842 Amsterdam Avenue, Manhattan, NY 10025

The five-story, 14-unit old law tenement building at 842 Amsterdam Avenue, owned by Kazuhiko Kyogoku and constructed in 1925, has experienced several significant issues in recent years, particularly relating to heat and sanitation. The most pressing current concern is an open complaint about unsanitary conditions and pests filed in December 2024, which remains unresolved as of July 2025. There has been a pattern of heat and hot water issues throughout the building, with multiple complaints documented between December 2023 and November 2024.

These complaints, while often resolved quickly, indicate a recurring problem with the building's heating system. The building has maintained a bedbug-free status for the past several reporting periods from 2019 to 2024, with no infested units reported in the last eight filings. The property has faced structural and safety challenges, particularly highlighted by violations from 2018 regarding damaged wood floors and stair treads in public areas, especially at the 4th and 5th stories.

Current open violations from 2021 relate to building safety systems, including issues with smoke detectors and balcony fire escape access that have not been fully resolved. Recent rodent activity has been documented through multiple inspections in late 2024, with bait applied in several instances between November and December 2024, although October 2023 showed a passing compliance result. The building's ventilation systems have also faced scrutiny, with an active violation noted in 2023 for failure to file the 2022 external low-pressure inspection. While the property has processed various complaints through the Department of Buildings regarding egress issues and fire safety concerns, many of these have been resolved or dismissed, including a notable ECB violation in 2021 regarding a restaurant's outdoor dining setup blocking a fire escape.
