Unlock complete reportThe two-unit residential building at 1911 S Jefferson St in Chicago's Lower West Side, owned by Mary Lockard, presents a concerning pattern of unresolved building code violations and a series of maintenance-related service requests. Most notably, there are currently six open building code violations as of May 2025, all stemming from complaint-driven inspections conducted in 2024-2025, indicating persistent issues that have not been rectified. The property has also experienced multiple instances of graffiti, with four removal requests filed between February and March 2026, all of which have been resolved. Additionally, there was one garbage cart maintenance request and an abandoned vehicle complaint in May 2025, both of which were closed, along with a resolved violation regarding an unpermitted construction activity in March 2026. Given the age of the building (constructed in 1888) and the relatively small number of units (2), the concentration of recent violations and service requests, particularly the current unresolved building code violations, suggests ongoing challenges with property maintenance and regulatory compliance.
How 1911 S Jefferson 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
