Unlock complete reportThe four-unit residential building at 3651 W Montrose Ave in Chicago's Irving Park neighborhood, currently owned by Andres & Mirna Lopez, is a century-old structure dating back to 1915. The building's recent history from the past seven years reveals some concerning patterns, particularly in 2022 when three complaint-driven inspection violations were documented on March 14, all of which remain unresolved as of October 2023. These open violations, while not specified in nature, indicate ongoing regulatory concerns that have not been addressed over the past year and a half. Additionally, there was one 311 service request related to a rodent baiting/rat complaint in April 2025, which has been marked as closed. This pest-related issue suggests potential concerns about building maintenance and hygiene, though the prompt response and resolution could indicate the problem was effectively addressed. The relatively low number of recorded violations and service requests over the past seven years (three building violations and one 311 request) could be interpreted as the building having minimal documented issues, though the significance of the ongoing open violations from 2022 warrants attention.
How 3651 W Montrose Ave 3'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3714 buildings in this neighborhood, 3491 are predicted to be safer.
