Unlock complete reportThe 12-unit residential building at 4049 W 31st Street in Little Village, owned by Hilda Cortez, has been subject to several concerning patterns over the past seven years. The building, constructed in 1927, currently has seven unresolved building code violations recorded in 2026, with multiple complaint-driven inspections noted primarily in June 2021. This suggests ongoing compliance issues that have not been addressed satisfactorily. The property has also generated multiple service requests, including a building violation complaint and a leak check in May 2026, both of which were resolved through municipal channels. Other documented incidents include an abandoned vehicle complaint in March 2025 and a graffiti removal request in October 2024, both of which were closed successfully.

How 4049 W 31St Chicago'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.

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
