Unlock complete reportThe six-unit residential building at 123 N Jefferson in Chicago's West Loop, owned by Jefferson Randolph, has maintained a relatively clean record since its 1903 construction, with only 15 service requests and three building permits filed over the past seven years. The property's most recent activity has been concentrated in 2026, with three consecutive pothole complaints in January-February, which were all promptly addressed and closed by the Chicago Department of Transportation. A notable incident occurred in 2025 when the building was cited for a house share prohibition violation, though this does not appear to have been repeated in subsequent years. Other service requests over the past two years have included a graffiti removal request, a street light outage, and a report of an abandoned vehicle, all of which were successfully resolved. The building's permit activity has been minimal, with only three permits filed in the past seven years, though the specific nature of these permits is not detailed in the available records.
How 123 N Jefferson 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.
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
