529 49th Street, Brooklyn, NY 11220

529 49th Street is a three-story, six-unit New Law tenement building constructed in 1905 in Sunset Park, currently owned by Cuznhuang Yang. The building has experienced several maintenance and safety issues over the past years, with particular concern during the 2021-2022 period when multiple heating system problems were reported, including three separate heat/hot water complaints in December 2021 (two in one day, with emergency responses confirming restoration of services), and steam pipe/riser plumbing issues.

The building has also faced rodent-related challenges, with inspections in late 2022 failing for "Other Reasons" and a DOHMH complaint about rodent-attracting conditions in August 2022 that resulted in violations requiring follow-up inspections. Significant ongoing concerns include multiple open violations from December 2021 in apartment 2L, regarding safety equipment and systems including missing smoke and carbon monoxide detectors, and defective radiator air valves.

The building has documented issues with construction lead dust in December 2021, though inspections show this complaint remained "In Progress" as of October 2023. There were also two violations issued in 2023 related to failure to file external low-pressure inspections, with one still showing as active. Despite these challenges, recent bedbug reports (2022-2025) show zero infestation cases, and the property has maintained ongoing compliance reporting since 2022, though there was a regulatory violation for not filing the 2021 external low-pressure inspection that was subsequently dismissed.
