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.

Number of apartments

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

Building size

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

Neighborhood location

The model uses precise location as a proxy for neighborhood-level risk patterns — some blocks have systematically higher violation rates.
