Unlock complete reportThe three-unit residential building at 5720 W Belmont Ave in Portage Park, owned by Zak Lenczowski, is a 1931 structure that has experienced minimal documented issues over the past seven years. The property's records show only one building code violation during this period, which remains unresolved as of May 20, 2020, representing the most significant outstanding concern affecting the property. Additionally, there have been 19 service requests filed through the 311 system, with the most recent two (from March 2026) related to finance and parking code enforcement, both of which have been resolved. The service request history includes a mix of neighborhood concerns, including an open sidewalk inspection request from September 2025, and several resolved issues such as an alley light outage, an abandoned vehicle complaint, and a tobacco-related concern, all from August-September 2025. While the number of service requests is notable, most appear to be community-related concerns rather than direct building issues, with only one building code violation on record specifically pertaining to the property's condition.

How 5720 W Belmont 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, 3610 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
