Unlock complete reportThe six-unit residential building at 8540 W Gregory St in the O'Hare neighborhood, owned by Marie Mietus, has been in operation since 1968. Over the past seven years, the property has generated three documented 311 service requests, all of which were recorded and closed in 2025. The nature of these requests varied, including a tree trimming request that is no longer being accepted, a sanitation code violation, and an ice and snow removal request. While all issues have been officially closed, it's noteworthy that all documented service requests occurred within a concentrated period in 2025, representing the entire record of 311 interactions for this building over the past seven years. The property's limited history of service requests could indicate either proactive maintenance or minimal service needs, though the single year cluster of requests in 2025 warrants attention as the most recent building interaction on record.

How 8540 W Gregory St Gflat'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.
