9037 S Exchange Ave
A handful of records on file over the last seven years, and our model predicts a high risk of further maintenance problems in the next 12 months. A few records worth reading before you sign. Check whether they were closed out, and ask what was actually fixed.
This building has 2 building violations (7y), at or below the South Chicago average of 2.9.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe two-unit residential building at 9037 S Exchange Ave in Chicago's South Chicago neighborhood, owned by Efigenia Perez, has a documented history dating back to its construction in 1893. The property has experienced relatively few issues in recent years, with only two building code violations recorded in the past seven years: one in November 2021 that was resolved and another, as of December 2021, which remains open and unresolved. The building has generated 20 service requests through the city's 311 system over the past seven years, with the most recent three requests (from October 2025) relating to multiple tree planting requests that are still open. Other notable service requests include a rodent baiting complaint from July 2025 (now closed), a stray animal complaint from December 2025 (closed), and a sign repair request from March 2026 (currently open). The property has required minimal intervention in terms of building permits, with only two recorded in the same seven-year period. While the number of service requests is relatively high for a small building, most of these appear to be related to exterior maintenance and urban infrastructure rather than internal building issues.

How 9037 S Exchange 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
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 2611 buildings in this neighborhood, 2193 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
