Initial analysis

The two-unit residential building at 3019 E 80th Street in Chicago's South Chicago neighborhood, owned by Matthew Patek, was constructed in 1895 and has accumulated notable recent activity that warrants attention. Most concerning are seven open building code violations recorded on August 27, 2024, all stemming from complaint-driven inspections that remain unresolved as of October 2023. These violations, given their open status, suggest current compliance issues that could impact resident safety and comfort. The property has also experienced various service-related challenges, as evidenced by twelve 311 service requests over the past seven years. While many of these issues have been resolved, they indicate ongoing maintenance and environmental concerns in the vicinity. The most recent service requests from January 2026 included rodent issues, vacant lot concerns, recycling cart matters, and a missed garbage collection, all of which have been marked as closed. Earlier requests from mid-2025 involved tree-related issues (both emergency and debris cleanup) which were also addressed. The building's permit activity over the past seven years is minimal, with only three permits recorded, though the nature and scope of these permits are not detailed in the available data.

Risk rating

How 3019 E 80Th St'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

Grade A–B — Low risk

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
