543 84th Street, Brooklyn, NY 11209

The two-family house at 543 84th Street in Bay Ridge, owned by Quocdan Ly, has experienced significant heating system issues, particularly during late 2020. The building, constructed in 1925, faced multiple heat and hot water complaints between November 25, 2020, and December 29, 2020, with at least ten separate incidents reported through 311 calls and Housing Maintenance Code complaints during this period.

Many of these complaints were duplicates, indicating a building-wide heating problem affecting multiple units. The Department of Housing Preservation and Development (HPD) was frequently unable to gain access to units for inspection, though some inspections were conducted, and violations were eventually issued.

The situation culminated in a Class C violation issued on December 30, 2020, specifically for inadequate heat supply in Apartment 2 on the second story, with a certification date of January 11, 2021. While all these complaints and violations were eventually closed, the concentration of heating system issues during this three-month period in late 2020 suggests a significant system failure at that time. Since January 2021, there have been no reported heat or hot water complaints in the building, which may indicate that the heating system issues were resolved, though this cannot be definitively confirmed without more recent data beyond 2023.
