433 West 43rd Street, Manhattan, NY 10036

The five-story, 34-unit building at 433 West 43rd Street in Hell's Kitchen, owned by Kalabi Realty Co. LLC, has a complex history since its construction in 1900. The property has undergone several significant events related to unauthorized conversions and maintenance issues, with the most recent major active violation being the failure to file FISP Cycle 9C Technical Report by February 2024.

Between 2018 and 2023, the building faced multiple Environmental Control Board (ECB) violations for various unauthorized works, including an improperly installed living room partition in Apartment 5A (2023), unauthorized bathroom renovations in Apartment 4A (2019), and illegal conversions related to transient use concerns. These violations typically resulted in fines, though most were eventually resolved. The building has maintained regular compliance with bedbug reporting requirements, with no reported infestations across the six most recent filing periods from 2019 to 2024.

Rodent inspections have generally shown positive results, with only one instance of rat activity in 2016 among ten consecutive inspections from 2010 to 2024. The property also experienced issues with elevator service in 2020 and has been subject to illegal hotel room complaints, particularly notable in 2019, when inspectors required follow-up visits to gain access. While many past violations have been resolved, there remains an active obligation to address the 2024 FISP reporting requirement. The building's management has demonstrated some responsiveness to regulatory requirements, as evidenced by the submitted bedbug reports and regular rodent inspections, though there have been notable lapses in permit compliance and maintenance certification in recent years.
