Unlock complete reportThe two-unit residential building at 5511 N Monitor Ave in Jefferson Park, owned by Brenda O'Donoghue, has been undergoing regular maintenance and dealing with environmental challenges in recent years. Built in 1923, this property has generated a total of 11 service requests over the past seven years, with the most recent activity focusing heavily on tree-related issues. In 2026 alone, there were two reported instances of tree debris cleanup, following a pattern established in 2025 which saw multiple similar requests including a tree emergency response in May of that year. The building's maintenance needs have also extended to its waste management infrastructure, with two requests for garbage cart maintenance recorded in 2025. A sidewalk inspection request was submitted earlier this year and remains open, representing the only current unresolved issue on the property’s service request history. While the frequency of service requests suggests regular maintenance activity, the clustering of tree-related incidents and waste management requests indicates these areas may require ongoing attention.
How 5511 N Monitor 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 1617 buildings in this neighborhood, 954 are predicted to be safer.
