Augrented Insights Report for 1670 3rd Avenue

The 16-unit, 5-story Old Law Tenement building at 1670 3rd Avenue in the Upper East Side, owned by Ken Konfong, has experienced several recurring maintenance issues since 2020, with one of the most concerning patterns being problems with heat and hot water systems. The most recent incidents include a building-wide water supply issue in October 2024 and a heat/hot water problem affecting the entire building in December 2023, both of which were classified as emergencies and resulted in HPD inspections that couldn't be completed due to access issues.

The building has also faced electrical problems, specifically involving outlets and switches in August 2021, and had multiple complaints regarding unsanitary conditions related to garbage/recycling storage in 2020. Recent building history shows attention to pest control, with the most recent bedbug report for 2025 showing no infestations, maintaining a trend of zero infestation cases reported since 2019, except for a single instance in 2019 with three units affected. The building's rodent inspections have generally been successful, with only one failed inspection in October 2023.

The building had multiple violations in the past related to bedbug reporting requirements between 2020-2023, and specific repair issues affecting apartment 1D's radiator and intercom system in late 2020, though most violations have been closed. Additionally, the building underwent two Local Law Audits (2023-2024) and had an illegal hotel room complaint in 2019 that was unable to be verified. Regular maintenance and inspection patterns suggest ongoing oversight, though the recurring nature of heat and water-related issues indicates a persistent infrastructure challenge within this century-old building.
