403 Carlton Avenue, Brooklyn, NY 11238

403 Carlton Avenue is a 4-story, 1930 brick building located in Fort Greene, currently owned by National Long Term Care Associates LLC. The building has experienced recurring heating system issues, with multiple complaints about inadequate heat recorded between 2019-2024, including a significant whole-building outage in January 2019 and both apartment-specific and building-wide heat problems later that year.

The elevator system has required significant attention, with multiple violations documented in 2018-2020 regarding safety features, maintenance, and operational issues. These included serious concerns such as worn hoistway door gibs, oil leaks, and malfunctioning door restrictors, resulting in Environmental Control Board penalties totaling $2,500. More recently, as of June 2023, the building has active violations for failing to file required external low-pressure inspections for 2018-2019, and there have been persistent rodent-related challenges, with multiple inspections between 2015-2025 indicating rat activity.

While there have been various permits issued for elevator work and other maintenance (most notably in 2019-2020), the building's record shows ongoing maintenance challenges. The most recent complaint history suggests some improvement, with a passed compliance inspection in January 2025, though this follows several consecutive years of rat activity reports in 2024. The building has had three heat-related complaints in 2019 alone, with at least one requiring emergency intervention, and there were several building-system-related complaints including boiler and debris concerns in previous years, though these were mostly resolved without formal violations.
