Cost estimates are based on the Headwaters Economics report, The cost of retrofitting a home for wildfire resistance, produced in 2024 in partnership with CAL FIRE and adjusted for inflation. Most costs are derived from RSMeans, a national database for the construction industry. Additional cost estimates were procured from suppliers, construction industry experts, or manufacturers. Unless otherwise noted, costs include labor and materials for demolition of non-fire-resistant components and replacement with fire-resistant options.
Costs are updated for inflation annually. The tool was last updated in June of 2025.
Many fire departments and state fire agencies will provide free home assessments and recommendations.

About Defensible Space
How can I create defensible space?
Together with fire-resistant building materials, defensible space significantly improves your home’s chance of surviving a wildfire. To create defensible space around your home, start by clearing all flammable material—including vegetation, dry leaves, and pine needles—from your roof, gutters, decks, and the ground within 5 feet of the house. Trim branches and limit the storage of combustible items in this area. This 0–5 foot zone—sometimes called Zone 0 or the noncombustible zone—is the most critical area to keep free of anything that can catch fire.
In the 5–30 foot zone, create a separation of at least 10 feet between trees, shrubs, and other items that could catch fire. Regularly trim branches to at least 6 feet off the ground—more in areas with steep slopes or shrubs. Keep grass trimmed low. Choose fire-resistant plants and maintain them well.
From 30–100 feet, reduce the density of trees and brush to slow fire spread. Mow grass regularly.
