321 East 54th Street, Brooklyn, NY 11203

The 2-story, 4-unit building at 321 East 54th Street, owned by Steven Mercier and constructed in 1920 as a "New Law" tenement, has experienced consistent regulatory oversight in recent years, particularly regarding bedbug reporting compliance. As of April 2024 and March 2023, the building has open violations related to the failure to file mandatory annual bedbug reports, continuing a pattern observed since 2021 when this requirement was initially violated.

The building underwent a series of safety and compliance inspections in 2018 that revealed multiple issues, including the need to properly post safety notices regarding carbon monoxide detection, gas leak procedures, and housing information guides in common areas. During the same period, violations were recorded concerning a self-closing door requirement for the basement boiler room and the improper use of a basement area that had been converted into a living space with plumbing fixtures. These issues were subsequently addressed and certified as closed by March 2022.

Of particular note was a significant complaint and violation in 2018 regarding illegal conversion of cellar space, though this was ultimately dismissed upon inspection in October 2018, showing no violation warranted at that time. While the building's bedbug infestation rates appear to have been managed from 2020-2021, with no reported affected units during that period, the ongoing open violations related to bedbug reporting requirements suggest a continuing compliance challenge in maintaining required documentation. The property has undergone regular inspection cycles, with most historical violations being addressed and closed, though the current bedbug reporting violations represent the most recent compliance issue as of mid-2025.
