420 Union Avenue, Brooklyn, NY 11211

The three-story, six-unit tenement building at 420 Union Avenue in Williamsburg, owned by Fabrizio Manganiello, has experienced several maintenance issues in recent years. Most notably, in April 2025, there were two emergency plumbing complaints regarding a basin/sink and a bathtub/shower, though both were closed within one month after HPD confirmed the issues were corrected.

The building is subject to annual bedbug reporting requirements, and records show consistent compliance with zero reported cases of infestation or re-infestation from 2018 through the most recent 2024 report. An inspection in March 2022 noted a violation regarding the timely filing of the annual bedbug report, though this appears to have been rectified in subsequent years. The building's maintenance history reveals some concerns with pest control, particularly in early 2018 when rat activity was recorded in three consecutive inspections between December 2017 and February 2018.

A general failure to maintain complaint was filed in November 2021, but this was investigated and resulted in no violations being warranted. While the property has experienced periodic maintenance issues, particularly with plumbing systems as evidenced by the 2025 complaints, there is currently no active litigation or major unresolved violations on record. The building's age and old law tenement classification suggest it has maintained compliance with many of the city's regulatory requirements over the years, including regular bedbug reporting demonstrating a commitment to pest management.
