3257 S Aberdeen St
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 Bridgeport average of 1.0.
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 3257 S Aberdeen St in Bridgeport, owned by Zhou Zhen Ni, is a well-established property dating back to 1888. The Chicago Master Building Record shows minimal recent activity, with only three documented 311 service requests in the past seven years, all of which occurred in 2025. These requests were for relatively minor issues including a missed garbage pick-up in February, garbage cart maintenance in June, and a report of an injured animal in December, all of which have since been closed. The limited number of service requests and their nature suggests that there have been no significant ongoing maintenance issues or safety concerns at the property. The building's ownership and service request history indicates stable management, with the three service requests representing only a small fraction of the total interactions typically seen in urban residential buildings.

How 3257 S Aberdeen 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.
Out of 3132 buildings in this neighborhood, 2474 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
