What is Zone Zero?
Zone Zero (Zone 0) is the first 0–5 feet around a structure, an area where embers may accumulate and ignite nearby combustible materials. Reducing those fuels can help lower the risk of fire spreading to the building. Zone Zero is distinct from wider defensible-space treatment in Zones 1 and 2.
The California Board of Forestry continues rulemaking and Office of Administrative Law review as of November 13, 2026. Do not treat every proposed rule as already enforceable statewide. Local ordinances, fire-authority directions and hazard-zone designation may impose separate requirements.
Orange County: why jurisdiction matters
Fire authority, city and hazard-zone designations may vary from one property to another. Check the latest CAL FIRE maps and the relevant local fire department before treating a checklist as mandatory. Inland and hillside properties may have different exposures from coastal urban sites.
A landscape assessment can still identify practical maintenance priorities such as leaf-litter removal, vegetation touching buildings and combustible materials immediately beside walls.
A practical five-foot perimeter assessment
- Walk every building perimeter, attached deck, stair landing, exterior wall, garage interface and adjacent utility area.
- Record combustible mulch, leaf litter, dead vegetation, woody shrubs, stacked materials and plant growth contacting siding.
- Review fences, gates and attached structures that could carry flame or radiant heat toward buildings.
- Evaluate possible noncombustible surfacing such as gravel, pavers or decomposed granite where appropriate.
- Preserve drainage, accessible paths, utility clearances, soil stability, existing trees and site-specific landscape needs.
- Review design with the local fire authority and relevant code professionals before implementing regulated changes.
Site recommendations depend on jurisdiction and on current adopted rules. Nature Care offers landscape assessment and improvement scopes; approval or certification by a fire authority is not implied.

What is legally required in November 2026?
The Board of Forestry reports that the statewide Zone 0 package remains under final review with the Office of Administrative Law. State law directs creation of a five-foot ember-resistant zone in designated areas, but the final operative requirements and timing should be checked against publication and your local jurisdiction.
Some communities have existing local defensible-space, vegetation, brush-clearance or home-hardening rules. Check the local fire department separately. A hazard map indicates an area classification and does not by itself establish every maintenance duty.

Frequently asked questions
Does the same rule apply to Irvine and Newport Beach?
Applicable fire authority and mapped hazard areas can differ. Check each address and local jurisdiction.
Is Zone Zero identical to a turf-replacement rebate?
No. Zone Zero addresses ember ignition near structures; turf rebates encourage qualifying water-saving conversions. Program requirements may overlap but are not equivalent.
