363 Grand Avenue, Brooklyn, NY 11238

363 Grand Avenue is a 6-story, 25-unit Old Law Tenement building in Clinton Hill, constructed in 1887 and currently owned by Peter Armstrong. The property has experienced ongoing maintenance challenges in recent years, most notably a building-wide heat and hot water outage in May 2025, which followed a pattern of similar heating issues.

The building has persistent elevator problems, with multiple complaints about single device service and no alternate service between 2019 and 2025, though inspections often found no violations. Additional concerns include recurring rodent activity, with multiple inspections between 2023 and 2025 showing rat activity, and unsanitary conditions related to garbage and recycling storage. The building has documented violations requiring attention to safety features, including multiple issues with self-closing doors in 1st story common areas and Apartment 3B, as well as problems with smoke and carbon monoxide detectors in 2024.

Structural and maintenance issues have been noted, including rotting decorative wood trim on the 6th floor (2024), problems with the building's facade and parapet wall (2021), and various interior maintenance needs in Apartment 3B, such as bathroom plumbing issues and water leak problems. While the building's bedbug reports between 2021 and 2024 show no infestations, the rodent inspection results suggest ongoing pest management challenges. The property has also faced some compliance issues with various building codes and maintenance requirements, as evidenced by multiple Department of Buildings violations and Environmental Control Board violations, though many of these have been resolved through proper remediation.
