Augrented Insights Report for 421 Classon Avenue

The three-story, 6-unit building at 421 Classon Avenue in Bedford-Stuyvesant, owned by Samuel Schwartz and constructed in 1930, has experienced a number of concerning issues in recent years, particularly related to safety and maintenance.

Most notably, the building has an open Housing Maintenance Code violation from April 2024 regarding the failure to file an annual bedbug report, and from July 2023 regarding the requirement to post carbon monoxide detector information. A significant inspection in July 2023 revealed multiple violations, including obstructions in hallways and fire escapes, missing safety notifications, and various encumbrances such as bicycles and household items in public areas.

The building has also faced persistent rodent issues, with multiple inspections between 2023 and 2025 consistently identifying rat activity, though a compliance examination in April 2025 showed improved conditions. While some 311 service requests have been addressed, such as a door-related complaint from 2023 that was inspected without resulting violations, the building's record shows ongoing challenges with maintenance compliance and pest control, despite some recent improvements in rodent management.
