146 East 123rd Street, Manhattan, NY 10035

146 East 123rd Street is a 5-story, 12-unit Old Law Tenement building constructed in 1910 and currently owned by Noel Intner. The property has experienced recurring maintenance issues in recent years, with the most recent cluster of complaints in June 2025 including flooring problems, potential mold issues, and water leaks, some of which resulted in violations. Previous significant maintenance concerns include a heat/hot water problem in November 2024, multiple plumbing issues (including sink and toilet problems), and a rodent infestation problem evidenced by multiple rat activity reports between 2024-2025.

The building has active violations related to unfiled external low-pressure inspections from 2019-2020, and previous violations from 2024 regarding hot water temperature, door issues, and pest control which were eventually certified as corrected. The property has undergone several inspections and maintenance activities, including multiple rodent baiting and compliance checks in 2025, though inspections frequently noted ongoing rat activity. The building's management has received multiple violations related to building maintenance standards, including issues with self-closing doors and heating systems, particularly affecting Apartment 1B.

While there have been numerous complaints and violations, the management has generally responded by addressing most issues, as evidenced by the "Closed" status on many complaints, though some recent problems remain unresolved. The historical record shows no bedbug infestations reported between 2019-2025, though there were three rat sighting complaints in late 2024 and 2025. The building's history also includes a set of violations from 2020 regarding unauthorized signage and an overhead canopy in disrepair, which resulted in fines totaling $7,250, though these were related to a business operation rather than residential conditions.
