Augrented Insights Report for 4820 4th Avenue

The 17-unit, 4-story tenement building at 4820 4th Avenue in Sunset Park, built in 1904 and currently owned by Alessandro Pirozzi, has experienced several maintenance and hygiene issues in recent years, with the most pressing concerns emerging in late 2023 and early 2024. A significant incident occurred in November 2023 when the entire building experienced heat and hot water outages, though these services were reportedly restored quickly. More concerning was the emergence of mold and water-related maintenance issues identified in late 2023, including problems with the roof, visible mold in the 4th-story public hall ceiling, and various public hallway maintenance deficiencies.

The building has also faced periodic rodent control challenges, with multiple complaints documented between 2022 and 2024, though a compliance inspection in May 2024 resulted in a passing grade. Other notable issues include a plumbing problem in January 2025, which was promptly addressed, and multiple complaints about work being done without proper permits in 2023-2025, though inspectors were unable to gain access during two attempts in May 2025. The building's environmental health record shows regular inspection requirements being met for pests, with no documented cases of bedbug infestations between 2019 and 2025.

The property is in compliance with recent bedbug reporting requirements, showing zero infested units during the most recent reporting periods. Historical records from 2018 indicate a gas system violation related to missing vent limiter equipment which was resolved, and various housing maintenance code violations were documented and addressed in late 2023, including requirements related to gas leak safety procedures and the need for proper maintenance of fire-retardant ceilings. While the building has faced various maintenance challenges over the years, records indicate that most violations are addressed, though some issues from late 2023 regarding painting requirements in public areas remain open as of early 2024.
