Unlock complete reportThe two-unit residential building at 4251 N Sacramento Ave in Chicago's Irving Park neighborhood, owned by Hector M Aquino, has been standing since 1917 and has generated a total of five 311 service requests over the past seven years. The most recent activity, as of May 2026, includes a water lead test kit request that remains open, representing the only health-related concern on record and potentially impacting resident safety if lead contamination is confirmed. The building's service request history shows various non-urgent municipal matters, including a dead animal pickup (May 2026), a blue recycling cart request (April 2026), and a pet wellness check (June 2024), all of which were promptly closed. An e-scooter parking complaint was filed in September 2025 and resolved. While the limited number of service requests might suggest minimal issues, the open water lead test kit request warrants attention as the most significant item in the building's recent history.
How 4251 N Sacramento 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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 3714 buildings in this neighborhood, 2080 are predicted to be safer.
