Augrented Insights Report for 351 Prospect Avenue

The three-story, six-unit residential building at 351 Prospect Avenue in South Slope, owned by Diana Antonaros, has been experiencing recurring maintenance issues over recent years, with particularly concerning patterns related to heat and safety systems.

Most notably, there is currently an active violation (as of September 2024) regarding the failure to file the 2023 external low-pressure inspection report, representing the sixth consecutive year (2018-2023) of missed filings for this required safety inspection. The building's heating system has been problematic, with a recent heat and hot water emergency complaint filed in December 2024 that was unable to be inspected by the Department of Housing Preservation and Development (HPD) due to access issues.

Past complaints show a mix of maintenance challenges, including a September 2021 complaint about unsanitary garbage/recycling storage conditions (which did not result in any violations upon inspection), and a January 2020 rodent-related complaint that was found to have no violations at the time of inspection by the Department of Health and Mental Hygiene. The building's age (constructed in 1931) and classification as an Old Law Tenement are typical for the neighborhood, but the pattern of missed safety inspections and heating system complaints suggests ongoing maintenance oversight issues that could impact resident comfort and safety.
