645 40th Street, Brooklyn, NY 11232

The three-unit, three-story residential building at 645 40th Street in Sunset Park, owned by Xiu Fei Liu, has experienced several notable maintenance and safety events since 2019. Most recently, in 2024, the building had a gas utility referral complaint, though inspectors were unable to gain access during their second attempt.

The property has undergone four consecutive annual inspections (2021-2024) regarding bedbug reporting requirements, for which violations were issued until the issues were properly addressed. Earlier violations in 2019 included safety concerns such as a gas leak notice requirement, multiple instances of encumbrances (baby strollers and a bicycle) blocking first-story public hallway access, and several significant maintenance issues in the third-floor apartment.

These third-floor violations included a locked door obstructing emergency egress, defective window guards requiring repair or replacement, and concerns about presumed lead-based paint hazards in the kitchen ceiling that needed correction using appropriate work practices. While the building has had various violations over the years, it's worth noting that all these issues have been officially marked as "Close," indicating they were resolved, though the bedbug reporting violations persisted for multiple years before being addressed.
