520 West 134th Street is a 5-story, 24-unit New Law Tenement building in Harlem, constructed in 1910 and currently owned by Miguel Betances. The building has experienced several maintenance issues in recent years, with the most significant problems occurring in 2023-2025. There are multiple open violations related to both plumbing and window issues, particularly in apartment 5A, including problems with window frames, water leaks, and infestation concerns. A series of heating and hot water complaints were recorded in January 2025, affecting both individual apartments and the entire building, though these were subsequently reported as corrected. Regarding building systems, there are active violations for failure to file required low-pressure inspections in 2018, 2019, and 2022, and an April 2022 Environmental Control Board violation remains active concerning various boiler components with a penalty of $3,125. The building has a documented history of rodent inspections, passing consistently between 2018 and 2025, with one failed inspection in December 2023 for unspecified reasons. Bedbug reporting shows no infestations during the 2017-2018 reporting period. While some inspections have resulted in violations, such as for heating systems and window issues, the building has also demonstrated compliance with various housing codes, as evidenced by multiple closed HPD cases. The property has a mix of historical plumbing and heating issues, with particular attention needed regarding the maintenance of windows and addressing active violations related to bedbug reporting requirements as of April 2024.
