3000 N Mason Ave 1
Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.
This building has 0 building violations (7y), at or below the Belmont Cragin average of 0.9.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe two-unit residential building at 3000 N Mason Ave 1 in the Belmont Cragin neighborhood, owned by Verdelle Widegren, was constructed in 1924 and has had minimal documented service interactions with city agencies over the past seven years. The building's service request history shows six recorded incidents, with the most recent occurring in March 2026 regarding a blue recycling cart, followed by a street pothole complaint and an abandoned vehicle complaint in May 2025. Two significant rodent-related complaints were filed in July 2024, which were notable given their health and safety implications, along with a missed garbage pickup complaint in April 2024 that may have contributed to waste management concerns. All documented service requests have been officially closed, though their resolution details are not specified in the available records. The relatively low number of service requests over this extended period could suggest either good building maintenance or limited reporting of issues.

How 3000 N Mason Ave 1'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, 3651 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
