Unlock complete reportThe three-unit residential building at 2307 N Mason Ave 2 in the Belmont Cragin neighborhood, owned by Luis A. Ortega and constructed in 1923, has had a total of 17 service requests registered with the city's 311 system over the past seven years, all of which were made by or are attributable to the owner. The most recent activity includes an open sidewalk inspection request filed in March 2026, while earlier in the same year, there were two separate garbage cart maintenance requests in February. Prior issues that have since been resolved include an abandoned vehicle complaint in December 2025, a parking code enforcement review in October 2025, and a street pothole complaint in August 2025. The building's service request history shows a relatively low frequency of issues, though the open sidewalk inspection request may warrant attention from a resident safety perspective.

How 2307 N Mason Ave 2'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 4437 buildings in this neighborhood, 3416 are predicted to be safer.
