To help homeowners navigate that uncertainty, Zillow is adding a climate risk threat score to every for-sale listing on its platform. Data from First Street Foundation, a nonprofit that assesses climate risk, will provide home buyers with scores that measure each property’s susceptibility to flood, wildfire, wind, heat and air quality risks. This information will be available on the Zillow app for iOS and website by the end of this year, while Android users will be able to access the data in early 2025, the company said in a release last month.
