139 North 9th Street, Brooklyn, NY 11249

The three-story, six-unit tenement building at 139 North 9th Street in Williamsburg, currently owned by Sonaal Mukhopadhyay, has a notable history of maintenance and compliance issues since its 1910 construction. Most concerning is a recent inspection in September 2023 that uncovered violations related to two doors on the first floor public areas that were being held open by permanent stoppers, though these were classified as "Class C" violations and have since been closed.

The building experienced a heat and hot water emergency affecting the entire building in September 2021, though no violations were issued following the HPD inspection. While the building has maintained an active bedbug reporting history from 2021 through 2025, records show consistent reporting with no documented infestations or eradications. Looking back through the building's records, several historical issues stand out, including multiple violations related to door self-closing mechanisms in the late 1990s and early 2000s (specifically in 1999 and 2000), and ventilation issues in a third-floor bathroom reported in 1999.

The building underwent rodent control inspections in 2014, with evidence of rat activity recorded in July and June of that year, though subsequent bait applications were conducted. The regular bedbug reporting from 2019 through 2025 shows proactive management of potential infestations, with all reports indicating zero affected units. The property has generally demonstrated compliance with reporting requirements, though the recent door violation in 2023 indicates occasional lapses in building maintenance procedures.
