Initial analysis

The three-unit residential building at 6141 W Montrose Ave in Chicago's Portage Park neighborhood was constructed in 1974 and is currently owned by CTLTC 8002378451, with records showing one total parcel ownership. Over the past seven years, there have been five documented 311 service requests associated with this address. The most recent and most frequent issues have been related to street maintenance, with three identical pothole complaints filed and resolved in April 2026. Prior to these, there was one tree planting request and a blue recycling cart request in June and April 2024 respectively, both of which were successfully closed. The pattern of service requests suggests relatively limited maintenance needs, with a cluster of street-related complaints occurring in 2026, though these were addressed promptly through the appropriate city services.

Risk rating

How 6141 W Montrose 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.
