Initial analysis

The two-unit residential building at 5935 W Patterson Ave in Portage Park, owned by Erika Velasco, has a documented history dating back to its 1905 construction. The property has experienced an unusual pattern of recent issues, with five open building code violations recorded in late 2025, all of which were generated from complaint-driven inspections. Prior to these, the most recent building code violation was noted in October 2024, while a permit-related inspection violation from November 2019 has been resolved. The building has also generated significant municipal service requests, totaling 33 in the past seven years. Most notably, there has been a cluster of 311 service requests in 2026, including multiple reports of abandoned vehicles and rodent issues, though several of these have been resolved. An open pothole complaint and a sewer cave-in inspection request from June 2026 remain unresolved. Historical environmental concerns include two air pollution work orders, one from 2006 and another from 2016, both of which were resolved.

Risk rating

How 5935 W Patterson Ave 2Nd'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.
