510 East 12th Street, Manhattan, NY 10009

510 East 12th Street is a 5-story, 20-unit Old Law Tenement building located in the East Village and constructed in 1920, currently owned by Zachary Kadden. The property has experienced several significant maintenance issues in recent years, most notably with multiple open complaints since February 2025 regarding flooring, ceiling, and wall conditions. There was a concerning heat and hot water issue reported in March 2024 that was closed without confirmation of access for inspection.

The building has a history of safety violations, including three active Environmental Control Board violations from 2024 relating to structural work done without a permit, and failure to comply with previously issued violations, each carrying a penalty of $6,250.00. Previous violations from 2021-2022 included multiple safety concerns such as defective emergency lights, exposed electrical wiring, and issues with gas piping. In late 2021, significant violations were documented in Apartment 1, including problems with heat, smoke detectors, carbon monoxide detectors, and various structural and maintenance issues that were ultimately resolved.

The building has undergone regular rodent inspections, with the most recent showing compliance in July 2025, though there were instances of rat activity noted in January 2025 and earlier in 2023. Bedbug inspections have consistently shown no infestation from 2021 through 2025. Recent building maintenance requests indicate ongoing issues with basic maintenance, as evidenced by the four open complaints regarding paint/plaster conditions and flooring problems filed in February 2025. While some violations from earlier periods have been resolved or dismissed, there remains a pattern of recurring maintenance issues that require ongoing attention, particularly regarding building systems and interior maintenance.
