Initial analysis

The three-unit residential building at 5145 W Sunnyside Ave in Portage Park, owned by James L Whitlock, was constructed in 1961 and has experienced several documented issues over recent years. The property has generated a total of seven 311 service requests in the past seven years, with the most recent activity occurring in April 2026 involving both a sign repair request and a street-related complaint. While the building itself has no directly reported maintenance issues or safety concerns, there was one rodent baiting complaint filed in August 2024 that was subsequently closed. Notably, there have been multiple street-related complaints in the vicinity of the property, with four separate pothole complaints recorded between January and October 2025, all of which were closed following investigation or repair. The clustering of pothole complaints suggests a period of infrastructure maintenance needs in the immediate area during 2025, though all related service requests have been officially resolved.

Risk rating

How 5145 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.

Neighborhood percentile
48thpercentile
