Augrented Insights
AI summary · updated June 2026

The three-unit residential building at 4604 Fort Hamilton Parkway in Borough Park, owned by Joseph Alonzo, has experienced several notable events over the past few years that warrant attention. Most recently, in March 2024, there was a sewage leak incident that required investigation by the Department of Health and Mental Hygiene, though no health code violations or hazards were found in that case. The building has been consistently cited for failing to file the mandatory annual bedbug reports as required by Housing Maintenance Code, with four consecutive open violations documented between 2021 and 2024. These violations represent a pattern of non-compliance over multiple years, indicating ongoing oversight in addressing this specific regulatory requirement. The building, constructed in 1910, was classified as "Converted Class A" and has three stories, though the age of the building itself does not immediately suggest any particular concern.
