Unlock complete reportThe three-unit residential building at 4246 N Mozart St 2 in Chicago's Irving Park neighborhood is a 1924 construction currently owned by John H Costa. The property's record over the past seven years shows minimal activity, with only four documented 311 service requests. The most recent of these, filed in April 2026, remains open and concerns tree debris cleanup. Prior to this, the building experienced typical urban maintenance issues, including an ice and snow removal request in January 2026 (now closed), a closed garbage cart maintenance request from August 2025, and a dead animal pickup request from May 2024 that has since been resolved. Historically, there was one environmental complaint filed in December 2001 regarding illegal dumping, though this incident predates the current owner's management and is unlikely to reflect on current building conditions. The relatively low number of service requests and their nature suggests routine municipal service needs rather than any chronic building-specific issues.

How 4246 N Mozart St 2'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
