Unlock complete reportThe 9100 S Halsted St property is a 4-unit, 1964 building located in Chicago's Washington Heights neighborhood and owned by Rolbert E Harris. Over the past seven years, the building has experienced a relatively high number of incidents, with 22 building code violations and 28 service requests through the 311 system. A cluster of six complaint-driven building code violations occurred on August 4, 2022, though it's worth noting that all these violations were subsequently resolved. The 311 service requests from the past seven years cover various issues, with the most recent complaints (from March 2026) relating to an abandoned vehicle and a stray animal, along with two garbage-related issues and two street light complaints from November 2025. While the volume of service requests and violations is notable, particularly for a small building, the records indicate that violations are generally addressed and resolved when reported. The building's most distant recorded environmental complaint dates back to November 1993, concerning air pollution, though it's unclear whether this was directly related to the building itself or another nearby source.

How 9100 S Halsted 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.

Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
