Why building details matter

A street-address score can account for the unique characteristics of a specific building, including age, construction type, roof shape and condition, occupancy, elevation, defensible space, drainage, terrain, and nearby exposure. Those details can change resilience or susceptibility around the same location-level score.

Use this county page as the broadest browse layer before drilling into city and ZIP pages. Since the percentile is elevated, it is worth comparing nearby pages before relying on the area score alone.

Use the PerilScore app to enter a street address and see the full property-specific score.
