Unlock complete reportThe four-unit residential building at 1634 S Ada Street in Chicago's Lower West Side, owned by Ignacia Casimiro, has been standing since 1888 and has recently experienced a concerning pattern of pest-related issues. Over the past seven years, there have been a total of nine service requests recorded through the 311 system, with an alarming concentration of rodent-related problems in the most recent months of 2025. Between June and October 2025, there were four documented rodent baiting/rat complaints, all of which have been closed but indicate a potential ongoing pest control challenge. Additionally, there were three nuisance animal complaints filed during this same period, suggesting issues with either stray or uncontrolled animals in the vicinity. While all reported incidents have been closed, the recent clustering of pest-related complaints may be of particular interest when evaluating the building's current living conditions.

How 1634 S Ada 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
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 3674 buildings in this neighborhood, 2609 are predicted to be safer.
