173 Jefferson Street, Brooklyn, NY 11206

173 Jefferson Street is a 2-story, 5-unit mixed-use building in Bushwick, constructed in 1931 and currently owned by Chaskel Landau. The property has experienced recurring maintenance issues over the past several years, with multiple complaints related to water leaks, mold, and heating systems. Most notably, between November 2020 and April 2021, the building faced significant challenges with heavy water leaks, plumbing issues (including toilet problems), and electrical concerns.

During this same period, there were also complaints about unsanitary conditions, a fire escape safety concern, and heating/hot water problems affecting both individual apartments and the entire building. More recently, in 2025, a mold-related complaint was filed and closed within two weeks. The building has undergone some scrutiny from regulatory agencies, including a 2023 investigation into construction safety compliance and a period of illegal after-hours work, though no violations were confirmed in the latter case.

The building's maintenance history shows a pattern of responsiveness to complaints, with the Department of Housing Preservation and Development (HPD) conducting inspections and addressing reported issues, though access challenges sometimes prevented full inspections. The property appears to have maintained reasonable compliance with bedbug regulations, with no reported infestations in the most recent filing period from November 2023 to October 2024. An earlier investigation into an alleged illegal conversion of the property in 2019 was marked by access issues during inspection attempts in 2020, and the complaint was ultimately classified as "No Access – 2nd Attempt." While the building has demonstrated ongoing challenges with basic maintenance and infrastructure systems, particularly during the 2020-2021 period, more recent complaints have been less frequent, though a pattern of mold-related issues persists.
