6810 4th Avenue, Brooklyn, NY 11220

The three-story, four-unit building at 6810 4th Avenue in Bay Ridge, owned by Guoxin Qian, has a notable history of food establishment-related complaints between 2018 and 2024, primarily involving the Department of Health and Mental Hygiene (DOHMH). While many of these complaints were ultimately administratively closed with the issues addressed, they included concerns about food preparation areas, food contamination, and a food poisoning incident in 2019 involving one or two cases.

The building underwent a comprehensive inspection in July 2018 that revealed multiple Housing Maintenance Code violations, primarily related to safety and compliance notices, including requirements for smoke detector and carbon monoxide detector information, gas leak procedures, and building registration notifications. These violations, along with others regarding encumbrances in public halls on the second and third stories, were certified as corrected between August and October 2018.

More recent activity includes two inspections conducted in 2024 - one for work without permits and another regarding the certificate of occupancy - neither of which resulted in documented violations. The building's bedbug inspection reports from 2020 through 2024 show no current infestations as of the most recent filing in December 2024, with only four units affected and eradicated in 2019 and 2020, suggesting successful pest management. While the food establishment complaints and initial safety violations in 2018 indicate past concerns about building conditions and safety compliance, more recent records from 2022 to 2025 show no recurring issues, though the building's conversion from Class B to Class A designation is noteworthy, indicating a change in building classification status.
