Open hazardous code violations and surrounding air-quality calls mark a building with indoor maintenance and ventilation friction.
This 76-unit Gramercy rental has stayed under the same family control since 2001, but recent maintenance filings show active code write-ups and building-wide heat drops. Across the three blocks surrounding the building, indoor air quality and food-establishment calls signal commercial venting and odor bleed on the block. Three things to know:
Open hazardous violations for roaches and entry doors remain active. Inspectors issued an open Class C hazardous violation for a roach infestation in June 2026, alongside another write-up for damaged bathroom plaster. That same month, tenants filed four separate pest complaints in four days. Another open Class C violation remains active from July 2026 for a defective self-closing lead door.
Surrounding air quality and food establishment calls point to commercial exhaust bleed. Within three blocks, neighbors filed 21 indoor air quality calls and 10 food establishment complaints over the last year. Restaurant kitchen venting and commercial odor drift travel easily through shared risers or rear airshafts, creating smells that tenants only notice after move-in.
A December cluster of building-wide heat calls signals boiler trouble. Five entire-building heat and hot water complaints hit over two days in mid-December 2025. When complaints cluster like that across multiple hours, it usually points to a central boiler outage rather than an isolated radiator issue in a single unit.
