Initial analysis

The two-unit residential building at 5025 W Byron St in Portage Park, owned by Javier Abrego Perez, has been standing since 1908 and has experienced several notable events over the past seven years. Most recently, in March 2026, there is an open request for a water lead test kit, which represents an important health-related concern that remains unresolved as of the report date. In 2025, there was a request for garbage cart maintenance that was successfully closed, and in late 2024, the property underwent tree-related activities, including both a tree planting request in November and a tree debris clean-up request in July, both of which were resolved. While the building's service request history shows relatively few incidents over the past seven years, the outstanding water lead test kit request is particularly significant given the potential health implications associated with lead exposure.

Risk rating

How 5025 W Byron 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

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.
