Unlock complete reportThe three-unit residential building at 1123 W Pratt Blvd in Rogers Park, owned by Robert M Gross and constructed in 1915, has had a relatively uneventful history over the past several years, with most recent issues concentrating on water-related concerns. In early 2026, the property experienced multiple water supply problems, with three documented complaints about low water pressure or lack of water, though all these complaints have been formally closed. Additional maintenance issues have been reported and resolved, including a snow-uncleared sidewalk in January 2026 and a street pothole complaint in January 2026. The building's only environmental complaint on record pertains to an air pollution incident from 2012, which was investigated but resulted in no confirmed violations. Interestingly, there is currently an open request from August 2025 for a water lead test kit, which suggests ongoing concerns about water quality at the property. Despite these issues, it's worth noting that the building has only generated ten total 311 service requests over the past seven years, which is relatively modest for a three-unit multi-family residence.
How 1123 W Pratt Blvd 1'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 1536 buildings in this neighborhood, 814 are predicted to be safer.
