Unlock complete reportThe three-unit residential building at 1427 W Gregory Street in Chicago's Andersonville neighborhood, owned by KDL Properties Inc and constructed in 1917, has experienced several notable issues over the past seven years. The property has a concerning pattern of permit-related violations, with five citations recorded between 2019 and 2020, of which two remain unresolved while three have been resolved. The building's maintenance record shows attention to external environmental management, including recent tree-related service requests, with the most recent open requests for tree removal and sidewalk inspection created in 2026. There have been multiple tree trim requests in April 2025, though these were noted as no longer being accepted. The property has also faced some urban environmental challenges, as evidenced by a closed rodent baiting complaint in 2024 and a graffiti removal request in 2025, which was successfully addressed. While the building has accumulated some service requests and violations, it's worth noting that the majority of these issues have been resolved through proper channels, though the open permit violations warrant attention. The property's history includes a valid noise complaint from 2016, which was resolved by the end of May 2016.

How 1427 W Gregory 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 680 buildings in this neighborhood, 639 are predicted to be safer.
