400 South 4th Street, Brooklyn, NY 11211

400 South 4th Street in Williamsburg is a 4-story, 6-unit Old Law Tenement building constructed in 1910, currently owned by Victor John. The building's most significant recent issues have revolved around garbage and recycling storage problems, with multiple complaints filed between 2020 and 2022, though these were generally classified as non-emergency situations. The property has experienced two notable heat and hot water incidents: a December 2020 emergency situation that was resolved, and a November 2019 complaint that could not be inspected.

Two bedbug-related violations were issued in 2021 and 2022 regarding annual reporting, though subsequent filings from 2022 through mid-2025 show no reported infestations. The building's maintenance history includes two dismissed violations in mid-2023 related to external low pressure inspections from 2018 and 2020. The Department of Buildings conducted a complaint inspection in November 2022 regarding egress issues, but found no violations at the time.

An April 2021 Housing Maintenance Code violation remains open, concerning household items in the first story public hall. The building has maintained a passing rodent inspection record since 2018, and the recent bedbug filings from 2025 show no evidence of current infestations or eradications. While the property has experienced recurring issues with garbage storage and intermittent heating problems, the relatively recent bedbug and rodent inspections suggest improved pest management practices. However, the building's age and history of maintenance violations indicate ongoing attention to property upkeep may be required.
