Clear zones. Safer homes. Defensible space can help protect your
home, your family and the firefighters defending your community.

Important:
Just Fences provides this page as a
general educational resource. We are fencing and construction
professionals—not legal, fire-code or insurance experts.
Regulations and local requirements may change. Confirm the rules
for your property with your local fire department, fire-prevention
authority, building department and insurance provider before
beginning work.
Defensible Space: Zones 0, 1 and 2
Zone 0: 0–5 feet
Ember-Resistant Zone
```
The area immediately surrounding the home, including attached
decks and the point where fencing connects to a structure.
Current guidance emphasizes removing combustible debris and
materials and using noncombustible surfaces wherever practical.
Zone 1: 5–30 feet
Lean, Clean and Green
Remove dead or dry vegetation, maintain plants and trees, and
create separation between potential fuels so fire is less likely
to move toward the structure.
Zone 2: 30–100 feet
Reduced Fuel Zone
Reduce the amount and continuity of vegetation and other fuels.
Required distances may be affected by property lines, slope,
terrain and local rules.

What California law is changing
California enacted Assembly Bill 3074 in 2020
and Senate Bill 504 in 2024. Together, these measures
amended Public Resources Code section 4291 and directed the
California Board of Forestry and Fire Protection to establish an
ember-resistant defensible-space zone within the first five feet
surrounding a structure—commonly called Zone 0.
Defensible-space obligations already apply to properties in
California's State Responsibility Area and to designated Very High
Fire Hazard Severity Zones within Local Responsibility Areas. Local
jurisdictions may also impose additional or more specific
requirements.
Current status:
As of June 2026, the statewide
Board of Forestry rulemaking process was still underway, with
draft language, public workshops and implementation details under
review. Do not rely on a proposed statewide deadline without
checking the latest state and local guidance.
What this may mean for fences and nearby structures
Current CAL FIRE guidance recommends replacing combustible fencing,
gates and arbors that are directly attached to a home with
noncombustible alternatives. Proposed Zone 0 rules may also affect
sheds, stored materials, vegetation, mulch and other combustible
items located within five feet of a structure.
Because every property is different, Just Fences recommends
requesting a defensible-space or home-hardening evaluation from
your local fire authority. An evaluation can help identify priority
work, confirm which rules apply and determine whether grant
assistance may be available.
How Just Fences can help
```
Just Fences can help homeowners evaluate fencing options near the
home, including transitions from wood fencing to noncombustible
gates or panels where appropriate. We also offer SaferWood Thermex-FR fire-retardant-treated wood
for suitable projects.
Final materials and installation details should be reviewed for
your specific property and confirmed with the authority having
jurisdiction. Contact us to discuss practical options for
improving safety without sacrificing the look and function of
your fence.

About the expected timeline
An April 18, 2026 report in the Los Angeles Times
described
the proposal then under review as allowing existing homeowners three
years after final adoption for certain landscaping changes and up
to five years for larger changes, such as modifying combustible
fencing and sheds. These time periods should be treated as
proposed—not final—until statewide regulations are adopted and your
local authority confirms how they apply.
