Augrented Insights Report for 509 West 134th Street

509 West 134th Street is a 5-story, 19-unit New Law Tenement building located in Harlem, constructed in 1905 and currently owned by Nathan Obstfeld. The property has experienced recurring maintenance issues, particularly with water systems and heating. In 2025 alone, there have been three significant water-related complaints (one slow leak and one heavy flow issue) and an ongoing electrical lighting problem.

Previous heating and hot water-related incidents have been a persistent concern, with multiple complaints across 2022-2023 affecting both individual apartments and the entire building. Notably, apartment 3C had violations for excessive hot water temperatures and door issues in late 2023, while violations from 2021 documented various safety and maintenance problems in apartment 1C, including heating, lighting, and smoke detector issues. The building's infrastructure has faced critical challenges, particularly regarding the boiler system, with significant violations recorded in 2019 related to defective equipment and unauthorized work, resulting in multiple fines.

Recent inspections (2025) have indicated rat activity, though previous pest control measures (bait application) were implemented in 2023. The property has demonstrated some compliance with bedbug reporting requirements, showing no infested or re-infested units in the past three reporting periods (2022-2024). Additional building maintenance records from 2023-2024 show various plumbing and sanitary issues being addressed, though many complaints remain open as of current records. While some historical violations from 2019-2023 have been dismissed or resolved, the frequency of recent maintenance issues suggests ongoing challenges with building systems and infrastructure.
