Zone 0 landscaping means rethinking the first five feet around your home so nothing in it can catch an ember. Under AB 3074 and California’s defensible space law (PRC 4291), the 0-to-5-foot ember-resistant zone shifts from decorative planting to noncombustible, low-maintenance ground — gravel, stone, and carefully limited greenery. Done right, it still looks intentional and clean; it just refuses to burn. Here is exactly how to landscape the ember-resistant zone in California.

The Core Rule of Zone 0 Landscaping
The guiding principle is simple: within five feet of the house, deck, or attached structure, remove combustible material and replace it with something an ember cannot ignite.
That reframes the whole design. Instead of foundation shrubs and bark beds, zone 0 landscaping uses hardscape and mineral ground cover as the default, with plants treated as the rare exception rather than the rule.
What to Remove From the First Five Feet
Start by clearing the combustibles most homeowners never think of as fuel.
- Bark, wood-chip, and shredded-rubber mulch — the single most common Zone 0 ignition source.
- Shrubs, ornamental grasses, and dense groundcover against the foundation.
- Climbing vines on walls and fences.
- Dead leaves and needles collecting in beds, on the roof, and in gutters.
- Firewood, lumber, and combustible planters or furniture along the wall.
Why bark mulch is the first thing to go
Bark and wood mulch are essentially designed to smolder — they hold heat and reignite. A bed of it against your siding is the easiest way for a landed ember to become a house fire. Gravel or decomposed granite gives the same finished look with none of the risk.
What to Use Instead: Noncombustible Ground
Good zone 0 landscaping leans on materials that read as designed, not barren.
- Gravel, crushed rock, and decomposed granite in varied tones.
- Pavers, flagstone, brick, and poured concrete.
- Boulders and dry-stack stone as focal features.
- Bare, compacted mineral soil where nothing else is needed.
These materials double as a clean maintenance strip that keeps weeds and debris away from the foundation year-round.
Plants in Zone 0: Keep It Minimal
The draft standard for the ember-resistant zone strongly favors a plant-free band. If you keep any greenery in the first five feet, follow strict limits.
- Low-growing and widely spaced — no continuous vegetation.
- High-moisture, well-irrigated succulents or groundcover, never woody shrubs.
- Nothing touching the siding, windows, or eaves.
- No plants directly beneath vents or under decks.
When in doubt, move the planting bed out past five feet into Zone 1, where “lean, clean, and green” landscaping is the standard.
The most fire-smart plant choice is fewer plants
There is no such thing as a truly “fireproof” plant. Even low-flammability species dry out, drop litter, and burn under extreme conditions. In the first five feet, restraint beats plant selection every time.
A Sample Zone 0 Landscape
Homeowners worry that compliance means a gravel moat. It does not. A well-composed ember-resistant perimeter can be genuinely attractive.
Picture a band of warm-toned decomposed granite along the foundation, broken up by a few large boulders and a run of flagstone stepping-stones. A weathered-steel edge separates it from the lawn beyond. Two or three widely spaced succulents in metal pots sit away from the wall.
Just past the five-foot line, in Zone 1, you concentrate the color — irrigated, spaced perennials and a specimen tree limbed up off the ground. The eye reads a designed landscape; the fire reads nothing to burn.
Fencing Is Landscaping Too
Most homeowners treat fencing as separate from landscaping, but in the ember-resistant zone it is one of the most important design decisions you will make. A wood or vinyl fence that connects to your house acts as a wick, carrying fire along its length into your siding.
In compliant zone 0 landscaping, the last five feet of any fence meeting the structure is noncombustible — a metal panel, a steel gate, or a masonry section — while the rest of the fence line can remain. Expect roughly $40 to $100 per linear foot for a metal section, or $500 to $2,000 for a noncombustible gate.
Decks, Planters, and Hidden Fuel
The five-foot zone extends under and around attached decks. Keep that space clear of vegetation, mulch, and stored items, and avoid combustible planters or trellises against the house.
Raised wood planter boxes along the foundation are a common oversight — they hold soil, plants, and combustible wood right where you need noncombustible ground. Replace them with metal or masonry, or relocate them beyond five feet.
Seasonal Maintenance
A noncombustible perimeter needs far less work than plant beds, but it is not zero. Keep it clean so wind-blown fuel does not accumulate.
- Blow or rake leaves and needles out of the gravel each season, especially before fire season.
- Pull weeds that sprout through hardscape.
- Keep firewood, bins, and seasonal decor outside the five-foot line.
- Trim any Zone 1 plants that grow toward the house.
Zone 0 Landscaping and the Law
These landscaping choices are not just aesthetic — they trace directly to California law. AB 3074 amended PRC 4291 to require the ember-resistant zone, and the Board of Forestry and Fire Protection is finalizing the enforceable standard. New construction complies first, existing homes about a year after adoption.
The rules apply to properties in the State Responsibility Area and Very High Fire Hazard Severity Zones under CAL FIRE’s 2025 maps. Alongside CBC Chapter 7A construction standards and broader wildfire legislation such as SB 896, the state is steadily raising the bar for the landscaped area closest to the home.

What Zone 0 Landscaping Costs
For a typical home perimeter, plan around these ranges:
- Converting mulch beds to gravel or pavers in the 5-foot band: $3 to $8 per square foot.
- Noncombustible fence section or gate at the house: $40 to $100 per linear foot.
- Full Zone 0 landscape retrofit — hardscape, fencing, deck clearance, plant removal: commonly $3,000 to $15,000.
Beyond survival, this work counts among the mitigation actions California’s wildfire-safety framework recognizes toward insurance eligibility and discounts.
DIY Versus a Professional
Plenty of Zone 0 landscaping is genuinely do-it-yourself. Pulling mulch, relocating firewood, and trimming back foundation shrubs are weekend jobs that pay off immediately.
Where a professional earns their fee is the permanent work: grading and installing hardscape that drains properly, cutting a noncombustible section into an existing fence so it looks deliberate, and confirming the finished perimeter will actually pass a defensible space inspection.
A wildfire mitigation specialist also sees the fuel you miss — the vine creeping up the eave, the vent sitting inches above a mulch bed, the deck skirt hiding a decade of leaf litter. That trained eye is often the difference between a yard that looks fire-smart and one that truly is.
Frequently Asked Questions
What is zone 0 landscaping?
It is landscaping the first five feet around your home with noncombustible materials so embers cannot ignite anything against the structure.
Can I have any plants in Zone 0?
The standard favors a plant-free band; at most, low, widely spaced, well-irrigated plants — never woody shrubs or vegetation touching the house.
What kind of mulch is allowed in Zone 0?
Only noncombustible “mulch” like gravel, crushed rock, or decomposed granite. Bark, wood chips, and rubber are not allowed.
What ground cover works best?
Gravel, decomposed granite, pavers, flagstone, and stone give a finished look while staying noncombustible.
Does zone 0 landscaping include my fence?
Yes. The five-foot fence section connecting to the house must be noncombustible, even though the rest of the fence can remain.
Can I keep raised planter boxes near the house?
Not wooden ones within five feet. Use metal or masonry, or move planters beyond the ember-resistant zone.
Is artificial turf okay in Zone 0?
Most synthetic turf is combustible and melts, so it is generally discouraged in the five-foot zone; gravel and hardscape are safer.
Will this make my yard look bare?
No. Thoughtful hardscape, boulders, and stone create a clean, designed look — and you can concentrate planting in Zone 1 just beyond five feet.
Is zone 0 landscaping required by law?
AB 3074 created the requirement; the enforceable regulation is being finalized, with new construction first and existing homes about a year after adoption.
Next Steps
Zone 0 landscaping is where wildfire defense and curb appeal meet: a clean, noncombustible perimeter that gives embers nowhere to land and keeps your maintenance low. You do not have to gut your yard — you have to clear and re-material the five feet that matter most.
The highest-impact place to start is the piece homeowners forget is landscaping at all: the combustible fence or gate connected to your house. Swapping that five-foot section for metal or masonry removes the clearest path for fire into your home. See how your property scores with our wildfire risk assessment tool.
