Unlock complete reportThe three-unit residential building at 2937 W 40th Street in Brighton Park, owned by Zai Wen Zhang, has a combined total of 15 building code violations in the past seven years, with a concerning cluster of unresolved issues dating from August 2019 when multiple complaint-driven inspections were conducted. While some violations from this inspection have been resolved, several remain open. The building has received minimal attention in terms of permits during this period, with only two permits issued. The property has generated four 311 service requests over the last seven years, with the most recent being a finance parking code enforcement review in May 2026 and earlier issues including sanitation code violations, a missing street light pole door complaint, and a recycling pickup request between March and August 2025, all of which were resolved. Given the age of the building (constructed in 1916) and the significant number of violations recorded, particularly the unresolved issues from 2019, the property presents notable maintenance and regulatory compliance concerns.

How 2937 W 40Th St 2'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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood

Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3962 buildings in this neighborhood, 3883 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
