How we score buildings

How 521 West Street's risk score is calculated

Risk factors

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.

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.

Number of apartments

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