Unlock complete reportThe two-unit residential building at 4931 W Thomas Street in Chicago's Austin neighborhood is a 1923 structure currently owned by Albert A Rosario. Over the past seven years, there have been minimal documented interactions with city services, with only two recorded 311 service requests. The most recent incident occurred in February 2026, classified as an information-only call to 311 City Services, which suggests it was likely not related to building conditions or resident services. Prior to that, in August 2024, there was a report of an injured animal, which was also routed through the 311 City Services system and subsequently closed. Both incidents appear to be relatively routine in nature and not directly related to the building's condition or resident services.

How 4931 W Thomas 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
