854 Amsterdam Avenue, Manhattan, NY 10025

854 Amsterdam Avenue is a 5-story, 8-unit Old Law Tenement building located in the Upper West Side and owned by Christopher Orpheus. The 125-year-old property has experienced recurring maintenance issues over recent years, with the most significant concerns emerging between 2023-2024. Most recently, there were complaints in November 2024 regarding plumbing (toilet), mold (unsanitary condition), and wall paint/plaster issues, with one plumbing complaint remaining unresolved following a failed HPD inspection attempt.

Earlier in 2023, the building dealt with multiple issues including a fire escape safety inspection, heat/hot water problems, and window frame violations that resulted in issued violations. The building's infrastructure has shown persistent challenges, with emergency heat/hot water issues reported in both 2023 and 2025. Historical data reveals a pattern of maintenance concerns, including multiple instances of mold, wall damage, and heating problems.

Of particular note are the building's rodent inspections, with several baiting operations conducted between 2022-2023, though recent inspections in 2023 and 2024 showed improvements with "Passed" results. The building has demonstrated good pest control practices, with no recorded bedbug infestations since 2019, and the most recent 2024-2025 filings show no evidence of current infestations. Recent building maintenance has included addressing various violations, such as repairs to broken locks and self-closing door mechanisms in 2023, suggesting some responsiveness to regulatory requirements. The building's age and location have likely contributed to its ongoing maintenance needs, though recent service requests have generally been addressed, with most complaints resulting in either inspections with no violations or being marked as closed following interventions.
