The building carries three open safety violations while air quality and parking calls cluster along Tenth Avenue.
The building carries three open housing violations, including an immediately hazardous entry-door defect, alongside a brief midwinter heat drop. Beyond the building's own walls, Tenth Avenue commercial activity generates noticeable air quality and street-level noise. Three things to know:
Three open violations target basic unit door and detector hardware. Inspectors cited the building in February 2026 for a defective self-closing entry door in Apt 3FN, categorized as immediately hazardous. Two Class B violations followed in July 2026 for missing or non-functional smoke and carbon monoxide detectors.
Food establishment venting and air quality calls cluster along the avenue. Within three blocks of the building over the past year, records show 18 food establishment complaints and 14 indoor air quality reports, alongside an indoor air quality complaint lodged directly against this address in July 2025. These signals typically point to restaurant exhaust or riser-driven odor migration into residential spaces.
Building-wide heat calls flared during a cold spell in January 2026. Three building-wide heat complaints were logged over an eight-day stretch in January 2026. While the cases are now marked closed, the concentrated cluster indicates the heating system struggled during peak winter cold.
