303 Amsterdam Avenue, Manhattan, NY 10023

The three-story, four-unit building at 303 Amsterdam Avenue in the Upper West Side, owned by Charles Yassky and constructed in 1900, has experienced several significant issues over the past few years. Most notably, between 2021 and 2024, there were multiple rodent-related incidents documented through both 311 service requests and Department of Health inspections, with the most recent rodent inspection in June 2024 resulting in a "Passed" rating.

The building also faced regulatory scrutiny in 2022 when it was cited for several violations related to unauthorized modifications and illegal occupancy, including the installation of partition walls creating additional rooms and plumbing for a residential sink, as well as the operation of an unlicensed physical treatment establishment (Huana Spa) on the second floor in violation of zoning regulations, though these particular violations have since been resolved. The property has maintained compliance with bedbug reporting requirements since 2021, consistently reporting zero infested, eradicated, or re-infested units in its annual filings through 2025.

While the building has faced multiple housing maintenance code violations regarding bedbug report filings between 2021 and 2024, these appear to have been administrative in nature. The building's rodent control efforts have shown a pattern of both bait application and activity detection between 2021 and 2023, with the situation appearing to stabilize somewhat in 2024 based on the most recent inspections. The property maintains a "HERETOFORE CONVERTED CLASS A" designation, indicating it has undergone some form of prior conversion from its original use, likely related to its current four-unit configuration.
