Initial analysis

The two-unit residential building at 145 W 71st Street in Chicago's Grand Crossing neighborhood, owned by Dorothy M Harris, has experienced several concerning issues over the past few years. Most notably, there is an open building code violation from November 2019 that remains unresolved. The property has faced recurring water-related problems, with three documented water-related service requests in 2025 alone, including a water-on-street complaint and a water-in-basement complaint. Additionally, there were two sewer cleaning inspection requests made in mid-2025, suggesting ongoing drainage or plumbing issues. The building has also been subject to two building violation complaints in 2024 and 2025, though records indicate these were closed. While there has been only one building permit filed in the past seven years, the pattern of service requests, particularly regarding water and sewer issues, may impact resident comfort and building maintenance.

Risk rating

How 145 W 71St St'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.

Neighborhood percentile
27thpercentile
