Initial analysis

This two-unit residential building, located at 4321 W Cortez St in the Humboldt Park neighborhood, is a single-parcel property owned by Milton Henry and was constructed in 1953. Over the past seven years, the property has generated only two documented 311 service requests, both of which were relatively minor and recent in nature. The most recent request, filed on September 10, 2024, was an information-only call to the 311 City Services department, which typically indicates an inquiry that did not require any service intervention. Prior to that, on July 17, 2024, there was a tree emergency reported to the Streets and Sanitation department, though the specific nature and impact of this issue are not detailed in the records. While the building's 311 service request history shows minimal usage of city services, with only two incidents in seven years, it's important to note that building conditions and resident experiences cannot be fully assessed through service request data alone, as not all issues may be reported through the city's 311 system.

Risk rating

How 4321 W Cortez St 1'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
99thpercentile
