What's driving this score

These are the three data points that most influenced this building's score — ranked by how much weight the model placed on each one.

Number of apartments

The number of residential units affects how the model interprets complaint and violation totals — more units means more potential sources.

Serious violations last 1–2 years

HPD found serious or dangerous conditions at this address recently — the strongest signal of problems ahead.

Building size

Total residential square footage — a proxy for building scale and the number of systems (plumbing, HVAC, etc.) that can fail.
