Unlock complete reportThe two-unit residential building at 5401 W Sunnyside Ave in Portage Park, owned by Caryl W Singer, has been in existence since 1955 and has generated 16 service requests to the city over the past seven years. The building's most recent service requests, dating from 2025 to 2026, have primarily concerned street-related issues, with three reports of potholes (two in 2026 and one in 2025), suggesting ongoing transportation infrastructure challenges in the immediate vicinity. Additionally, there was one sewer-related incident requiring inspection in August 2025, and two abandoned vehicle complaints in the summer of 2025 (one reported to the Alderman's office and the other through 311 City Services). A parking code enforcement review was also conducted in July 2025, though the outcome of this request is not specified in the available records. The service request history indicates that while the building itself has not generated significant internal complaints, there have been notable external infrastructure and parking-related issues in the surrounding area.

How 5401 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.
Out of 3924 buildings in this neighborhood, 510 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
