520 West 48th Street, Manhattan, NY 10036

520 West 48th Street, a 7-story, 109-unit residential building constructed in 2002 and currently owned by David Kramer, has experienced several recurrent maintenance issues over the past two years, with particular attention needed to heating, water supply, and sanitation matters. Most recently in March 2025, the building faced multiple water supply incidents requiring immediate emergency attention by HPD, and there have been persistent heating and hot water issues affecting both individual apartments and common areas throughout late 2024 and early 2025. The building has also contended with mold and pest problems, with inspections in December 2024 revealing unsanitary conditions involving mold and pests, though HPD was unable to complete inspections in some cases.

The property has a documented history of infrastructure and safety concerns, including violations related to self-closing doors and ventilation systems. Specific apartments have been identified with persistent problems: Apartment 2H had noted issues with mold and door functionality as of December 2024, while Apartment 7B reported pest infestation and ventilation problems in late 2024. The building's systems have faced scrutiny, with violations regarding hot water supply systems and door self-closing mechanisms.

Recent rodent activity has been a significant concern, with multiple inspections in 2025 showing rat activity and the need for bait application. The building's management has been subject to investigations regarding illegal hotel room usage, with complaints filed in 2024, though access was denied during inspections. While the property has maintained a clean bedbug report record over multiple reporting periods from 2019 to 2024, the ongoing maintenance issues, particularly regarding water supply and heating systems, suggest continued challenges in building upkeep.
