Bad apartments don't announce themselves. Here's what waits for the renters who didn't look.
That fresh coat of paint is covering something. The city might have filed a dozen building code violations in the last two years — unresolved, unfixed. The listing won't mention them. Your landlord won't either. Once you've signed, you're their tenant, not their problem to impress.
Once you've signed, breaking the lease costs thousands. Knowing before costs nothing.
There are landlords in NYC who own 30+ buildings with hundreds of open complaints across them — and keep doing it because most renters check one building without knowing about the other 29. A pattern that's invisible from one address is obvious when you see the whole portfolio.
One bad landlord can mean 12 months of ignored repairs, withheld deposits, and legal headaches.
The permit history, violation record, 311 complaint log, fire incident reports — all public record. Just scattered across 15 different city databases that no individual has time to query. So most renters sign on information that's available but inaccessible.
We pull all of it. You read one report.
What you get
Our machine learning model analyzes every building's trajectory — not just its current violations — and predicts the likelihood of future code violations up to 12 months in advance. A building that's been clean for 10 years and started slipping two years ago is a different risk than one that's been consistent. You'd never know the difference without this.
We pull from 50+ government databases and connect permits, violations, complaints, fire incidents, 311 calls, and more — so you don't have to. Not just the last 6 months. The full history.

A building is only as good as the person managing it. We surface real owner names, contact info, and every other property in their portfolio — so patterns that were invisible from one address become unmistakable.
Read reviews from verified tenants, flag unhelpful ones, and contribute your own experience after you move in. The public record shows what was filed. Tenants tell you what it was like to actually live through it.
"Checked the building before signing. Report flagged some older heat complaints — I asked the landlord directly, they'd replaced the boiler last year. 18 months in, no issues. Checking first changed how I negotiated."
