537 Lenox Avenue, Manhattan, NY 10037
The five-story, eight-unit Old Law Tenement building at 537 Lenox Avenue in Harlem, built in 1910 and currently owned by Icer Of 537 Lenox Ave LLC, has experienced ongoing heating system challenges in recent years. Between 2024 and 2025, there were multiple complaints and emergencies reported regarding inadequate heat and hot water, affecting both individual apartments and the entire building. The building's heating system has generated particular concern, with several complaints filed through 311 and HPD showing similar issues recurring every few months, including three complaints in November 2024 alone.
Additionally, the building faced some safety concerns in 2024, including a C-class violation regarding defective self-closing doors at the entrance and heating system access issues. The property has undergone several inspections and received multiple violations related to safety systems between 2021-2022, including problems with carbon monoxide detectors, smoke detectors, and window guards in Apartment 4. A significant environmental control board violation was recorded in 2019 regarding deteriorating building facade elements, though this was resolved with a $1,250 penalty.
More recently, in 2025, the building has been under rat management treatment, with multiple inspections showing rat activity and bait applications between January and July 2025. Despite these challenges, the building has maintained a clean record in terms of bedbug infestations since at least 2020, with no reported cases in the past five filing periods. The landlord's access issues have been a recurring theme in inspection records, with multiple instances of inspectors being unable to gain access during investigations, particularly notable in complaints regarding the boiler system and various housing maintenance code matters.
