Augrented Insights Report for 644 Classon Avenue

The three-story, two-unit building at 644 Classon Avenue in Crown Heights, owned by Ismene Speliotis, has a documented history dating back to its 1920 construction as an Old Law Tenement.

The property has shown consistent maintenance and compliance with NYC housing regulations in recent years, with no reported bedbug infestations in the past four years and successful rodent inspections passing every year since 2023. Recent maintenance activity includes a door-related complaint filed in December 2024, which was investigated by HPD and found not to violate housing laws, though this was classified as an emergency complaint.
