6406 20th Avenue, Brooklyn, NY 11204

6406 20th Avenue in Borough Park is a 3-unit, 3-story building constructed in 1931, currently owned by Maria Montalbano. The property has experienced several maintenance issues in recent years, with the most recent problems occurring in April 2025 involving electrical lighting issues and wall paint/plaster concerns.

A significant cluster of complaints emerged in December 2023, including multiple access denial situations where HPD was unable to inspect reported problems, including issues with radiators, intercom systems, wall conditions, window frames, heating systems, and both smoke and carbon monoxide detectors. These conditions raised various safety and maintenance concerns for the residents. The building's history shows documented violations related to the failure to certify corrections on immediately hazardous (Class 1) ECB violations in late 2019, though these were ultimately dismissed in 2020.

The property has had some infrastructure concerns, including a boiler issue in 2021 and a construction enforcement matter in 2019, with appropriate violations served. An inspection in October 2024 found no significant issues with bulging or cracked walls, and the building's bedbug reporting history from 2022-2024 shows no infestations or related problems, suggesting successful pest management. While the property has experienced various maintenance challenges, most recent violations have been addressed through HPD inspections, though the pattern of access denial remains concerning from a tenant perspective.
