Initial analysis

The two-unit residential building at 4229 S Washtenaw Ave in Brighton Park, owned by Gilberto Ornelas, has a documented history of maintenance and pest-related issues over recent years. Built in 1908, this property has experienced several notable events, with the most pressing concern being an unresolved building code violation filed in February 2026, following a complaint-driven inspection. The building has also been subject to multiple pest control interventions, specifically for rodent issues, with two service requests for rat complaints in June 2025, both of which have been closed. Of particular note is a recent building violation complaint filed in February 2026, which appears to have been generated in connection with the ongoing building code violation that remains open and unresolved as of October 2023. A review of the building's record over the past seven years shows minimal total violations and service requests, with only one documented building violation and three 311 service requests in total, suggesting that while recent issues have emerged, the property's overall violation history has been relatively limited.

Risk rating

How 4229 S Washtenaw 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.
