Initial analysis

The two-unit residential building at 4255 N Narragansett Ave in Chicago's Portage Park neighborhood, owned by J & E Frankowski, has a documented history spanning over seven years with minimal service requests. Built in 1912, this vintage property has only four recorded 311 service requests in recent years, suggesting relatively low demand for municipal services. The most recent requests, filed on June 8, 2026, for blue recycling cart and garbage cart maintenance, remain open as of this report's preparation. These recent service requests follow a pattern established in the summer of 2024, when similar requests were made—though those were successfully closed. Notably, these requests pertain solely to waste management services, with no recorded complaints or issues regarding building safety or resident comfort. The consistent need for waste cart maintenance and recycling services, while indicating active property management, is not unusual for multi-unit buildings in Chicago.

Risk rating

How 4255 N Narragansett 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

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

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