635 9th Avenue, Manhattan, NY 10036

635 9th Avenue is a 5-story, 8-unit Old Law Tenement building located in Hell's Kitchen and currently owned by Robert Malta. The 1920 building has experienced persistent heat and hot water issues, with eight documented complaints between 2022 and 2025, four of which were for the entire building and four for individual apartments. Most recently, in May 2025, HPD issued violations related to heat/hot water problems, and the department had previously been unable to gain access to inspect these recurring issues in multiple instances throughout 2024.

The building has multiple open violations requiring the annual filing of bedbug reports from 2021 through 2024, and several concerning safety equipment, including open violations from 2022 related to defective carbon monoxide and smoke detectors in apartment 2. The property has faced various regulatory challenges beyond routine maintenance issues. In 2024, there was an active violation regarding the failure to file 2023 external low-pressure inspection documentation, and significant violations related to an entrance storm enclosure that reduced sidewalk width, with associated penalties of $3,125.

The building's owner was also served an Oath violation in 2021 for illegal conversion. Notably, despite these issues, the building has maintained consistent compliance with rodent inspections, passing all 10 inspections conducted between December 2022 and July 2024. The property has experienced recurring issues with heat and hot water systems, marked by multiple emergency complaints, though some recent complaints have shown improved resolution, such as the August 2024 complaint where conditions were verified as corrected.
