154 North 9th Street, Brooklyn, NY 11249
154 North 9th Street is a 5-unit, 3-story residential building located in Williamsburg, Brooklyn, owned by Maxwell Seibald and constructed in 1910 as an Old Law Tenement. The building has experienced several significant issues in recent years, most notably a concerning cluster of problems in late 2021. During this period, multiple complaints were filed regarding heat and hot water outages affecting the entire building, unsanitary conditions including pest infestations, mold, and inadequate garbage/recycling storage, as well as general maintenance issues with the bell/buzzer/intercom system.
While some of these complaints were resolved, access issues during HPD inspections complicated matters. The building underwent a significant incident in October 2021 involving fire damage in apartment 2L, which resulted in several violations that were later certified as corrected in early 2023. There were also structural and safety concerns identified in December 2022, including defective self-closing doors, issues with fire escape ladders, and concerns about fire-rated materials at the scuttle opening on the third story. More recently, the property has faced difficulties with its external low-pressure inspections, with active violations issued in June 2023 for failure to file 2019-2021 inspection reports.
However, as of July 2025, the building has maintained a clean bedbug record over the past two reporting periods (2023-2024 and 2024-2025) with no documented infestations. A notice of violation for occupancy during repairs was issued in 2022-2023 regarding apartment 2L, though this was fully rescinded in May 2025. While the building has demonstrated some recent improvements, particularly in pest management and bedbug reporting compliance, the pattern of service requests and violations between 2021-2023 indicates historical challenges with building maintenance and resident services. The property currently has several unresolved violations related to external low-pressure inspections from 2019-2021.
