731 6th Avenue, Brooklyn, NY 11215

731 6th Avenue is a 3-story, 6-unit old law tenement building located in Sunset Park, owned by Betty Wong and constructed in 1931. The building has experienced several maintenance issues in recent years, with the most recent concerns emerging in 2025 involving plumbing problems with a bathtub/shower (inspector unable to gain access) and radiator issues (reported as corrected). The property has faced recurring rodent-related challenges, with inspections revealing rat activity in May 2025 and previous sightings in 2024 and 2023, though earlier inspections in 2024 and 2023 passed without violations.

The building has multiple open violations related to bedbug reporting requirements from 2021-2024, and in 2019, there were several violations regarding required safety notices for smoke detectors, carbon monoxide detectors, gas leak procedures, and building registration information, which appear to remain unresolved. The building's maintenance history includes various inspections and repairs, with some systems requiring attention over the years. In 2019, inspections addressed flooring and electrical wiring issues, though no violations were found.

The Department of Buildings received a complaint in 2018 regarding construction work beyond approved plans, but this was unsubstantiated based on department records. While there was a bedbug reporting period from 2018-2019 showing no infestations or eradication efforts, the building has continued to face various compliance requirements. Most recently, a rodent compliance inspection in July 2025 found the building to be in compliance, though this follows earlier rat activity reports. The property's maintenance history shows a pattern of ongoing monitoring and inspection requests, with some issues requiring repeated attention from various city agencies.
