Unlock complete reportThe two-unit residential building at 4742 N Saint Louis Avenue in Chicago's Albany Park neighborhood has experienced several notable maintenance and environmental issues in recent years, particularly concerning water-related problems. The property, which dates back to 1913 and is currently owned by Johnny Ngo, has recorded multiple water-related incidents between 2024 and 2026, including a water in basement complaint in April 2026, a check for leak request in November 2025, and a current open request for a water lead test kit as of October 2025. The building's maintenance record also shows attention to external factors, with documented responses to a pothole in the street (September 2025) and a tree debris clean-up request (October 2024), both of which were properly closed out. While the property has had eight 311 service requests filed in the past seven years, most of these incidents have been resolved to completion, with the exception of the ongoing water lead test kit request. The concentration of water-related issues in recent years suggests this has been an area requiring particular attention, though all reported incidents have received appropriate municipal response.
How 4742 N Saint Louis Ave'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 2730 buildings in this neighborhood, 491 are predicted to be safer.
