Wildfire Prepared Home Plus™

Building on the requirements of Wildfire Prepared Home, which identifies critical components that must be addressed to reduce wildfire risk, Wildfire Prepared Home Plus goes further to address additional areas of the home that are vulnerable to provide even greater protection. Based on the latest wildfire mitigation science, these actions, when taken together, can further reduce the likelihood embers will ignite your home.

While you can’t eliminate all wildfire risk, Wildfire Prepared Home Plus makes it easy to understand which actions can give your home an even better chance against wildfire.


Includes mitigation actions identified in Wildfire Prepared Home, such as having a Class A roof, plus additional guidance for gutters and eaves.


Addresses building features identified in Wildfire Prepared Home, such as vents, plus additional components like noncombustible siding and exterior doors, fire-resistant windows, and more.


In addition to maintaining the 5-foot Home Ignition Zone identified in Wildfire Prepared Home, upgrading to a noncombustible deck, removing back-to-back fencing, and moving accessory structures 30 feet from the home is required.

Typical Homes Are Vulnerable to Wildfire

We spent years studying how flames and embers ignite homes during a wildfire and have identified mitigation actions that reduce the chance a home will be ignited. These actions comprise the requirements of Wildfire Prepared Home and when taken together give your home better protection against wildfire.
