Which yearly elements should be included in a WUI property maintenance plan?

• A. Roofing/gutter inspection, vegetation trimming, debris removal, water system checks, and access route reviews.
• B. Painting exterior walls, installing new siding, landscape lighting upgrades, and roof tile replacement.
• C. Commercial fire suppression system testing, building code updates, and permit renewals.
• D. Annual pest control, furniture replacement, and interior cleaning.

Answer: (D)

Yearly maintenance for WUI properties should reduce ignition sources and keep the interior environment safe while embers may approach from outside. Focusing on annual pest control helps prevent infestations that can compromise structure and create hidden fuel sources or pathways; replacing older, potentially more flammable furnishings reduces interior fuel load and the risk if embers enter the home; and regular interior cleaning minimizes clutter and combustible materials, making hazards easier to spot and mitigating internal fire spread. These routines support consistent, manageable maintenance that directly affects fire risk inside the home, complementing exterior defenses without relying on exterior tasks alone.
