4521 S Hermitage Ave 1
Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. 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 New City average of 1.5.
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 three-unit residential building at 4521 S Hermitage Ave in Chicago's New City neighborhood, owned by George Cardoso, is a historic structure dating back to 1888. The building has experienced several municipal interactions over the past couple of years, with the most recent being a water lead test kit request that remains open as of November 2025. This request is particularly significant from a health and safety perspective, suggesting ongoing concerns about water quality in the building. The property has also faced some basic service maintenance issues in 2025, including low water pressure (July), and requests for blue recycling cart and garbage cart maintenance (both in August), though these matters have since been resolved. The building's permit history is minimal, showing only one building permit in the past seven years, while the total number of 311 service requests made by the owner in this period stands at six, with four of these requests originating from the unit itself. The relatively few number of service requests and permits over the past seven years could indicate either a stable building condition or limited reporting of issues, though without more context it's difficult to draw definitive conclusions about the property's overall condition.

How 4521 S Hermitage Ave 1'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 4198 buildings in this neighborhood, 3148 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
