149 Prospect Avenue, Brooklyn, NY 11215

149 Prospect Avenue is a two-family house located in Gowanus, built in 1899 and currently owned by Sadah Althaibani. The property has experienced several significant issues over the past few years, particularly relating to illegal conversions and safety violations. Most recently, in October 2024, the building received an active ECB violation for removing or defacing a written posted vacate order from 2017 regarding the basement level, resulting in a $2,500 penalty.

This violation remains unresolved as of October 2023. The building has a documented history of heat and hot water complaints, with an emergency report in October 2018 involving the entire building, though inspectors were unable to gain access to verify the conditions. Between 2020 and 2024, there were multiple complaints regarding illegal conversions at the property, with three separate entries between May 2020 and October 2024, though in all cases, inspectors were unable to gain access on multiple final attempts.

The most recent illegal conversion complaint from October 2024 did result in an Oath Violation being served. These persistent access issues during inspections suggest potential ongoing concerns regarding building conditions and compliance with housing regulations. The property’s historical documentation indicates these unresolved compliance issues may impact resident safety and comfort, particularly regarding the building's heat/hot water systems and unauthorized modifications.
