Unlock complete reportThe two-unit residential building at 3016 N Mason Ave, owned by Alejandro Mendoza and located in the Belmont Cragin neighborhood, has a mixed record of maintenance and compliance since its construction in 1951. Of particular note, in June 2022, six complaint-driven inspection violations were documented, though all were subsequently resolved. These violations from mid-2022 represent the most significant cluster of issues on record, but it's worth noting that there have been no building code violations recorded in the past year and a half. The property has experienced some service-related challenges, with a total of four 311 service requests in recent years. These include a rodent baiting complaint and garbage cart maintenance issue in 2025, a blue recycling cart request in July 2024, and a building violation report in May 2024, all of which have been closed. While the building has had its share of issues, particularly in mid-2022, the prompt resolution of violations and lack of recent building code violations may suggest improvements in maintenance practices, though ongoing attention to service issues like rodent control and garbage management appears necessary based on the service requests over the past two years.

How 3016 N Mason Ave 1's risk score is calculated

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
