Augrented Insights Report for 270 Clarkson Avenue

270 Clarkson Avenue is a 6-story, 99-unit residential building constructed in 1962, currently owned by Barry Hers. The property has experienced several ongoing maintenance issues in recent months, particularly between May and July 2025, with numerous complaints regarding heat and hot water outages, plumbing problems, and unsanitary conditions including mold. Notable incidents include three separate complaints about heat/hot water issues during May 2025, water supply problems in early May 2025, and repeated issues with plumbing fixtures including bathtub/shower problems.

The building has active violations related to failure to maintain building systems, including open violations from late 2024 affecting apartment 112, covering multiple maintenance issues such as plumbing fixtures, water supply, and interior surfaces. The building's history reveals recurring infrastructure challenges, including a pattern of heating system failures and plumbing problems. Recent rodent control efforts are ongoing, with multiple baiting operations conducted throughout 2024-2025, though inspections in 2024 and 2025 showed rat activity.

The property has also faced regulatory scrutiny, with several Department of Buildings complaints and violations, including an active illegal conversion complaint from late 2024. Previous violations documented in 2018-2020 involved various systems including the elevator, boiler, and plumbing work, often citing access issues for inspections. While recent bedbug reports indicate no current infestations, the building has experienced multiple episodes between 2019-2023, with the most recent cases showing zero infestation between 2023-2024. The building's management has faced challenges in maintaining compliance with inspection requirements and addressing housing maintenance code violations in a timely manner, as evidenced by multiple instances of inspection access denial and violations related to unpermitted work.
