Augrented Insights Report for 309 Henry Street

The four-story, three-unit residential building at 309 Henry Street in Brooklyn Heights, built in 1849, has experienced several notable occurrences over the past few years. The most significant recent issues have been related to safety and maintenance concerns, with three specific violations noted during 2022-2023: a fire escape obstruction by an air conditioning unit on the fourth floor (2023), and two instances of defective self-closing doors in public areas - one regarding a fire door on the first floor (2023) and another concerning the entrance door (2022).

The building has also faced recurring heating system issues, most recently documented in July 2021 when hot water problems were reported in Apartment 1, leading to HPD violations, though these were subsequently closed. Inspection records from 2021-2022 reveal multiple building code violations requiring attention to self-closing doors in various areas, including the boiler room in the cellar, and concerns about refuse accumulation in the cellar area. The property underwent several construction-related inspections in early 2022 that resulted in Environmental Control Board violations regarding unsafe conditions and excessive combustible debris, with associated fines totaling $3,780 that were marked as resolved.

More recently, rodent inspections in early 2023 indicated rat activity in February, with bait applied in March 2023. However, the building's bedbug reporting records from 2021 to 2024 show no infestations were reported during these periods, suggesting effective management of this particular issue. The most recent complaints regarding sidewalk conditions and support scaffolding in 2024 were inspected and found to have no violations warranting action.
