Unlock complete reportLocated at 4436 N Marmora Ave in Chicago's Portage Park neighborhood, this three-unit residential building constructed in 1925 has been owned by Irena Twarowska. Over the past seven years, there have been notable building code violations and service requests, with the most significant cluster occurring in early 2025. Six complaint-driven inspection violations were recorded and subsequently resolved in January and September 2025, indicating that the issues were addressed, though the specific nature of these violations is not detailed in the records. More recently, in 2026, there were several service requests, including plumbing-related issues with both water concerns on the street and a leak check in May, as well as an alley pothole complaint and two abandoned vehicle complaints in April of the same year. While these incidents reflect some ongoing maintenance and infrastructure challenges in the vicinity of the property, it's worth noting that all documented violations and service requests have reached a closed status, suggesting that the issues were addressed through proper channels. The building's total record of 11 violations and 14 service requests over seven years shows a pattern of both building and neighborhood-related concerns, though the majority of violations have been resolved through proper channels.

How 4436 N Marmora 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.
