8221 S Ellis 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 Chatham average of 4.2.
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 16-unit residential building at 8221 S Ellis in Chicago's Chatham neighborhood, owned by Ellis Apt LP, has a documented history dating back to its construction in 1926. Over the past seven years, there have been four recorded 311 service requests associated with the property, all of which have been resolved and marked as closed. The most recent and most significant recorded incident was a building violation in December 2025, which appears to be the only structural or safety-related issue on record. The property has experienced some animal-related incidents, including a stray animal complaint and an animal in trap complaint, both occurring in late 2025, though these incidents are unlikely to directly impact resident safety or building conditions. The only other documented interaction with city services was a general information request in May 2025. While the building's recent service request history is relatively minimal, with only four total incidents over seven years, it's worth noting that three out of the four recent incidents in 2025 were related to animals rather than building-specific issues.

How 8221 S Ellis 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 1901 buildings in this neighborhood, 1692 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
