What CAL FIRE And The State Of California Are Saying About Zone 0 Landscaping
What San Diego homeowners should know about the first five feet around the home
California is putting much more attention on the first five feet around a home during wildfire planning. This area is known as Zone 0, or the ember-resistant zone. CAL FIRE calls the first five feet the most important area around a structure because wind-blown embers can collect against walls, decks, fences, plants, and landscape materials and start a fire immediately next to the home.
For San Diego homeowners, the message is becoming clear: the area closest to the house should be designed differently from the rest of the landscape. That does not mean the property has to look barren. A well-planned Zone 0 Landscaping design can use attractive hardscape, thoughtful transitions, controlled planting, and good maintenance to create a landscape that still looks intentional.
What Exactly Is Zone 0?
Zone 0 is the area from zero to five feet around a structure. California law directed the State Board of Forestry and Fire Protection, working with CAL FIRE and the State Fire Marshal, to establish an ember-resistant defensible space zone in this area. The state also treats attached decks as part of the structure for Zone 0 purposes.
As of August 7, 2026, the California Board of Forestry and Fire Protection is still publishing draft Zone 0 rulemaking materials. That means homeowners should distinguish between the state's developing regulatory language and the practical wildfire-safety guidance CAL FIRE is already providing today.
What CAL FIRE Recommends In The First Five Feet
CAL FIRE's current defensible-space guidance is very direct about the first five feet. The agency recommends using noncombustible surfaces and reducing items that can ignite when embers land next to the home.
Use hardscape such as gravel, pavers, or concrete instead of combustible bark or mulch.
Remove dead and dying plants, weeds, leaves, needles, and other debris from areas next to the structure, including roofs, gutters, decks, porches, stairs, and areas underneath attached features.
Keep branches away from chimneys and stovepipe outlets.
Limit combustible furniture, planters, and other items on top of decks.
Move firewood and stored lumber farther away from the home.
Replace combustible Fencing, gates, or arbors that are attached directly to the house with noncombustible alternatives.
Consider moving trash and recycling containers, vehicles, RVs, boats, and other combustible items outside the immediate five-foot area.
Why The State Is Focusing So Heavily On Embers
The concern is not only a wall of flames reaching the house. Wind-driven embers can travel well ahead of a wildfire. When those embers land in dry mulch, leaves, wood fencing, vegetation, stored materials, or combustible items next to the home, they can create a small fire that exposes the structure to direct flame or radiant heat.
That is why California's approach starts at the house and works outward. Zone 0 is intended to reduce the chance that an ember has an easy fuel source immediately against the building.
What Materials Make Sense For A Zone 0 Landscape?
For homeowners, one of the most practical changes is replacing combustible groundcover directly next to the house with attractive noncombustible materials. Professionally designed Hardscape & Concrete can create clean walkways, patios, equipment access, and transition areas while also reducing combustible material near the structure.
Common design materials may include decorative gravel, natural stone, concrete, porcelain pavers, decomposed granite where appropriate, metal edging, masonry, and other noncombustible finishes. The goal is not simply to cover the first five feet with rock. The goal is to make that space look connected to the architecture and the rest of the landscape.
Does Zone 0 Mean No Plants Anywhere Near The House?
This is where homeowners need to be careful about the difference between current guidance and final statewide regulation. CAL FIRE's public guidance emphasizes keeping the first five feet clear and avoiding combustible vegetation and materials. Meanwhile, the Board of Forestry is still working through the detailed regulatory language.
From a design standpoint, we recommend thinking about the first five feet as the most restrictive landscape area and moving the stronger planting composition farther from the structure. A Plant Consultation can help select plants for the surrounding zones based on mature size, moisture needs, maintenance, and how much dead material they tend to accumulate.
This can work very well with Drought-Tolerant Landscaping. Fire-conscious design is not simply about picking a plant labeled 'fire resistant.' Plant spacing, maintenance, location, irrigation, and the amount of dead material around the plant are all important.
Zone 0 Is Only The Beginning: Zones 1 And 2 Still Matter
CAL FIRE divides defensible space into three areas. Zone 0 is the first five feet. Zone 1 continues from five feet to 30 feet from the structure, and Zone 2 generally continues from 30 feet to 100 feet or to the property line.
The design strategy changes as you move away from the home. Zone 0 focuses heavily on ember resistance. Zone 1 emphasizes keeping vegetation lean, clean, and green with proper spacing. Zone 2 focuses on reducing potential fuel and maintaining separation between vegetation.
A good Landscape Design Process should look at all of these areas together instead of treating the first five feet as an isolated strip.
Attached Wood Fences And Gates Deserve Special Attention
One detail CAL FIRE specifically calls out is combustible fencing, gates, and arbors attached to the home. A wood fence can become a pathway that carries fire directly toward the structure.
Where an existing fence connects to the house, homeowners may want to consider a noncombustible transition section using metal, masonry, or another suitable material. Our Fencing planning can coordinate that transition with the rest of the fence so the solution looks intentional rather than like an emergency modification.
Do Not Forget Drainage And Irrigation
Replacing planting and mulch with rock, concrete, or other hardscape changes how water moves around the home. That is why Drainage should be considered whenever a Zone 0 area is redesigned.
Water should not simply be trapped against the foundation because combustible mulch was removed. Grades, drains, downspouts, hardscape slope, and runoff paths still need to work correctly.
Irrigation also needs to be adjusted when planting areas change. Unused drip lines and sprinklers should not continue watering areas that have been converted to hardscape or rock.
Landscape Lighting Can Be Incorporated Without Adding Clutter
Zone 0 improvements can also be an opportunity to simplify and clean up the area around the house. Professionally planned Landscape Lighting can illuminate entries, steps, walkways, walls, and architectural details while keeping transformers, wiring, and fixtures organized.
When we redesign these areas, we want the fire-conscious improvements to look like part of a finished landscape rather than a collection of individual safety changes.
What Homeowners Should Do Right Now
You do not have to wait for every detail of the statewide Zone 0 rulemaking process before improving the area around your home. CAL FIRE is already recommending practical steps that make sense today.
Walk the first five feet around the entire house and attached decks.
Identify bark mulch, wood piles, dry vegetation, leaves, stored materials, and combustible items directly next to the structure.
Look closely at wood fences or gates that physically connect to the home.
Clean debris from gutters, roof edges, decks, stairs, and areas underneath attached structures.
Consider where gravel, pavers, concrete, or another noncombustible surface could replace combustible landscape material.
Review how changes will affect irrigation and drainage before removing or installing materials.
Check local fire authority, HOA, city, and county requirements that may apply to your specific property.
The Important Regulatory Point For California Homeowners
California has already established the direction: an ember-resistant zone within the first five feet around structures is part of the state's wildfire strategy. However, homeowners should be careful with articles that present every proposed Zone 0 detail as if it were already a final statewide rule.
As of August 7, 2026, the Board of Forestry's own website is still posting July 2026 draft Zone 0 regulatory materials. We will continue watching those requirements as they develop and adjust our designs when final standards or local requirements change.
How Nature's Elements Landscaping Approaches Zone 0
Our approach is to make wildfire-conscious improvements feel like landscape design, not simply vegetation removal. We look at the architecture, existing grades, doors and windows, walkways, irrigation, drainage, fencing, lighting, and the larger planting plan before deciding what belongs within the first five feet.
The result might include a decorative gravel band, new concrete or pavers, a walkway, masonry, noncombustible fence transitions, lighting adjustments, drainage improvements, and carefully located planting outside the most restrictive area.
