How can you start creating defensible space around your home?

There’s no one-size-fits all homeowner’s checklist for this process, because every home and property is a bit different.

If you want to be thorough and ensure you’re doing everything you can to defend your home from a wildfire, contact us at Ember Defense at (415) 573-2400 today. We’ll schedule a visit to your property so our experts can evaluate your current defensible space and give recommendations on how to mitigate your wildfire risk.

Some top resources for more information about defensible space include the informative website of Cal fire (also known as the Department of Forestry and Fire Protection) which can be found at, the website for Fire Safe Marin, and your local fire department. We’ve also got a wealth of helpful tips to share here, so read on to gain a basic understanding of fire safety and preparedness when it comes to the area around your property.

Know Your Defensible Space Zones breaks down defensible space into three key zones, all of which require different care and techniques to be as fire-resistant as possible. Collectively, they’re known as the home ignition zone. Broken down, they are:


The Immediate Zone

Which includes the home itself plus the area the closest to the home—within five feet. This is the defensible space zone that should get the most fire-protection attention, because it’s the most vulnerable.


The Intermediate Zone

Which is the zone that begins where the immediate zone ends and extends out thirty feet from there. This area typically consists of landscaping.


The Extended Zone

Which begins where the intermediate zone ends and extends out up to 200 feet. Of course, not all property owners have property lines that go out this far, but it’s important for those that do to include all of this area in their defensible space too.

Start with the house itself

As mentioned above, your house is included in the immediate zone. Start there. Clean out your gutters and set a reminder for yourself to do so regularly to prevent buildup of combustible materials like pine needles. Keep any wood piles and propane tanks away from the home in a fire-resistant enclosure. Make sure all of your windows, window screens, and roof tiles or shingles are intact, and replace any of the above if needed to prevent the entry of embers. To that end, you should also get the vents on your home replaced with the ember-resistant variety. After all, as many as nine out of ten homes destroyed by wildfires ignited because of embers blown by the wind.

Use Landscaping That's Fire-Resistant

In the intermediate and extended zones, it’s crucial to make sure that any landscaping materials you use are fire-resistant. Any types of flammable vegetation should be avoided; refer to the tips for choosing fire-resistant plants on the website. You should make sure your trees and shrubs are properly spaced, too, to prevent them all from igniting if one does. Refer to the Firewise guidelines on spacing for this. Finally, you should also use inorganic mulch like gravel or brick chips (as opposed to organic mulch like bark or shredded rubber), since it’s less likely to burn.

Keep Up with Yard Maintenance

Yard maintenance is all about fuel reduction—that is, making it so that a wildfire has less kindling if it should pass through your property, so it has a harder time spreading. You should stick to a frequent schedule for clearing out any dead plants from your yard and prune any dead pieces from healthy plants, as these can all present a fire hazard. Make sure to also mow your seasonal grasses and limb up all vegetation touching the ground before the beginning of each fire season.
