Augrented Insights Report for 457 Classon Avenue

The three-story, five-unit building at 457 Classon Avenue in Bedford-Stuyvesant, owned by Clive Knight and constructed in 1931, has experienced significant maintenance challenges over the past two years. The most pressing issues involve recurring electrical problems, with multiple reports of power outages and no lighting between 2023 and 2024. The building has also faced several heating and hot water system failures, particularly problematic during winter months, though some complaints were resolved promptly.

A concerning pattern of rodent activity has been documented through multiple inspections from 2023 to 2025, indicating persistent pest control challenges. The property currently has several open violations requiring attention, including failure to file required annual bedbug reports and various building code compliance issues from 2023. These violations pertain to self-closing doors in multiple locations, including the building entrance, basement, and between hallways, as well as locked access issues to the heating system.

The building's boiler maintenance documentation appears to be in disarray, with violations spanning multiple years (2019-2024) for not filing required external low-pressure inspection reports, resulting in an active $625 penalty. Recent inspections in 2024-2025 have continued to show rat activity, though bait was applied in 2023. The Department of Buildings previously responded to an emergency egress complaint in October 2023 and found no violations at that time.
