84 4th Avenue, Brooklyn, NY 11217

84 4th Avenue in Boerum Hill is a 5-story, 10-unit residential building constructed in 1920 and currently owned by 59 St Marks LLC. The property has experienced several recurring maintenance issues in recent years, with the most recent complaints in 2025 involving unsanitary conditions related to mold (investigated but not found to violate housing laws) and a previous water leak in 2024 that was similarly inspected without resulting violations. There was a notable incident in November 2023 involving a heat/hot water complaint, though inspections could not be conducted due to lack of access.

The building has also had multiple standing water issues documented in 2022, including both sidewalk puddles and sewer drain concerns that were inspected with no violations found. The property has maintained a clean record with respect to bedbugs, filing multiple reports from 2020 through 2025 showing zero infested units or eradication requirements, and no infestations were reported in the most recent 2025 filing period. Additional historical records show some infrastructure concerns, including a 2022 complaint about drainage issues that was referred to the Department of Environmental Protection, and a 2023 inquiry about defective/exposed electrical wiring that resulted in no violations.

The building has undergone some permitted work in 2020, with two separate permits issued for electrical and alteration work. Historical records from 2012 indicate rodent baiting activities were conducted. While the property has experienced various maintenance issues, it's worth noting that most recent complaints have not resulted in violations, though there appears to be an ongoing pattern of moisture-related concerns, particularly regarding mold and water issues.
