Unlock complete reportThe two-unit residential building at 1110 N Mason Avenue in Chicago's Austin neighborhood, owned by Louis E Nevels, was constructed in 1922. The building's documented history over the past seven years shows minimal official violations, with only one building code violation recorded in April 2020 related to permit inspection requirements, which remains unresolved as of October 2023. The property has generated ten 311 service requests during this period, with a noticeable cluster of activity in June 2026, including three dead animal pick-up requests, a garbage cart maintenance issue, and an abandoned vehicle complaint, all of which remain open. While there was one previously closed service request for dead animal pick-up in May 2026 and another garbage cart maintenance request from the same month that is currently open, the frequency of service requests in Spring/Summer 2026 suggests ongoing maintenance and sanitation concerns in the immediate vicinity of the building. The single open building code violation and the pattern of service requests related to garbage maintenance and animal control could indicate potential challenges with property upkeep and neighborhood sanitation, though these issues appear primarily related to external rather than internal building conditions.

How 1110 N Mason Ave'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 7212 buildings in this neighborhood, 5553 are predicted to be safer.
