Active pest citations, six open class-C violations, and indoor air quality complaints make this Washington Heights walk-up one to inspect carefully before signing.
A 20-unit Washington Heights walk-up built in 1911, carrying six open immediately hazardous class-C citations for pests, self-closing doors, and lead paperwork. The surrounding block also carries a heavy street-noise footprint. Three things to know:
Indoor air quality calls point to potential riser bleed or ventilation gaps. Two indoor air quality calls were logged directly for the building, indicating air-shaft or riser bleed issues that are impossible to spot during a quick walk-through. In a 1911 walk-up, air quality filings typically stem from kitchen venting or baseline ventilation gaps across lines.
Six open immediately hazardous citations cover active pests and fire-safety doors. The building carries six open class-C immediately hazardous violations. Recent citations include open rat, mouse, and roach infestations, defective self-closing doors, and uncertified lead-paint compliance records for vacant units.
