Climate risk analytics · First Street
First Street
Climate risk data provider best known for property-level flood, wildfire, wind and heat risk scores across US real estate.
First Street models property-level climate risk -- flood, wildfire, wind, heat and air quality -- across every property in the United States, with 30-year projections that account for a changing climate rather than only historical baselines. It reaches consumers through its free public Risk Factor lookup tool and generates revenue through a commercial API and bulk data licensing arm used by real estate listing portals, mortgage lenders, insurers and government agencies. Its parcel-level US coverage and peer-reviewed methodology distinguish it from broader but coarser global providers, making it a common default source for US property climate-risk disclosure and underwriting.
