Initial analysis

The two-unit residential building at 2515 N Oak Park Ave in the Montclare neighborhood, owned by Adelina Arroyo, has been standing since 1925. The property has generated a total of 19 service requests over the past seven years, with particular attention drawn to recent concerns about water quality, as evidenced by three open requests for water lead test kits from June 2026. This emerging pattern of water safety inquiries is noteworthy, potentially impacting resident health and safety. The building's maintenance history shows attention to surrounding infrastructure, with two street-related service requests for pothole complaints in late 2025, both of which were resolved. Additionally, there was a rodent control issue reported in April 2026, though this complaint has since been closed. While the property has maintained regular communication with city services, the recent cluster of water quality inquiries warrants attention as the most significant and potentially concerning issue on record, given their direct relevance to resident well-being.

Risk rating

How 2515 N Oak Park 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.
