Augrented Insights Report for 638 Classon Avenue

This 4-story, 6-unit tenement building at 638 Classon Avenue in Crown Heights, owned by Abraham Herman and dating back to 1930, has experienced recurring maintenance issues over the past two years. Most notably, between late 2023 and November 2024, there have been multiple complaints regarding heat and hot water problems, particularly in February 2024 and November 2024, with both emergencies requiring HPD intervention.

The building has also faced persistent plumbing issues, including radiator and sink problems, with several complaints filed in 2024 alone. Safety concerns have been documented, with issues regarding the fire escape and unsanitary conditions related to garbage/recycling storage noted in July 2023, though HPD was often unable to gain access for inspection. The property has a pattern of maintenance violations, as evidenced by citations issued in May 2024 for encumbrances in public halls across multiple stories and a failure to post required registration signage.

While the building's bedbug reporting from 2021 to 2024 shows no recorded infestations, there are significant rodent control issues, with multiple inspections between 2023 and 2025 consistently detecting rat activity, though a "Passed" inspection in May 2024 offers some relief. A gas utility referral in August 2024 resulted in no violations being found during inspection. The building's maintenance record shows a troubling pattern of unaddressed complaints, particularly regarding access for inspections, with multiple cases in 2024 where HPD could not gain entry to investigate reported problems.
