Augrented Insights Report for 520 East 21st Street

The 6-story, 102-unit building at 520 East 21st Street in Flatbush, owned by Yechiel Weinberger and constructed in 1951, has experienced numerous infrastructure and maintenance issues in recent years. Most concerning is the building's persistent rodent problem, with multiple inspections in 2025 (including one in July 2025) confirming rat activity despite baiting efforts since late 2024.

The property has also faced significant elevator-related challenges, with multiple complaints and violations between 2023-2025 regarding car functionality, including misalignment, leveling issues, and missing buttons, some of which resulted in ECB violations. Recent building conditions have generated considerable tenant concerns, including unsanitary garbage storage, water leaks, and sewage odors in 2025, with the Department of Health issuing violations related to these issues. The building's maintenance history reveals substantial interior problems, particularly in Apartment 2H, which was cited in December 2024 for multiple violations including mold, water damage, and deteriorating plaster surfaces.

Exterior maintenance issues are documented, with active ECB violations from 2023-2024 noting problems with the building facade, including cracked bricks and other structural concerns, along with several outstanding Administrative Code violations regarding energy efficiency reporting. The property has maintained a clean record regarding bedbug infestations since 2019, with zero reported cases in recent years. Current active violations include unresolved issues with elevator certification and appearance requirements, as well as persistent rodent activity despite repeated remediation attempts.
