Unlock complete reportThe three-unit residential building at 1639 S Throop Street in Chicago's Lower West Side is a three-parcel property built in 1883 and currently owned by Andres Alba. The building's record over the past seven years shows a total of six building violations and 33 service requests, with all recent service requests in 2024-2025 primarily related to street lighting issues, including three separate street light outage complaints in December 2024 alone, and two additional such complaints in May 2025. Prior to these, there was one tree removal inspection request in November 2024, though this was not directly related to the building's condition or infrastructure. While the building has experienced several code violations in recent years, the majority of reported issues appear to be related to external infrastructure rather than the building itself. The property has maintained regular communication with city services, as evidenced by the frequency of service requests.

How 1639 S Throop 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, 2425 are predicted to be safer.
