45 5th Avenue, Brooklyn, NY 11217
The four-story, nine-unit Old Law Tenement building at 45 5th Avenue in Park Slope, owned by Robert Hamon, has experienced persistent maintenance and health challenges since 2020. The most pressing current issue is an ongoing rat infestation, with the Department of Health documenting violations in January 2025 and confirmed rat activity in March 2025 inspections.
The building has multiple open Housing Maintenance Code violations from 2024, including safety-related issues such as broken ceramic floor tiles in the first-story public hall and concrete paving hazards. Multiple complaints in late 2024 and early 2025 have involved unsanitary conditions, including garbage storage problems and rodent-related issues. The property has a history of infrastructure and maintenance concerns, with multiple Housing Preservation and Development (HPD) inspections in late 2024 revealing various floor and stair issues, though some complaints were closed without violations being found.
In 2023, there were complaints regarding electrical wiring and work without proper permits, though inspections did not confirm violations. Notable open violations from April 2024 include missing required safety notices regarding smoke detectors, carbon monoxide detectors, and gas leak procedures in the common areas. The building's management has experienced repeated difficulties allowing inspectors access, with multiple inspection attempts marked as "Access Denied" or "Unable To Gain Access" in 2019-2020, indicating potential challenges in addressing and resolving violations promptly.
