Augrented Insights Report for 800 Greenwood Avenue

800 Greenwood Avenue is a 63-unit, 6-story residential building constructed in 1941 and currently owned by Sol Knopf. The building has experienced recurring heat and hot water issues, with nine separate complaints between April and May 2025 documenting loss of these essential services throughout the entire building, though each was resolved promptly with restoration confirmed by occupants during inspections. More recently, in June 2025, there were rodent sightings reported, though the Department of Health and Mental Hygiene subsequently inspected the property and found no violations.

A detailed inspection of apartment 4E conducted in October 2024 revealed multiple violations including missing carbon monoxide detectors and evidence of pest infestations (rodents, flies, and roaches), though these were certified as corrected by November 2024. The building has faced several significant regulatory challenges over the past two years. During 2024-2025, there were three inspections related to building shaking/vibration and structural stability concerns, with one violation issued in October 2023 regarding failure to address immediately hazardous conditions.

Multiple violations were documented between 2023 and 2024 regarding building maintenance issues, including problems with window air conditioner installations, cracked tiles at the entrance, and concerns about self-closing doors to the trash compactor closet on the 6th floor. The elevator system has also been a recurring concern, with violations noted in late 2023 regarding level discrepancies and motor room access. While the building has passed recent rodent inspections (most recently in June 2025), there have been multiple periods of non-compliance in the past, with failures to maintain proper documentation and response to violations being a consistent theme. The property shows some concerning patterns of recurring maintenance issues, particularly regarding heating systems and building envelope maintenance, though many recent violations have been promptly addressed and closed.
