Augrented Insights Report for 401 East 21st Street

401 East 21st Street, a 4-story, 20-unit New Law Tenement built in 1918 in Flatbush, has experienced significant maintenance and safety issues over recent years. Most notably, the building suffered fire damage in October 2024 affecting multiple units (A1, A2, B2, C2, C3, D2, D3) and resulted in active DOB violations.

The property has ongoing rodent issues, with multiple inspections in 2025 (April, May, June) showing rat activity, though bait was applied in June 2025. There are several open violations from October 2024, including problems with roof decking, a defective bulkhead door, and a second-story public hall window. The building has a history of various maintenance problems, as evidenced by multiple 2025 HPD complaints, including issues with paint/plaster on walls and ceilings, water leaks, heat/hot water complaints, and intercom problems.

A concerning pattern of infrastructure issues emerged in June 2025, with multiple emergency housing maintenance complaints regarding electric power outages, toilet problems, and other various maintenance issues. The building also experienced a brief period of structural concern in late 2024, with two building shaking/vibrating complaints filed in December 2021 and October 2024, though these were subsequently resolved. While the building's bedbug report history from 2019 to 2024 shows zero infestations, the recurring rodent issues and recent fire damage suggest ongoing challenges with building maintenance and resident safety.
