838 Jefferson Avenue, Brooklyn, NY 11221

838 Jefferson Avenue is a 4-story, 8-unit New Law tenement building constructed in 1910 in the Bedford-Stuyvesant neighborhood, currently owned by Benjamin Cavicchio. The property has experienced recurring maintenance issues over recent years, with the most significant concerns emerging in 2024 and 2025. In September 2024, multiple violations were documented affecting apartment 3R, including problems with heat and hot water, water leaks in the bathroom, pest infestations (specifically roaches), and issues with maintenance, including broken plaster surfaces and defective paint in the bathroom.

The building has also experienced intermittent heat and hot water problems, with emergency complaints filed in February and September 2024, and multiple door-related issues in June 2025. Of particular concern is the recent rodent activity reported in June 2025, following previous rat sightings and violations in 2021-2022. While there have been no reported bedbug infestations in recent years (with the most recent reports from 2024 showing zero infested dwelling units), the building's maintenance record shows a pattern of recurring issues requiring attention.

The property has open violations as of September 2024, including problems with self-closing doors, encumbrances in public hallways, and access to the heating system. Recent 311 complaints have been investigated by HPD, though not all have resulted in violations. The building's permit history shows issuance of two permits in May 2019, though details of the work conducted under these permits are not specified in the available data.
