5211 6th Avenue, Brooklyn, NY 11220

5211 6th Avenue is a 3-story, 6-unit New Law Tenement building in Sunset Park, constructed in 1931 and currently owned by Jennifer Lau. The building has experienced recurring heating and hot water system issues over the past several years, with eight documented complaints between 2019 and 2024, including three complaints in 2024-2025 alone. These complaints have generally been treated as emergencies by the Department of Housing Preservation and Development (HPD), though inspections have often been unable to gain access to units or found that systems had been restored prior to inspection.

More recently, in April 2023, significant boiler-related violations were recorded, including issues with the boiler flue, front jacket, and various safety concerns, resulting in penalties and requiring correction. Between 2020 and 2022, the building received several Housing Maintenance Code violations related to safety requirements, including the need for proper carbon monoxide and smoke detector notices, registration information, and a gas leak emergency procedure notice. The building has maintained a clean record regarding bedbug infestations, with zero reported cases in annual filings from 2019 through 2024, indicating effective pest management practices.

The current legal and maintenance history suggests persistent challenges with the building's heating systems, with complaints continuing into 2024-2025, despite previous violations being resolved. The April 2023 boiler violations represent the most significant recent maintenance concern, though these have been marked as resolved according to Department of Buildings records. The building's age and history of heating system complaints indicate that while some violations have been addressed, temperature control remains an ongoing issue, with multiple complaints about inadequate heat and hot water supply over the years. However, the consistent zero count for bedbug infestations over multiple years is a positive indication of effective pest control measures being implemented.
