3401 Avenue J, Brooklyn, NY 11210
3401 Avenue J is a 6-story, 59-unit residential building located in the Flatlands neighborhood, built in 1930 and currently owned by Ramjag Mohanlal. The building has experienced recurring maintenance issues, particularly with heating systems, as evidenced by multiple complaints in 2021-2022 regarding heat and hot water outages affecting both individual apartments and the entire building.
More recent concerns include plumbing issues (2025), unsanitary conditions including pests (2025), mold (2025), and smoke detector violations (2025), with the Department of Housing Preservation and Development (HPD) issuing violations that require correction by the property owner. The building has also faced elevator safety concerns, with violations related to door lock monitoring and various mechanical issues documented between 2018-2021, though some of these complaints were found to lack merit upon inspection. Inspection records from 2023 show multiple Housing Maintenance Code violations related to lead-based paint hazard control requirements in various apartments (1F, 4A, 4D, 6C, 6F, 7C, 9C, 9F), while earlier records indicate some challenges with pest control and rodent inspections.
The building has maintained a consistent record of zero bedbug infestations reported in recent annual filings (2021-2025), though there was a specific bedbug reporting violation issued in 2024. Current open violations as of 2025 include failure to file required external low-pressure inspections between 2018-2023, and an active ECB violation from 2021 related to elevator door lock monitoring with an associated penalty of $1,280. While the building has demonstrated some improvement in recent years, with most complaints being addressed and closed, the pattern of recurring maintenance issues, particularly with building systems and safety equipment, is notable.
