Zone 0 Ember-Resistant Defensible Space

Directs the Board of Forestry to adopt regulations requiring an ember-resistant zone with no combustible materials within 5 feet of structures in high fire hazard severity zones. Executive Order N-18-25 set a December 31, 2025 rulemaking deadline, but the Board paused and rulemaking continued into 2026 — new homes and remodels in fire zones will be directly affected.
