Augrented Insights Report for 550 East 21st Street

The 54-unit, 6-story building at 550 East 21st Street in Flatbush, owned by 550 East 21 LLC and constructed in 1952, has experienced several concerning issues in recent years. Most notably, recent inspections and service requests in 2025 have documented ongoing rodent problems, with multiple bait applications continuing as of July 2025. The building has also faced recurring heating and hot water challenges, particularly during late 2024 and early 2025, with multiple emergency complaints filed through HPD.

Plumbing issues, including radiator problems, were reported in early 2025. The elevator system has been a persistent concern, with multiple complaints about single device operation and no alternate service dating back to 2021. Recent environmental control board violations from 2024 highlight building maintenance issues, including concerns about cracked entrance columns and a problematic motor room.

The building has experienced pest infestations, with documented rodent issues in common areas and individual apartments (notably in apartments 1H and 5A). Infrastructure problems have included hallway humidity and elevator maintenance challenges, though some building-wide issues have been addressed through various repairs and violations being certified as corrected. The property has shown some responsiveness to maintenance requirements, as evidenced by the certification of certain violations, but ongoing rodent treatment and service requests suggest continuing challenges with building systems and pest management.
