AI summary · updated June 2026

439 West 46th Street is a 5-story, 21-unit residential tenement building located in Hell's Kitchen, built in 1910 and currently owned by Adam Reisman. The property has experienced recurring heating and hot water system issues, with multiple building-wide complaints filed between 2023 and 2025, including two emergency complaints in March 2025 that were not able to be verified due to access issues. The building has also faced sanitation challenges, particularly regarding garbage and recycling storage in September 2023, for which violations were issued under the Administrative Code. Other notable issues include a plumbing problem related to water supply in June 2023, exposed electrical wiring in the first-story vestibule in May 2023, and several self-closing door violations affecting the basement access between 2022 and 2023.

The building underwent three Tenant Safety Inspections in September 2024, all resulting in 'Compliance Inspection Performed' findings. While there have been several rodent inspections between 2018 and 2024, with some indicating rat activity in 2024, most inspections passed. The property shows consistent attention to maintenance with multiple Electrical Wiring (EW) permits issued between February and December 2020, though access issues have sometimes hindered verification of repairs. Importantly, the building has maintained a bedbug-free record over the past six reporting periods from 2019 to 2024, with zero reported incidents of infestation, eradication, or re-infestation during this time.
