879 Dekalb Avenue, Brooklyn, NY 11221

879 Dekalb Avenue is a 5-story, 22-unit New Law Tenement building constructed in 1931, currently owned by Alexander Horn. The building has experienced persistent heating and hot water issues, with multiple complaints filed between November 2024 and April 2025, including several violations issued by HPD that required corrections. Notable recent violations include inadequate heat and hot water systems in apartments 2 and 15, as well as a problem with the boiler room door in November 2024.

The building has a troubling history of rat activity, with multiple inspections in 2023-2025 consistently showing evidence of rodents, including recent findings from June 2025 and December 2024. Although there have been no reported bedbug infestations in the past four years (with the most recent reportable period showing zero infested units), the building has faced various maintenance challenges. The property has undergone several local law compliance inspections, with the most recent active inspection related to Local Law 188/17 Compliance as of February 2025.

Past violations from 2020 included electrical and safety concerns, such as improper wiring and a partially obstructed fire escape, though these were resolved with imposed penalties. The building's maintenance record shows ongoing attention to system repairs, with multiple work permits issued between 2019-2020 for electrical and plumbing work. During the period from 2019 through 2025, the building's management has maintained regular compliance with bedbug reporting requirements, consistently showing zero infestation cases, though it should be noted that rodent issues have persisted despite baiting efforts as recent as 2025.
