Unlock complete reportThe property at 5314 S Blackstone Ave is a three-unit residential building located in Chicago's Hyde Park neighborhood, constructed in 2021 under the ownership of John Gruszka. The building's records show remarkably low activity for its short history, with only one 311 service request on record since 2021, which was for a recycling pickup in December 2025, representing the building's first known service request. The owner, John Gruszka, who holds three parcels in total, has had 18 service requests recorded across these properties in the past seven years, though it's noteworthy that none of these requests appear directly related to the Blackstone Ave address itself. The building's relatively recent construction date, combined with the minimal service request history specific to this address, suggests that the property has experienced no significant maintenance issues or resident concerns warranting official reporting through the 311 system to date.
