Initial analysis

The three-unit residential building at 3936 N Linder Ave in Chicago's Portage Park neighborhood is owned by Eric J. Schwarz and was constructed in 1925. The property has a relatively low volume of 311 service requests over the past seven years, with a total of eight recorded incidents. The most recent service request, filed in June 2026, is an open complaint regarding an abandoned vehicle, while three other calls relate to e-scooter parking complaints (one of which remains open). Two street cleaning requests were submitted in July and November 2025, both of which were successfully resolved. Additionally, there was one information-only call in April 2026 that was closed. The service request history suggests most issues have been minor and typically related to street maintenance and urban mobility concerns rather than building-specific problems, with all except one being resolved through normal city services.

Risk rating

How 3936 N Linder Ave'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.
