340 East 18th Street, Manhattan, NY 10003

340 East 18th Street is a 6-story, 24-unit residential tenement building located in Gramercy, built in 1910 and currently owned by Steven Croman. The building has experienced recurring heating and hot water system issues throughout 2025, with nine separate complaints filed between March and May 2025, all requiring emergency responses from the Department of Housing Preservation and Development (HPD). These complaints generally reported lack of heat and hot water throughout the entire building, with several instances where HPD was unable to gain access to inspect the reported conditions.

The building's boiler system has been a persistent concern, with multiple Department of Buildings complaints between 2023-2025 citing defective or inoperative equipment. Specifically, there are active Environmental Control Board violations as of 2024-2025 regarding an unregistered HB Smith dual fuel boiler with associated penalties totaling $4,800. In addition to the heating system problems, the building has had various maintenance issues affecting resident safety. The fourth-floor apartment 4A was cited in October 2024 for defective smoke and carbon monoxide detectors and inadequate hot water supply, while the fifth-floor apartment 5D received violations for missing safety equipment and defective self-closing doors.

A bedbug violation was noted in 2024 for apartment 3C. The building's rodent inspections have shown some concerning results, with "Rat Activity" recorded in April 2025 and September 2022, although earlier inspections from 2016-2021 had passed. The property has maintained a consistent record of bedbug-free status across multiple reporting periods from 2019-2025. To date, the building has experienced recurring heating system failures, with these problems appearing most consistently throughout 2025, suggesting ongoing infrastructure challenges particularly related to the building's boiler and heating systems.
