AI summary · updated June 2026

The 4-story, 4-unit tenement building at 48 Marcy Avenue in Williamsburg, built in 1910 and currently owned by Marcy Canaj LLC, has experienced several notable issues in recent years. The most significant cluster of problems occurred in early 2021, when there were multiple complaints (eight in total between February 20 and March 4) regarding building-wide heat and hot water issues, all of which resulted in violations. More recently, in 2024, the building received multiple violations related to safety concerns, including issues with self-closing doors at the cellar entrance and apartments, as well as a key-operated lock on a fire escape window in apartment 3R. An emergency violation for a missing carbon monoxide detector in apartment 4 was also recorded in 2021.

The building's history includes several Department of Buildings complaints regarding work without proper permits, with the most recent being in 2022 and resulting in a $1,250 penalty for unauthorized interior renovation work in apartment 1A. There were also multiple complaints between 2019 and 2022 regarding various potential safety concerns, including wall condition and illegal conversions, though inspections were often unable to gain access to verify these issues. However, the building has demonstrated good pest management practices, with no reported bedbug infestations in the past four reporting periods from 2021 through 2025, and rodent inspections showing improved compliance with passing results in 2019 and 2012. The most recent bedbug report from May 2025 indicates no current infestations or extermination activity, suggesting effective pest control measures.
