140 St Marks Avenue, Brooklyn, NY 11217

140 St. Marks Avenue is a three-story, four-unit residential building in Prospect Heights, constructed in 1871 and currently owned by 140 St. Marks LLC.

The property has experienced several significant maintenance issues in recent years, most notably a pair of emergency heat and hot water complaints in April 2025, which were promptly closed the following day. The building has a concerning pattern of non-compliance with regulatory requirements, including two active violations (as of 2023) for failing to file annual boiler and external low-pressure inspection reports. There was also a recent illegal conversion complaint filed in May 2025, though access was denied on the first inspection attempt in July 2025.

The building has maintained a relatively consistent record regarding bedbug reporting, with no reported infestations in the 2022-2023 filing period, though it has received multiple violations (2019-2024) for failing to file annual bedbug reports as required under Housing Maintenance Code § HMC. Additionally, the property faced significant rodent issues in early 2019, requiring multiple bait applications between January and March 2019, though subsequent inspections showed improvement, with the last reported inspection in December 2019 passing. While the building's most recent bedbug report (as of April 2024) indicates no current infestations or eradicated units, the pattern of violations and repeated heating system complaints suggests ongoing maintenance challenges.
