100 East 123rd Street, Manhattan, NY 10035

100 East 123rd Street is a 4-story, 10-unit residential building constructed in 1920 in East Harlem, currently owned by Keyoumars Keypour. The building has experienced recurring maintenance issues, particularly with water and heat systems, evidenced by multiple emergency heat/hot water complaints in late 2024 and early 2025, as well as recent water leak and mold issues reported in January 2025. The property has active violations related to failure to file 2018-2020 external low pressure inspections, though building management has maintained an effective pest control regime, with no recorded bedbug infestations between 2020-2025.

Significant past violations include inadequate heat and water issues reported in February 2024 and various unsanitary conditions in Apartment 1R, including mold and plaster problems which were documented and certified for repair in early 2024. Recent rodent control efforts have been notable, with multiple bait applications occurring throughout 2025, though initial inspections in February and March 2025 indicated rat activity. The building has a pattern of HPD inspections being unable to gain access to apartments for verification of reported issues, as seen in multiple complaints throughout 2024-2025.

Previous violations from 2024 are documented in the Housing Maintenance Code violations, including issues with a self-closing vestibule door in the basement and various maintenance problems affecting habitable spaces. The Department of Buildings records show historical complaints about plumbing systems, including a 2018 issue regarding an illegal curb cut. While the building has maintained a bedbug-free record since inspections began, the frequency of recent maintenance issues suggests ongoing challenges with building systems and access for necessary inspections.
