Augrented Insights Report for 823 Classon Avenue

823 Classon Avenue is a 6-story, 24-unit residential building constructed in 1925 in Crown Heights, currently owned by Kosha Diaz. The property has experienced several notable maintenance and safety issues over the past few years, with the most recent being a DOHMH heat complaint filed in December 2024 regarding inadequate heat, which was officially closed in February 2025. Between 2019-2020, the building underwent construction work that led to multiple violations, including failure to provide required tenant protection documents and construction notices, though all these ECB violations were subsequently resolved.

The building has maintained a good record regarding bedbug infestations, with all bedbug reports from 2021 to the present showing zero infested units. Recent inspections have consistently passed rodent inspections, with the most recent inspection in July 2025 continuing this trend of compliance. The Department of Buildings has recorded several construction-related complaints, particularly in 2021, including issues with scaffolding and sidewalk shed safety, though inspectors generally found no violations warranting penalties.

Active violations remain on record from 2019 for failure to perform a Category 5 inspection and benchmark energy use reporting, which appear to be unresolved as of the latest available data. The building's history shows a pattern of addressing violations promptly when they occur, with most being resolved through proper certification or compliance measures. Regular rodent inspections and consistent bedbug reporting suggest ongoing attention to public health concerns, though the building has experienced periodic heat-related complaints that may indicate maintenance challenges.
