1020 Amsterdam Avenue, Manhattan, NY 10025
The 10-story, 66-unit New Law Tenement building at 1020 Amsterdam Avenue, owned by Anderson Santos, has experienced recurring water-related issues over the past several years, with recent reports in 2025 and 2024 documenting standing water on the roof and access issues for health inspections. Between May and July 2024, multiple violations were issued by the Department of Housing Preservation and Development (HPD) for water leaks, damp spots, plumbing issues, and problems with walls and appliances.
The building has also faced various maintenance challenges, including a persistent rodent control situation with documented rat activity in 2024, though recent inspections in 2025 show compliance with rodent control requirements. The property has a history of violations requiring attention to building systems and safety compliance, including outstanding elevator maintenance issues (as of 2024) and problems with the building facade noted in active violations from 2024. Multiple batches of housing maintenance code violations were documented in 2024, particularly affecting apartment 2D, which had issues with water leaks, plaster surfaces, and even a recorded pest infestation that was certified as corrected in September 2024.
The building underwent several inspection cycles related to permits and construction work, with some instances of work being performed without proper permits noted in 2023-2024, though permits were subsequently properly issued. Recent environmental monitoring shows a reduction in bedbug infestations, with only two documented cases in 2022-2023, and none reported in 2024-2025. The building's maintenance history shows a pattern of water-related issues, with multiple leak complaints and violations, particularly affecting apartments on various floors.
