Initial analysis

The two-unit residential building at 3905 W Montrose Ave in Chicago's Irving Park neighborhood, owned by Camelia Velazquez, has been standing since 1908 and has experienced a notable frequency of infrastructure-related issues in recent years. Over the past seven years, there have been 11 documented service requests through the 311 system, with the most recent spate of reports occurring in 2025, primarily centered around roadway maintenance concerns. Between June and July 2025, there were three documented complaints regarding potholes in the alley, all of which were subsequently closed. The property has also faced issues with street infrastructure, as evidenced by a pothole complaint in May 2026 and an abandoned vehicle complaint shortly before that. Additionally, there was one rodent-related complaint recorded and resolved in November 2025. While all reported issues have been closed through the appropriate channels, the concentration of roadway and alley maintenance concerns in 2025 suggests a period of persistent infrastructure challenges in the immediate vicinity of the property.

Risk rating

How 3905 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.
