315 South 4th Street, Brooklyn, NY 11211

The 4-story, 8-unit tenement building at 315 South 4th Street in Williamsburg, owned by Virgilio Then and constructed in 1920, has experienced several significant maintenance and health-related issues over recent years. Most notably, in June 2025, the Department of Health and Mental Hygiene conducted an inspection that revealed rodent activity, adding to previous concerns about pest problems in the building.

The property has consistently demonstrated good bedbug management practices, with annual reports from 2019 through 2024 showing zero infested units, though a recent inspection in March 2022 did note a violation regarding the filing of annual bedbug reports. The building has faced various regulatory challenges, including an active violation as of September 2024 for failure to file the 2023 external low-pressure inspection, and previous Housing Maintenance Code violations related to unauthorized basement partitions in February 2021 and bedbug reporting requirements in March 2022.

Multiple complaints regarding illegal conversions were filed in 2021, though inspections either found no violations or resulted in the inspector being unable to gain access. The property's rodent situation appears to be an ongoing concern, with failed inspections in December 2018, though a compliance inspection in January 2019 did pass. The combination of pest issues, building code violations, and regulatory non-compliance suggests ongoing maintenance challenges, though the consistent zero infestation status in bedbug reporting indicates effective management of that particular issue.
