building at 5857 W Montrose Ave in Portage Park, owned by Norbert Mika, has been standing since 1958 and has undergone limited documented activity over the past seven years. The property owner has been associated with 10 total parcels and their ownership record shows 3 building permits issued within this timeframe. While the building's 311 service request history shows only two requests directly related to the property in recent years - one for tree trimming in November 2025 and another regarding an abandoned vehicle in May 2024 - these were external to the building itself and are not directly indicative of building conditions.

Risk rating

How 5857 W Montrose 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
18thpercentile
