140 4th Avenue, Brooklyn, NY 11217

140 4th Avenue is a 5-story, 10-unit residential building constructed in 1931 in the Gowanus neighborhood, currently owned by Zev Baum 1 LLC. The building has experienced several recurring maintenance issues over the past few years, with the most recent concerns involving plumbing issues in June 2025 and a heavy water leak in March 2024, both of which HPD was unable to inspect properly despite tenant reporting.

In 2023, there were ventilation-related indoor air quality concerns reported to DOHMH, and as of late 2022, there was an ongoing investigation into construction lead dust affecting both common areas and individual apartments. 2022 also saw multiple housing code violations and service requests, including problems with heat and hot water for the entire building, window frame issues, and serious construction-related concerns including potential lead paint problems. The building has a documented history of rodent issues between 2012 and 2016, with multiple inspections showing rat activity and the need for baiting, though it appears to have passed more recent rodent inspections.

All four previous bedbug reports between 2019 and 2025 show zero infestation cases, suggesting successful pest management. The property has undergone various maintenance inspections and repairs, with notable violations related to apartment 4R including issues with light fixtures, bathroom and kitchen wall maintenance, and window guard compliance, all of which have since been marked as closed. Additional building safety improvements were mandated in 2021, including requirements for carbon monoxide detector notices and smoke detector requirements, and a 2021 wall complaint regarding bulging/cracked conditions was closed due to access issues.
