515 Ralph Avenue, Brooklyn, NY 11233

The three-story, three-unit residential building at 515 Ralph Avenue in Crown Heights, owned by Norris Joslyn, has experienced several notable maintenance issues since its construction in 2008. The most recent incident occurred in May 2025, involving indoor air quality concerns related to chemical vapors, though this complaint was closed quickly after the condition was reported to no longer exist.

A series of water-related problems characterized the building's maintenance history, with multiple reports between 2021 and 2022. Four separate water leak complaints were filed with the Department of Housing Preservation and Development (HPD) in 2022 alone, describing issues including slow leaks and damp spots. While violations were issued for one of the 2021 complaints following an inspection, many of these complaints were closed without access being granted for inspection, and the HPD specifically noted in several cases that if the conditions persisted, new complaints should be filed.

The building's documented issues suggest a particular pattern of water-related concerns, especially notable during 2021-2022, though there have been no recorded water-related complaints since September 2022. The most recent air quality complaint from 2025 indicates some ongoing maintenance monitoring, though this was resolved quickly. The property has maintained compliance with closing out the majority of complaints, though many required residents to refile complaints rather than being fully resolved through inspection and remediation.
