Augrented Insights Report for 306 Union Avenue

306 Union Avenue is a 6-story, 21-unit New Law Tenement building located in Williamsburg, Brooklyn, and owned by Frank Lang. The 1920 building has experienced recurring issues with heating and hot water systems throughout 2024-2025, with numerous emergency complaints filed by tenants between December 2024 and February 2025, many of which involved entire-building outages.

The building's 311 service history also reveals pest-related challenges, including rodent sightings reported in June 2025 and previous inspections indicating rat activity as recently as July 2025. Apartment 3B was cited in late 2024 for multiple violations, including missing carbon monoxide detectors, absent smoke detectors, and a defective door, while inspections in 2023 identified issues with fire escape obstructions on multiple floors. The building's maintenance history shows a consistent pattern of heating system failures and pest infestations over the past few years, with Housing Preservation and Development (HPD) unable to gain access to affected units in several cases.

Monthly bedbug reports from 2021 through 2025 indicate zero verified infestations during this period. It's worth noting that the building currently has an active violation regarding the failure to file a 2021 External Low Pressure Inspection, issued in June 2023. The property's maintenance record suggests ongoing challenges with both heat/hot water systems and pest control, though some violations have been closed following inspections and repairs.
