1123 1st Avenue, Manhattan, NY 10065
1123 1st Avenue is a 5-story, 16-unit Old Law Tenement building located in Manhattan's Upper East Side, constructed in 1910 and currently owned by Lior Dishi. The building has experienced recurring heat and hot water issues, particularly documented between 2019-2024, with multiple complaints regarding both whole-building and apartment-specific outages. More recently, in July 2024, there were problems with cooking gas in apartment 4A, which led to violations being issued.
The building has also faced pest control challenges, with significant rodent and insect/garbage issues reported in multiple years (2022-2023), though rodent inspections from 2016-2019 consistently passed. In terms of building maintenance and safety compliance, there are several notable violations and ongoing issues. A September 2024 inspection found defective vestibule door hinges, resulting in an open Class C violation.
The building has missed multiple low-pressure inspection filings (2018 and 2021) under DOB regulations, with an active violation issued in June 2023. Of particular historical interest, in 2018, the building was cited for several violations related to unauthorized transient use, including lack of proper sprinkler and fire alarm systems, though these were subsequently resolved. The building's bedbug reporting history shows only one infested unit in the 2022-2023 period, with no reported infestations in the most recent filings. While the building has experienced various maintenance issues over the years, including window repairs and safety notice postings, many violations have been addressed promptly, with multiple inspections showing compliance in recent years, particularly in terms of building-wide rodent control.
