Zone Zero & Wildfire Landscaping

Zone Zero, also called Zone 0, focuses on the first five feet around a home and certain attached structures. Its purpose is to reduce materials that windblown embers can ignite close to the building. Creating this ember-resistant area is an important part of protecting a property from wildfire.

The statewide framework covers qualifying structures in State Responsibility Areas and Very High Fire Hazard Severity Zones within Local Responsibility Areas. Requirements depend on your property’s location, rather than its city name alone. Check the State Fire Marshal’s mapping tools and confirm your property’s designation and applicable requirements with the local fire authority. Local standards may be stricter.

The Board of Forestry reports that final administrative review is still underway. Its approved approach applies the new requirements to covered new construction once the regulations become effective. Existing properties have phased requirements, including changes within three years and additional work within five years, subject to the applicable agency’s schedule. Existing defensible-space obligations continue to apply. Visit the Board of Forestry’s Zone Zero information page for updates, and confirm your property’s deadlines with your local fire authority.

Not necessarily. The Board-approved framework distinguishes a noncombustible safety area closest to vulnerable building features from other portions of Zone Zero. Certain maintained, low-growing, non-woody plants may be allowed outside that safety area, subject to size, spacing and placement limits. Traditional foundation shrubs and hedges should be reviewed individually before deciding what can remain.

Not automatically. The Board’s guidance allows qualifying existing trees to remain when properly maintained. Pruning, clearance from roofs and chimneys, and removal of dead branches and accumulated leaves are important. We recommend assessing valuable trees individually and involving a qualified arborist when substantial pruning is needed.

These materials should not be treated as noncombustible landscaping. Wood products, rubber mulch and synthetic lawns can provide fuel near a building. For areas requiring noncombustible surfaces, we recommend considering appropriate stone, gravel or paving instead, with material selection and installation reviewed for the property’s requirements.

The approved framework targets combustible connections that can carry fire toward a home. It calls for a five-foot noncombustible section where a fence or gate attaches to, or comes within one foot of, a covered structure. It also restricts new combustible fencing within Zone Zero. It does not require wholesale replacement of every existing wooden fence.

Yes. The approved framework includes these attached features when determining the protected area. Measuring only from the house wall can overlook areas that need attention. We review the relationship between the building, attached structures and surrounding landscaping when planning improvements.

Absolutely. Our design approach can combine carefully selected stone, decorative gravel, paving, architectural details and appropriately located planting. The goal is to make the area near your home look intentional and complement its architecture, while preserving color, texture and greenery where appropriate.

Yes. We can incorporate proposed Zone Zero improvements into a broader pool and landscape project. This gives us an opportunity to coordinate paving, planting locations, drainage, irrigation and gate materials as one design. We can also identify work that should be prioritized and items that can be addressed in later phases.

No. Leaves, weeds and combustible debris can accumulate again, even on stone or paved surfaces. Regular maintenance remains essential. Zone Zero also complements the defensible-space requirements farther from the home; it does not replace applicable vegetation management in Zones 1 and 2.

Yes. We can review your existing landscape, discuss potential changes and develop a coordinated plan that considers wildfire exposure, appearance and everyday use.
