Avoid these NYC building red flags
You do not need a viral “worst buildings” list — you need a checklist that works on any address.
RentersFax flags the same signals inspectors and 311 already logged: open hazardous violations, pest clusters, and heat outage winters.
Treat open Class C (immediately hazardous) records as a hard stop until the landlord documents closure. Closed historical violations matter less than what is still open.
Also watch portfolio size: a thin LLC managing dozens of buildings with repeated heat or pest filings is a pattern, not a one-off bad week.
- Open Class C (immediately hazardous) violations
- Repeated heat/hot-water complaints across a winter
- Pest complaints spanning multiple floors
- Large LLC portfolios with thin on-site accountability
