5203 6th Avenue, Brooklyn, NY 11220

At 5203 6th Avenue in Sunset Park, a 6-unit New Law tenement building constructed in 1931 and currently owned by Jennifer Lau, there have been recurring issues with building systems and safety features over recent years. The most recent significant event occurred in February 2025, when there was an outage of heat and hot water affecting the entire building, though these services were confirmed restored during the HPD inspection. This was the seventh documented heat/hot water complaint since 2020, with similar issues reported in 2024, 2023, 2021, and 2020.

The building has also experienced various safety concerns, including a carbon monoxide detector issue and smoke detector problem in July 2022, both of which resulted in emergency HPD responses but no violations were issued. Other maintenance issues have included a water leak, door and window problems, and wall repair needs, particularly in 2021 when multiple complaints were filed simultaneously. The building's maintenance history reveals several open violations, including one from 2023 concerning a mouse infestation in apartment 3B and ongoing issues from 2020 regarding paint conditions in both the boiler room and apartment 3B.

While the property has had multiple emergency service requests and inspections, most have not resulted in violations being issued. The building's boiler system appears to have required attention, with three separate complaints about defective or inoperative boilers recorded between 2019 and 2021, though each inspection determined no violations were warranted. Importantly, the building has maintained a clean record with respect to bedbug infestations since 2017, and recent rodent inspection records show passing results in 2018, though there were some failures in compliance noted in previous years. The property has seen consistent 311 service usage over the years, with the majority of complaints being promptly closed, though many have required multiple follow-up requests to address recurring issues.
