4 East 125th Street, Manhattan, NY 10035

4 East 125th Street is a 4-story, 36-unit old law tenement building constructed in 1900, currently owned by Terrence Moan. The building has experienced recurring heat and hot water issues, particularly notable in late 2024 and early 2025, with multiple complaints about inadequate service affecting both individual apartments and the entire building. In addition to these persistent heating problems, there have been documented water leak issues as recently as February 2025.

The property has undergone several emergency rodent control interventions in 2023, with reports of rat activity, though recent inspections in early 2025 passed for rodent presence. There are ongoing maintenance concerns, particularly in Apartment C54, which has multiple open violations from 2024 regarding hot water issues, insect infestation, roof leaks, and plaster damage. The building's entryway security was addressed in October 2024, with violations related to vestibule door repairs and lock mechanisms being properly cited and subsequently closed. The Department of Buildings has recorded several building stability complaints between 2021 and 2024, though inspections generally found no violations.

A concerning pattern of plumbing and water-related issues is evident from recent 311 complaints and Housing Maintenance Code violations, with the most recent water leak complaint documented in March 2025. The building has accumulated three active Environmental Control Board violations related to work performed without proper permits, dating back to 2019, with fines totaling $3,775. The property has a documented history of bedbug infestations between 2019 and 2022, though recent filings (2023-2025) indicate no current infestations. The building's maintenance record shows some improvements, with recent rodent inspections passing, but significant ongoing issues remain, particularly regarding heat and hot water reliability and various apartment-specific maintenance needs.
