Unlock complete reportThe six-unit residential building at 1509 W Thomas St in Chicago's West Town neighborhood is an 1889 structure currently owned by Dawn De Bias. The building's documented history spans several years, with the most recent activities occurring in 2024-2025, including a tree emergency, a water lead test kit request, a fly dumping complaint, and an information-only call to 311 - all of which have been closed. Looking further back, there is an environmental complaint from 2020 regarding construction and demolition activities, though no violations were found, and two administrative hearing cases from April 2009 related to noise and building code violations (specifically codes 7-28-080 and 13-32-125(2C)), were closed with no fines imposed. The building's 311 service request history over the past seven years shows a total of four service requests, which is relatively low for a multi-unit residential building. The property's documented issues primarily relate to external matters such as tree and water concerns, rather than internal building problems, and while the building's age is considerable at 134 years old, there are no major safety or resident experience issues recorded in the available data.

How 1509 W Thomas 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 2255 buildings in this neighborhood, 744 are predicted to be safer.
