Augrented Insights Report for 624 Riverdale Avenue

As of July 2025, 624 Riverdale Avenue is a three-story, six-unit residential building constructed in 1930 and currently owned by Michael Slochowsky. The property has experienced persistent maintenance and safety issues in recent months, with multiple violations and complaints. In April 2025, there were rat sightings reported, and as of June 2025, there were ongoing concerns with rodent activity that resulted in failed inspections.

The building's heating and water systems have been problematic, with violations cited in 2025 regarding heating issues, and previous complaints in 2024 and 2025 indicating both building-wide and individual apartment hot water problems. Multiple housing maintenance code violations remain open from 2024, including issues with the boiler system, building entrance door, and various repair needs throughout the building. The Department of Buildings records show several active violations related to safety systems and structural maintenance, including an active ECB violation from 2023 regarding a roof parapet wall issue and a broken boiler igniter violation from late 2024.

There are significant concerns regarding the building's maintenance history, with recurring violations related to external inspections, building facade conditions, and safety compliance issues. The property has a documented history of failed rodent inspections, with recent activity showing continued evidence of infestation. While there have been no bedbug reports in the past four reporting periods (2020-2024), the building's overall maintenance record shows persistent challenges with both basic systems and preventative maintenance compliance, particularly regarding heating, water supply, and pest control.
