What is Home Ignition Zone (HIZ) and its primary focus areas?

• A. HIZ is the area around a home designed to prevent ignition from embers; focus areas include ignition-resistant construction, spacing, debris-free areas, and vegetation management within 0-100 ft
• B. HIZ is a zoning district
• C. HIZ stands for Home Insurance Zone
• D. HIZ refers to interior safety

Answer: (A)

The concept being tested is a protective area around a home designed to stop wildfire embers from igniting the structure. Its primary focus areas are ignition-resistant construction and exterior materials, features like ember-resistant vents, and ensuring spacing and clearance so flames and heat have fewer opportunities to reach the building. It also emphasizes keeping a debris-free zone to reduce available fuel near the home and managing vegetation within a 0–100 ft buffer to lessen ember landing and radiant heat exposure. This approach is about reducing ignition risk from embers around the house, not about zoning designations, insurance terminology, or interior safety.
