Initial analysis

The three-unit, 1920 vintage building at 3717 W Montrose Ave in Chicago's Irving Park neighborhood, owned by Gary R Carlson, has experienced numerous regulatory interactions over the past seven years, with particular attention to recent events. Most significantly, there has been a concerning pattern of building violations, with a total of 526 recorded against the property, along with 27 scofflaw violations, suggesting persistent noncompliance issues. Recent activity from 2024 to September 2025 shows five 311 service requests related to building and sanitation code violations, with one request specifically regarding garbage cart maintenance. The building's permit history shows 79 permits issued over seven years, though only two permits have been recorded in the past seven years, which warrants attention given the building's age and maintenance needs. While there was one environmental complaint recorded in the past seven years, the most pressing concern appears to be the high volume of building violations, which represents the majority of regulatory interactions with this property.

Risk rating

How 3717 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.
