Augrented Insights Report for 1821 Mahan Avenue

1821 Mahan Avenue is a 20-unit, 3-story residential building constructed in 1963, currently owned by Christina Balsamo. The building has experienced recurring issues with heat and hot water systems, with multiple emergency complaints filed in 2023-2025 regarding complete building failures, though HPD often could not gain access for inspection.

Recent maintenance concerns include open complaints from 2025 about door issues and plumbing problems, both categorized as emergencies. The building has undergone several inspections revealing various violations, including an open violation from 2023 regarding inadequate hot water supply in apartment 2A, and multiple heating system complaints suggesting persistent temperature control issues. Other notable events include water-related problems in late 2023, with both heavy flow and slow leak incidents reported, though some were resolved with no violations issued.

The building has experienced some internal maintenance issues, including a recent violation in 2024 concerning broken plaster surfaces and paint in apartment 2C, as well as door-related violations. Safety compliance appears to be an ongoing challenge, with several open violations from 2023 regarding posting requirements for carbon monoxide detection and heating system access. While the building has maintained regular bedbug reporting requirements (most recently showing no infestations for the 2023-2024 period), rodent inspections in 2022 showed mixed results, with some failures noted for "Other Reasons." The property has active Department of Buildings violations from 2023 concerning the failure to file external low-pressure inspections for 2019 and 2021, and historical records show a scaffolding violation from 2018.
