312 73rd Street, Brooklyn, NY 11209

This 5-unit, 3-story residential building at 312 73rd Street in Bay Ridge, owned by Linda Lu and constructed in 1915, has experienced several recurring maintenance issues over recent years. Most notably, there were multiple indoor air quality complaints in March 2024 involving chemical vapors, which followed a pattern of similar air quality concerns in 2024 and 2023.

The building has a documented history of heating and hot water system problems, with emergency complaints recorded in January and December 2022. During this period, there were also significant pest control issues, with violations issued in January 2022, and subsequent infestations affecting multiple units, particularly in apartments 3F and 3R, as documented in 2022. The building underwent various safety and maintenance improvements in 2022, including the removal of unauthorized locks and the installation of necessary window guards, though some violations related to door repairs and pest control persisted.

In 2022, several violations were addressed regarding fire safety requirements, including posting notices for gas leak procedures, smoke detector, and carbon monoxide detector requirements, though some compliance dates were extended. More recently, there have been two consecutive complaints in 2024 and 2025 regarding unpermitted work in the occupied multiple dwelling, but inspectors were unable to gain access for verification. The building has maintained a consistent record of bedbug management, with official reports showing no infested units and successful eradication of affected units across multiple reporting periods from 2020 through 2025.
