511 West 135th Street, Manhattan, NY 10031

The five-story, 21-unit building at 511 West 135th Street in Hamilton Heights, currently owned by Mariel Arismendy, has experienced numerous maintenance issues in recent years, particularly between late 2023 and 2024. The property has a recurring pattern of water-related problems, with multiple complaints about leaks ranging from heavy flow to slow leaks, with the most recent water leak complaint filed in December 2024.

Between April 2024 and December 2024, significant issues were documented, including heating problems (both building-wide and apartment-specific), ceiling and wall damage requiring plaster and paint repairs, and unsanitary conditions involving mold. The building has also faced challenges with rat activity, evidenced by multiple inspections between 2023 and 2025 showing consistent rodent presence, though the most recent inspection in May 2025 resulted in a "Passed" status. Several building code violations were identified and subsequently addressed, including a problematic lock on a fire escape window in Apartment 5A, visible mold in the 5A hallway, roof leakage affecting the 5A hallway ceiling, and various maintenance issues in Apartment 4D that required attention.

The property has shown compliance with bedbug reporting requirements over multiple years, consistently reporting zero infested units. While many violations have been closed through corrective action, there remain some open violations as of the last inspection dates, including issues with vestibule door self-closing mechanisms. The building's maintenance history suggests ongoing challenges with basic systems such as heat and water, though recent improvements in rodent control were noted in the latest inspections.
