Unlock complete reportThe three-unit building at 2140 W 21st Street in Chicago's Lower West Side neighborhood, constructed in 1888 and owned by Daniel Nieto, has experienced significant recent activity, particularly in 2026. Currently, there are three unresolved code violations resulting from complaint-driven inspections in April and March 2026, representing the most pressing concerns for the property. The building's recent history shows a cluster of complaints and service requests, with five building violations recorded in the past seven years, and notably, 29 service requests associated with the owner during that period. While most of these service requests have been resolved, they indicate ongoing maintenance and safety concerns. In addition to the building violations, the property has generated multiple service requests in 2025-2026, including three abandoned vehicle complaints (January and August 2026), one street light outage complaint (December 2025), and two building violation complaints (March and April 2026). A single building permit was issued in the past seven years, suggesting limited recent improvement work on the property. The combination of unresolved building code violations, multiple recent complaints, and minimal permitting activity warrants attention, though it should be noted that not all service requests necessarily indicate serious issues, as they include routine matters like street lighting and abandoned vehicles.

How 2140 W 21St St'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 3674 buildings in this neighborhood, 2976 are predicted to be safer.
