Unlock complete reportThe two-unit residential building at 6147 S Mason Ave in the Clearing neighborhood, owned by Camarino Barragan and constructed in 1923, has experienced a series of maintenance and safety issues over the past two years. The most pressing concerns appear to be water-related, with three incidents of basement water issues reported between July and September 2025, and two rodent-related complaints filed in mid-2024. While one water-related complaint from July 2025 has been marked as closed, the status of another water-related complaint from September 2025 remains open. The building has also required attention to its waste management infrastructure, with a garbage cart maintenance request in October 2025, though this issue has been resolved. The clustering of water-related problems, particularly the complaints about basement water issues and the ongoing nature of water quality testing, suggests that moisture management may be an ongoing challenge for this property. Additionally, the presence of rodent complaints, though now resolved according to the records, indicates that pest control has been a prior concern for this building.

How 6147 S Mason 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 624 buildings in this neighborhood, 412 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
