Unlock complete reportThe three-unit residential building at 2900 N Mason Ave in Belmont Cragin, owned by Wayne Bruner, has been standing since 1959 and has generated a total of five documented 311 service requests over the past seven years. The most recent activity on record includes a rodent baiting/rat complaint from August 2025, which represents the most significant recent health and safety concern. Prior to this, the property experienced a series of relatively minor issues in 2024, including a graffiti removal request in September, a parking code enforcement review also in September, and an abandoned vehicle complaint in July, all of which have since been resolved. While these incidents indicate some maintenance and compliance challenges, it's worth noting that the frequency of complaints appears to have decreased in recent months, with no recorded service requests in 2023 through October 2023. The building's service request history suggests typical urban neighborhood issues, with a mix of property maintenance (graffiti removal) and municipal compliance (parking enforcement) matters, though the most pressing concern remains the recent rodent issue.

How 2900 N Mason Ave 1St'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 4453 buildings in this neighborhood, 2004 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
