Initial analysis

The two-unit residential building at 1935 S Jefferson St in the Lower West Side, owned by 1935 Jefferson LLC, has been standing since 1878. In recent years, the property has experienced three building code violations, all of which occurred in February 2020 during permit-related inspections and have been resolved. The majority of documented issues in and around the property relate to street-level concerns rather than the building itself, with a total of eight 311 service requests over the past seven years. These service requests primarily focused on external maintenance matters, including multiple graffiti removal requests (three in May 2026, one in April 2026), a street light outage (March 2026), a pothole complaint (January 2026), and a stray animal report (September 2025). While the building has encountered some code violations, it's noteworthy that these were specifically tied to permit-related inspections and have been officially complied, suggesting attention to regulatory requirements.

Risk rating

How 1935 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

Lower risk — safer than most nearby

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.

Neighborhood percentile
7thpercentile
