5480 S Cornell Chicago
Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.
This building has 0 building violations (7y), at or below the Hyde Park average of 5.3.
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 157-unit residential building at 5480 S Cornell in Chicago's Hyde Park neighborhood, owned by Marian Rachowicz, has been standing since 1923. Over the past seven years, the property has experienced a relatively low volume of service calls, with only 12 311 Service Requests filed, along with just one building permit application during this period. The most recent service requests in 2026 show a concerning pattern of building-related issues, including two building violations (in May and November), though it's worth noting these were resolved, as indicated by their closed status. Other service requests from 2025 and 2026 included a water on street complaint, a tree emergency, graffiti removal, and a general information call. The historical data suggests that while the building has had some maintenance and safety issues requiring municipal intervention, most of the problems have been dealt with promptly through normal city service channels. The frequency and nature of recent building violations and water-related complaints, while relatively few in number, are worth noting as the most significant recent events on record for this property.

How 5480 S Cornell Chicago'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 417 buildings in this neighborhood, 409 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
