Irving Park, Chicago IL 60641 13224320010000 8 units · 1966

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 8-unit residential building at 4157 W School in Chicago's Irving Park neighborhood was constructed in 1966 and is currently owned by Raymond L Stepanski. Over the past seven years, there have been very few service requests associated with this property, with only two significant 311 calls recorded in the most recent two years. The most recent incident was a closed stop sign repair request in March 2025, which was directed to the Alderman's office rather than a building-specific issue. Prior to that, in October 2024, there was a 311 information-only call that appears to be unrelated to the building's condition or tenant services. It's worth noting that the property has maintained a remarkably low number of documented service requests, with only two building-specific complaints noted in the past seven years, suggesting relative stability in building operations.

Risk rating

How 4157 W School Chicago'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
14thpercentile

Out of 3731 buildings in this neighborhood, 3209 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
