Case Study: Leading Home Insurane Company achieves faster, more accurate underwriting with ATTOM

Improving the Underwriting Process with ATTOM’s Building Permit Data

Leading Home Insurane Company faced gaps in its underwriting process caused by difficulty tracking property changes and retrofits, which led to underinsured policies and slower risk assessments. To address this, the firm partnered with ATTOM and adopted ATTOM’s building permit data to get historical and real-time insights into policyholders’ properties.

ATTOM delivered bulk access to more than 200 million building permits, 30+ permit classifiers, real‑time feeds from over 2,000 building departments, and coverage across 94% of top U.S. cities, enabling faster, more accurate risk analysis. With ATTOM’s data the insurer quickly uncovered unreported renovations, proactively updated premiums, reduced time spent sourcing property information, and improved customer trust and satisfaction.
