Initial analysis

The two-unit, 1924 residential building at 4957 W Sunnyside Ave in Portage Park, currently owned by Christopher Pietrusiew, has had a relatively quiet record over the past seven years, with only two building permits filed during this period. The property has generated seven 311 service requests since 2024, with the most recent being a water-related issue on the street in April 2026 and a fly dumping complaint in February 2026. Other notable service requests include a street light pole damage complaint in August 2025 and a report of an injured animal in March 2025. There is currently one open request from January 2025 regarding the Shared Cost Sidewalk Program, which may indicate potential infrastructure upgrades. While these service requests have all been closed except for the sidewalk-related one, it's worth noting that they primarily relate to public infrastructure and street-related issues rather than problems directly affecting the building itself. The property's documented history suggests regular maintenance of major systems, as evidenced by the limited number of building permits and service requests directly connected to the structure.

Risk rating

How 4957 W Sunnyside 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.
