Unlock complete reportThe 39-unit residential building at 6 S Mason in Chicago's Austin neighborhood, owned by Realty Consult Serv In, has been standing since 1929 and has experienced a number of notable events in recent years. Over the past seven years, the property has generated a total of 23 service requests through the 311 system. The most significant recurring issue appears to be plumbing violations, with two documented cases in late 2024 and early 2026, though both were subsequently closed. A notable cluster of service requests occurred in early 2026, with four separate complaints about abandoned vehicles in the vicinity of the property between January and March of that year, all of which were also closed. While these exterior vehicle-related issues and plumbing violations have been addressed through the 311 system, the relatively limited number of service requests over a seven-year period may suggest a generally stable building condition, though this assessment is based solely on available complaint data.
How 6 S Mason 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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 7212 buildings in this neighborhood, 6851 are predicted to be safer.
