Unlock complete reportThe two-unit residential building at 1749 N Mason Avenue in Chicago's Austin neighborhood, owned by Irene Domagalski, was constructed in 1923 and has a minimal service record over the past seven years. The property has experienced three documented 311 service requests during this period, with the most recent three requests occurring in late 2025. These recent requests, all closed, pertain to waste management services, specifically a blue recycling cart and garbage cart maintenance, which suggests routine municipal services were required. Of particular note is one complaint filed in August 2025 regarding water service issues, though this complaint was also resolved through the city's 311 system. Given that waste management and water service issues have been documented, this building has experienced some infrastructure maintenance needs, though the relatively low number of service requests over seven years might indicate limited ongoing problems.

How 1749 N 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 7223 buildings in this neighborhood, 867 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
