Zone 0 Is Coming: What Boulder Creek Homeowners Need to Know Before It's the Law
There's a new set of state fire rules working their way toward becoming law, and if you own a home in Boulder Creek, you should know about them now rather than when a compliance letter shows up. It's called Zone 0, and it's going to change what's allowed within five feet of your house.
What Zone 0 Actually Means
Zone 0 is the term for an ember-resistant buffer required within the first five feet surrounding a structure — the zone where wind-blown embers most often ignite a home during a wildfire, long before flames ever arrive. According to the Wildfire and Forest Coalition of America, the rule isn't about creating a bare dirt perimeter. It's about removing materials that spread embers easily — mulch, dry leaves, stacked firewood, wood fencing that touches the house — and replacing them with hardscape, non-combustible fencing, gravel, pavers, or well-maintained fire-resistant plants.
Where the Regulation Actually Stands
This has been years in the making. Assembly Bill 3074 first directed the State Board of Forestry and Fire Protection to draft an ember-resistant zone rule back in 2020, and it's been shaped since by Senate Bill 504, Assembly Bill 1455, and an executive order from Governor Newsom in early 2025. As of April 2026, the Board's subcommittee released an updated draft that notably prioritizes education and outreach over penalties, with a phased implementation approach stretched over five years rather than an immediate hard deadline. Nothing is finalized yet, but the direction is clear enough that waiting to think about it isn't a great strategy.
Why Boulder Creek Specifically Should Pay Attention
This town sits close enough to the CZU burn scar that insurers, county officials, and buyers are already thinking in these terms, whether the regulation is finalized or not. Homes that can already show ember-resistant landscaping tend to quote better on insurance and show better to buyers who've done their homework on fire risk. Waiting for the law to force your hand means you're retrofitting under pressure; getting ahead of it means you're just doing smart landscaping on your own timeline.
What you can start doing now, regardless of the final rule
Move firewood stacks and propane tanks well outside the five-foot perimeter
Replace bark mulch immediately against the foundation with gravel, rock, or pavers
Trim or remove vegetation that touches siding, eaves, or attached wood fencing
Clean gutters and roof valleys of needles and debris — embers land there first

The Honest Tradeoff
I'm not going to pretend this is free or fun. Ripping out mulch beds you've had for years and replacing them with gravel costs money and looks different from the cottage-garden aesthetic a lot of mountain homes lean into. But I've watched too many Boulder Creek families lose everything in 2020 to treat this as optional landscaping advice. This is the kind of tradeoff that's worth naming directly instead of softening: a few thousand dollars in landscaping now, or a much worse conversation with your insurer — or the fire department — later.
If you're weighing whether to tackle Zone 0 work before listing, or want to understand how it might affect a home you're considering buying, I'm glad to talk through it with you.
Note: Zone 0 regulations are still in draft form and subject to change. Verify current requirements with CAL FIRE, the Board of Forestry and Fire Protection, or a licensed contractor before undertaking defensible space work.
