4578 Park Avenue, Bronx, NY 10458

4578 Park Avenue is a 5-story, 16-unit New Law Tenement building located in the Belmont neighborhood, built in 1907 and currently owned by Heng Ly. The building has experienced recurring maintenance issues, with the most recent cluster of complaints in October 2023 involving multiple water leaks (both slow and heavy flow), flooring concerns, and mold conditions, though inspections resulted in no violations for most of these complaints except for one flooring issue. Earlier in 2023, there were also unresolved plumbing issues related to sinks/basins and pest problems, where inspectors were unable to gain access.

The building has active violation citations from the Department of Buildings regarding failure to file external low-pressure inspections for 2018 and 2019, as well as a boiler inspection for 2017. From February to March 2024, several violations were documented and certified, including issues with self-closing doors leading to the rear yard, a mold condition in Apartment 3's bathroom, and problems with the bulkhead ceiling requiring repairs. The building's maintenance history shows persistent challenges, with particular attention needed to moisture-related issues.

It has passed some recent rodent inspections in 2025, though there have been multiple instances of rat activity noted in various inspections throughout 2023-2025. The property has maintained a clean record in terms of bedbug infestations, with no reported cases in the past five years. While some violations have been addressed and certified as closed, including a bathroom threshold repair in Apartment 33 documented in late 2023, the building continues to have open violations as of early 2024 that require attention, particularly concerning the bulkhead ceiling and self-closing door mechanisms.
