598 9th Avenue, Manhattan, NY 10036
The four-story, six-unit Old Law Tenement building at 598 9th Avenue in Hell's Kitchen, owned by Deborah Kasner, has experienced several concerning structural and safety issues in 2025. Most notably, in May 2025, serious facade problems were identified, including deteriorating concrete encased lintels and spalling brick throughout the building's perimeter, with particular concern at the second-floor window lintel above the entrance.
This was accompanied by two complaints in May 2025 regarding building shaking and structural stability concerns, and three complaints in June 2025 related to plumbing issues. While the building has maintained a consistent record of passing rodent inspections since 2010, there was a notable pattern of food safety-related incidents between 2019 and 2023, including multiple reports of food poisoning, odor issues, and problems with food worker hygiene and allergy information, though many of these complaints were determined to be isolated incidents and were administratively closed.
The building has demonstrated compliance with bedbug reporting requirements from 2019 through 2024, consistently reporting zero infested dwelling units. Two building violations pertaining to the facade were issued in May 2025, though one related to sidewalk protection was subsequently dismissed after verification of completion.
