5023 4th Avenue, Brooklyn, NY 11220
This 6-unit, 4-story New Law tenement building located at 5023 4th Avenue in Sunset Park, owned by Frank Iuliano and constructed in 1931, has experienced several recurring maintenance issues in recent years, particularly regarding heat and hot water systems. Between 2022 and mid-2025, there have been multiple complaints and service requests related to heat and hot water outages affecting the entire building, three of which occurred in 2023-2024, though inspections often faced access issues and did not result in violations.
More recently, in 2025, there was a food safety complaint currently under investigation by the Department of Health. The building has also faced several compliance challenges, with five active violations as of June 2023 regarding failure to file External Low Pressure Inspections from 2018-2022, and past issues with fire escape obstruction and unauthorized electrical work that resulted in environmental control board violations in 2021.
The property has maintained a good record regarding pest control, with no reported bedbug infestations in the past five years, and most recent rodent inspections in 2022 showing both rat activity and successful bait application efforts, though a 2022 rodent complaint was eventually resolved. Historical complaints show varied access issues for inspectors, including a 2020 electrical lighting complaint and multiple instances where housing preservation inspectors could not gain access to verify heating system functionality. The building's maintenance history suggests ongoing challenges with heating infrastructure, though recent bedbug and pest control records indicate better management of these issues.
