463 West 21st Street, Manhattan, NY 10011

The 5-story, 6-unit building at 463 West 21st Street in Chelsea, owned by Magdalena Kosz, has experienced several maintenance challenges over the past few years. The property, which has been classified as a HERETOFORE CONVERTED CLASS A building and dates back to 1836, has had recurring issues with rodent activity, most recently evidenced by multiple bait application inspections in early 2025, followed by a compliance inspection that passed in May 2025.

The building has also demonstrated previous challenges with pest management, as shown by a 2022 violation regarding the failure to file an annual bedbug report, though subsequent filings from 2019 through 2025 indicate no reported bedbug infestations. The Department of Buildings has recorded both violations and active complaints related to the property, notably an investigation in 2018 regarding unauthorized construction modifications to an apartment layout, which resulted in a $200 penalty that has since been resolved. More recently, there is an active complaint from April 2024 regarding Local Law 188/17 compliance inspections, with records indicating access was denied on the first attempt in June 2024.

The building's maintenance history shows consistent attention to pest control, with regular inspections and bait applications being conducted, though the presence of rodent activity has been repeatedly documented through 2024 and into 2025. The property has maintained compliance with its bedbug reporting requirements since the 2022 violation, with all subsequent reports showing zero infested units. Two plumbing-related permits were issued for the building, one in 2018 and another in 2025, indicating ongoing infrastructure maintenance and improvements.
