Initial analysis

The two-unit residential building at 5304 W Cornelia Ave in Portage Park, owned by Tadeusz Lucyna Mirek, has a relatively limited but noteworthy record over the past seven years. Built in 1925, this property has experienced two building code violations, three building permits, and four 311 service requests in recent years. The most significant recent concern involves an open water lead test kit request from November 2024, which indicates potential public health concerns regarding water quality. There are also two open service requests from 2024: one for sidewalk inspection in April and another about permit-related inspections from April 2023. The property has seen some recent activity with resolved violations related to permit inspections in February 2024, and two closed service requests from 2025 regarding garbage cart maintenance and graffiti removal. While the number of complaints and violations is relatively low for a multi-unit building, the presence of unresolved inspection-related issues and the open water lead testing request warrant attention to ensure resident safety and compliance with local regulations.

Risk rating

How 5304 W Cornelia 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
