Wildfire Risk Assessment & Home Hardening ROI Analysis
Wildfire Risk Overview
San Juan County in Colorado is in the 76th percentile nationally for risk to homes, the high risk category. San Juan County's mean risk to homes ranks at the 76th percentile of U.S. counties: at or above 76% of them (USDA Forest Service, Wildfire Risk to Communities). This is a rank among counties, not a dollar loss.
San Juan County's mean annual burn probability is at or above 64% of U.S. counties (national percentile rank, USDA Forest Service, Wildfire Risk to Communities). A percentile rank compares counties with one another. It is not the chance that a fire reaches a home in a given year. San Juan County's mean annual burn probability is 0.10% a year: the average across its wildfire-exposed land (USDA Forest Service, Wildfire Risk to Communities, 2026 county summary). It is a county figure, not a forecast for any one home. About 0% of the county's buildings sit in the minimal-exposure zone, where the chance is lower.

Data Sources & Methodology
Burn probability and the national percentile ranks come from the USFS Wildfire Risk to Communities (WRC) county summary, 2026 release (doi.org/10.2737/RDS-2024-0030). Fire hazard severity zones are from CalFire FRAP. Insurance discount estimates follow the California Department of Insurance Safer from Wildfires framework. Hardening cost estimates are reference ranges informed by IBHS guidance with a regional cost multiplier; they are estimates, not contractor quotes. Financial projections use a discount rate based on the 10-year Treasury yield and an insurance price inflation assumption; each paid answer reports the exact rates it used. All calculations are deterministic with no AI-generated content.
