Initial analysis

The four-unit residential building located at 1734 W 35th Street in the McKinley Park neighborhood, owned by LYONS 1734 W 35TH LLC, is an 1882 construction that has experienced several concerning issues over the past seven years. Most notably, there is an ongoing pattern of unresolved building code violations, with six complaint-driven inspections recorded in March 2026 and two additional violations from May 2023 that remain open. The building's service request history shows 19 incidents, including a recent graffiti removal request in May 2026 and multiple building violations in February 2026, two of which were plumbing-related and successfully resolved. The property has also faced environmental scrutiny, evidenced by an air pollution complaint in October 2025 that was investigated but found to have no violations. Despite these numerous complaints and violations, there has been only one building permit filed in the past seven years, which may raise questions about proper maintenance and upkeep. The most recent data suggests a pattern of recurring issues, particularly in early 2026 when multiple violations and service requests were concentrated.

Risk rating

How 1734 W 35Th 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.
