Unlock complete reportThe two-unit residential building at 4150 W School St in Chicago's Irving Park neighborhood, owned by Carlos Quito, has a complex history of maintenance and quality-of-life issues over the past several years. Built in 1923, the property currently faces multiple unresolved concerns, with five open code violations recorded between 2022 and 2024, primarily resulting from complaint-driven inspections. The building's recent service history shows a concerning pattern of issues requiring municipal intervention, with 15 service requests filed through 311 over the past seven years. While seven of these requests were for abandoned vehicle complaints (six of which were closed out between January and February 2026), other serious issues have been reported, including a no water complaint in November 2025 and a rodent infestation complaint in January 2026. The only building permit recorded during this period was related to a resolved permit-related inspection in March 2021, suggesting limited recent investment in building improvements. Historical data shows an environmental complaint regarding air pollution dating back to April 2007, though this appears to be an isolated incident in the building's record. The combination of multiple open violations, recurring service requests, and limited permit activity suggests ongoing maintenance and tenant comfort challenges within the property.

How 4150 W School St 1'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 3731 buildings in this neighborhood, 3507 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
