A regulated 6-unit Bushwick rental with 2 open hazardous violations and recent indoor air quality calls within three blocks.
This 6-unit Bushwick building operates as regulated affordable housing. While overall building-level filings are low, the address carries 2 open Class C hazardous violations and recent winter heat complaints. Three things to know:
Two Class C hazardous violations remain open for hot water and boiler access. Two violations from May 11, 2024, remain open at Class C, the immediately hazardous level. One calls for hot water restoration in Apt 2A, while the other flags a locked basement door preventing ready access to the boiler room.
A cluster of heat and hot water complaints was logged in early 2025. Tenants filed 3 heat and hot water complaints between January and April 2025, covering both individual apartments and building-wide outages. Although those calls were resolved, the lack of open boiler access in the violation record remains an operational concern for winter.
Indoor air quality complaints have surfaced within three blocks of the building. Within three blocks of the building, neighbors logged 3 indoor air quality calls in the past year, most recently on June 10, 2026. These airborne odor and vapor complaints typically signal HVAC or riser bleed across adjacent spaces.
