Initial analysis

The two-unit residential building at 4515 W Montana St in the Hermosa neighborhood, owned by Ildeberto Santacruz, is a 1912 structure that has experienced several notable maintenance issues in recent years. Most significantly, there has been a recurring problem with rodent activity, with four rat-related service requests filed between April and June 2026, all of which have been marked as closed. The property has also faced challenges related to tree maintenance, with two tree trimming requests submitted in April 2026, though these requests are no longer being accepted, as well as one tree emergency service request in June 2026. The building's total of 31 service requests over the past seven years, while not all detailed in the current period, indicates a history of maintenance interactions with city services, though the records primarily show concentrated issues in mid-2026 rather than a consistent pattern of recent concerns.

Risk rating

How 4515 W Montana 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.
