Unlock complete reportThe six-unit residential building located at 8411 W Bryn Mawr Ave in the O'Hare neighborhood was constructed in 1973 and is currently owned by Spero Margaris. The property has experienced relatively minimal service requests over the past seven years, with a total of 11 requests specifically related to the building itself, compared to 22 requests associated with all three parcels owned by Margaris. The building's documented service requests show the majority of recent issues have been related to traffic and street infrastructure, rather than the building's internal conditions or systems. In 2026 alone, there have been multiple reports of traffic signal problems, with two open complaints and one closed complaint, as well as a street light pole damage report that has since been resolved. Prior to this, in 2025, there were two infrastructure-related requests that were addressed: one for sign repair and another for tree trimming, though it's worth noting that tree trim requests are no longer being accepted. The building's service request history suggests that while there have been various maintenance and infrastructure issues in the vicinity of the property, there are no recent records of internal building complaints that would indicate significant resident experience or safety concerns.

How 8411 W Bryn Mawr Ave 1Stfl's risk score is calculated
