320 South 4th Street, Brooklyn, NY 11211

320 South 4th Street is a 4-unit, 4-story residential tenement building located in Williamsburg, constructed in 1910 and currently owned by Antonio Santana. The building has undergone several inspections and reported incidents over the past five years, with the most significant pattern being related to bedbug reporting compliance.

Between 2021 and 2024, the property received four consecutive Class A violations for failure to file annual bedbug reports as required under the Housing Maintenance Code, though recent filings from 2024 indicate no infested units and successful eradication efforts during the most recent reporting period (2024-2025). The building has faced some serious concerns regarding unauthorized modifications, with the Department of Buildings issuing a violation in October 2022 related to illegal conversion of the cellar space. This violation, which was documented as work completed without proper permits including installation of partitions, doors, and plumbing features, resulted in a closed status with an Oath Violation Served disposition.

Prior to this, the building underwent two successful rodent inspections in December 2018, passing both evaluations. The most recent bedbug report (2024) shows proper compliance with HPD requirements, though there were compliance lapses noted in earlier years. The property appears to have resolved its bedbug reporting issues, with no reported infestations or extermination required in the most recent filings.
