509 West 135th Street, Manhattan, NY 10031

The five-story, 15-unit building at 509 West 135th Street in Hamilton Heights, owned by Larry Hirschfield and built in 1910, currently shows several ongoing maintenance challenges. Most pressing is a recent heat/hot water complaint filed in May 2025 that remains open. The building experienced multiple ceiling paint/plaster issues in May 2025, with at least two separate complaints leading to violations.

Pests appear to be an ongoing issue, with multiple complaints about unsanitary conditions recorded in May 2025. Apartment 2A has several open violations from a December 2024 inspection, including missing smoke and carbon monoxide detectors, pest infestation, and various maintenance issues such as a defective bathtub glaze and door problems. The building has a history of mechanical system concerns, particularly with the boiler.

There are active ECB violations from 2021 and 2019 related to boiler operation and maintenance, with significant penalties imposed. A pattern of rodent activity has been documented, with multiple inspections showing rat presence between 2023-2024, though a recent May 2025 inspection passed. Other building issues have included problems with doors, windows, and electrical systems as evidenced by multiple 311 complaints and HPD violations throughout 2025. While there have been numerous complaints and violations over the years, the building has consistently complied with bedbug reporting requirements, showing no documented infestations since 2020.
