Augrented Insights Report for 387 Prospect Avenue

387 Prospect Avenue is a 6-unit, 3-story brick building located in South Slope, Brooklyn, constructed in 1920 and currently owned by Andreas Steiner. The property has experienced recurring heating system issues, with multiple emergency heat/hot water complaints registered between 2021 and 2025, including January 2025 and September 2023, though in each case tenants reported restoration of service during HPD inspections.

The building has also faced rodent issues, with rat sightings reported in July 2024 and June 2025, and an initial rodent inspection in June 2025 confirming rat activity, though a subsequent inspection in August 2024 showed compliance. Additional historical concerns include a sewer plumbing issue and mold problem reported in September 2021, with violations issued for unaddressed water and unsanitary conditions in the basement that November.

A complaint regarding work without a permit in May 2024 was inspected and found to warrant no violation. Notably, the building has demonstrated consistent bedbug prevention management, with no reported infestations in official filings from 2019 through 2024. The property has one documented Housing Maintenance Code violation from October 2023 regarding an improperly posted heating system contact notice, and three violations from September 2021 related to basement conditions, all of which have been certified as closed.
