151 5th Avenue, Brooklyn, NY 11217

151 5th Avenue is a 4-story, 6-unit Old Law Tenement building in Park Slope, Brooklyn, constructed in 1920 and currently owned by Gregory O'Connell. The building has experienced several notable maintenance issues in recent years, with the most recent concern being a heat and hot water complaint from October 2023 that could not be inspected due to access issues. As of October 2023, there are multiple open violations from late October 2023, including concerns about a non-self-closing door in the first-story public hall, missing garbage can covers in the basement area, and the need to remove household articles obstructing public spaces.

The building has demonstrated compliance with bedbug management requirements, with zero infestations reported in the most recent filings from 2025, 2024, 2023, and previous years. While the property has had violations issued for failure to file external low-pressure inspections between 2018-2021, these were ultimately dismissed in May 2025. Historical maintenance records show some rodent inspection challenges in 2018, though subsequent inspections resulted in passing grades.

The building's recent history suggests ongoing maintenance challenges, particularly regarding heating systems and building code compliance. The property has maintained a good track record regarding bedbug management, with consistent reporting showing no infestations. The most pressing current issues, as of October 2023, relate to building safety and maintenance requirements rather than tenant habitability concerns, though the unresolved heat and hot water complaint from October 2023 is notable.
