Unlock complete reportThe 13-unit residential building at 235 N Mason in Chicago's Austin neighborhood, owned by Gabriel Nicolescou, has been subject to multiple regulatory oversight events over the past seven years. Most notably, there are currently four unresolved building code violations from a December 2023 periodic routine inspection, as well as one unresolved violation from a March 2023 complaint-driven inspection. The building had two periodic routine inspection violations in July 2022, though these were resolved satisfactorily. The property has experienced a consistent pattern of plumbing-related issues, as evidenced by two separate plumbing violation complaints made in July and August 2024, both of which were resolved by October 2024. Additional maintenance and service requests include a no-water complaint from October 2024, which was also closed. While there are two outstanding inspection violations as of December 2023, the building has had relatively few permitted modifications in recent years, with only one building permit recorded in the past seven years. Outside the building's direct condition, two tree planting requests were made and closed in May 2024, though these are not directly related to the building's structural or habitability issues.

How 235 N 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
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, 7151 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
