Unlock complete reportThe six-unit residential building at 5906 W Diversey Ave in the Belmont Cragin neighborhood, owned by William Te Lai Chan, was constructed in 1972 and has experienced an unusual clustering of maintenance and safety-related issues in the latter half of 2025. Between August and December 2025, there were six notable service requests, including three infrastructure-related concerns: a sewer cave-in inspection, an alley sewer inspection, and a street light outage, which could potentially impact both safety and resident comfort. The building also faced challenges with physical maintenance and public space upkeep, evidenced by requests for graffiti removal and ice/snow removal services. Additionally, there was a rodent control complaint filed in August 2025, indicating possible pest management concerns. While all 14 service requests logged in the past seven years have been officially closed, the recent concentration of issues in 2025, particularly those affecting basic infrastructure and safety, merits attention.

How 5906 W Diversey 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
