Augrented Insights Report for 21 Adelphi Street

21 Adelphi Street in Fort Greene is a 4-story, 8-unit New Law Tenement built in 1915 and currently owned by Mariam Farooq. The building has experienced several significant maintenance issues in recent years, particularly in apartment 4L, which was cited for multiple violations in December 2024 including inadequate heat supply (Class C, Open), missing smoke detector (Class B, Open), missing carbon monoxide detector (Class B, Open), defective self-closing door (Class B, Open), and various other maintenance issues.

Most recently, in January 2025, there were additional complaints about heat and hot water problems, though these were reportedly corrected according to HPD. The building has active ECB violations from June 2023 regarding unpermitted work and construction that does not conform to approved documents, with penalties totaling $2,500. There are also several other open violations, including failure to file annual boiler inspection reports for 2018 and 2019.

A work without permit complaint from June 2023 was previously closed with a stop work order fully rescinded. The property has maintained a clean record regarding bedbug infestations, with no reported cases in the past two monitoring periods (2021-2022 and 2022-2023). While there have been multiple quality of life complaints through 311, most have been addressed or closed, though some remain active as of the latest reports.
