Unlock complete reportThe 6-unit residential building at 1434 W Lexington St 3F, located in Chicago's Little Italy/UIC neighborhood, is a historic structure dating back to 1904 and currently owned by Doris Chyu. The building's recent maintenance record from the past seven years shows eight documented 311 service requests, with the most recent requests occurring in May 2026 for general information and recycling services. The property has experienced some environmental health concerns, including a rodent complaint in September 2025, though this was marked as closed. Two notable public health and safety-related service requests were made in 2025-2024: a water lead test kit request in August 2025 and an open inspection of the public way requested in November 2024, which may require follow-up. Additional routine maintenance requests have been made for recycling services and garbage cart maintenance, suggesting regular interaction with city services for basic building upkeep. While the building has had its share of service requests, most appear to be routine municipal service needs rather than serious safety issues, though the unresolved public way inspection as of November 2024 merits attention.
How 1434 W Lexington St 3F'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 1135 buildings in this neighborhood, 692 are predicted to be safer.
