If you own a home in the Sierra foothills, Tahoe or anywhere near wildland in California, you’ve probably heard the term “Zone Zero.” It’s showing up in the news, in fire department notices and, more and more, in conversations with insurance underwriters. Here’s what it is, where the rules stand today, and what it means for your insurance.
What is Zone Zero?
Zone Zero, also called Zone 0 or the ember-resistant zone, is the first five feet around your home, measured from the outside walls and including attached decks, stairs and similar structures.
California already has two defensible space zones you may know: Zone 1 (5 to 30 feet from the home) and Zone 2 (30 to 100 feet). Zone Zero is the newest and strictest, and for good reason. Most homes lost in wildfires aren’t touched by a wall of flames. They’re ignited by embers that blow ahead of the fire and land in dry mulch, leaves, a woodpile or a wooden fence right against the house. Zone Zero is about making sure that when embers land, there’s nothing there to catch.
Where the rules stand right now (October 2026)
This is where a lot of people are confused, so let me lay it out plainly:
- 2020: State law (AB 3074) created the five-foot ember-resistant zone and directed the Board of Forestry to write the detailed rules.
- August 19, 2026: The California Board of Forestry and Fire Protection voted unanimously to adopt Zone 0 regulations.
- September 8, 2026: The Board withdrew the package from final state legal review to make technical edits. It has not been abandoned, and another public comment period is expected.
- Today: The statewide Zone 0 rules are not yet in effect, and no effective date has been set. Zone 1 and Zone 2 rules remain in effect. Some cities and fire districts have adopted their own Zone 0 ordinances, so check with your local fire agency.
I’ll update this post when the rules are finalized.
Who it will apply to
As adopted in August, the rules would apply to homes in the State Responsibility Area (areas where CAL FIRE is responsible for wildfire protection) and in Very High Fire Hazard Severity Zones in cities and other local areas. That covers a large share of homes in the Sierra foothills, Gold Country and North Bay counties we serve. You can look up your address on CAL FIRE’s Fire Hazard Severity Zone map.
What Zone Zero would require
Within five feet of your home, attached deck, stairs or pergola, the adopted draft would require you to:
- Remove combustible ground cover, including bark, mulch, wood chips, dead leaves and pine needles.
- Keep roofs and gutters clean of leaves and needles.
- Move firewood out of Zone Zero.
- Clear underneath decks, balconies and stairs.
- Deal with wood fencing. No new combustible fencing in Zone Zero, and existing wood fences that attach to the house need a noncombustible section where they connect.
- Limit outbuildings. Sheds and similar structures in Zone Zero would have to be entirely noncombustible.
- Keep plants limited and well-maintained. Some low, non-woody plants would be allowed if they meet height and spacing standards, but no plants in the first foot from the home.
How much time homeowners would have
New construction would have to comply as soon as the rules take effect. Existing homes would phase in:
- Phase 1 (within 3 years): Remove combustibles like mulch, firewood, leaves and wood chips; clean gutters; remove dead and dying plants; trim trees; and adjust plantings.
- Phase 2 (within 5 years): Local agencies set a timeline for creating an under-eave safety zone, replacing combustible gates, and adjusting sheds and fencing.
Requirements that were already state law, like clean roofs and gutters and clearing dead branches, apply right away.
Why Zone Zero matters for your insurance
Here’s the part I care about most as your broker. You don’t have to wait for the state to finalize anything to benefit.
1. It can earn you discounts today
Under the California Department of Insurance’s Safer from Wildfires regulation, admitted insurers must offer discounts for specific mitigation steps, and a five-foot ember-resistant zone is one of them. Other qualifying steps include ember-resistant vents, a Class A fire-rated roof, six inches of noncombustible material at the base of exterior walls, and Zone 1 and 2 defensible space. The Insurance Commissioner has said discounts across the full program can range from about 4% to more than 40% of premium, depending on the home and the combination of measures completed.
2. It can help you qualify for coverage
Underwriters look closely at what’s right up against the house. A clean Zone Zero, along with good defensible space, can make the difference in whether a carrier will write your home at all, or whether it gets a credit or a debit when the underwriter prices it.
3. Compliance isn’t a guarantee
To be straight with you: meeting the Zone Zero standard doesn’t force any insurance company to offer you a policy or a specific discount. Every carrier has its own underwriting guidelines, and each one recognizes and documents mitigation a little differently. That’s exactly why it pays to have someone who knows those guidelines carrier by carrier.
Your Zone Zero checklist: start this weekend
Most of this costs little or nothing:
- Rake out bark, mulch, needles and leaves from the five feet around your home. Replace them with gravel, pavers, concrete or bare soil.
- Clean your roof and gutters, and keep them clean through fire season.
- Move firewood, lumber, trash cans and propane tanks at least five feet from the house.
- Clear out anything stored under your deck or stairs.
- Remove dead plants, and trim branches back so nothing hangs over the roof.
- Look at where your wood fence meets the house. A metal gate or masonry section at the connection makes a big difference.
- Take dated photos of your work. Many carriers ask for documentation to apply mitigation discounts.
Let’s make sure you’re getting credit for it
If you’ve already done the work, or you’re planning to, let’s make sure your insurance reflects it. We’ll review which mitigation steps your carrier recognizes, what documentation they need, and whether a different carrier would reward your efforts more.
