Fire resilience

Long-lived construction must account for wildfire exposure as well as ordinary weathering. Earlier durable-building discussions raised noncombustible materials, ember protection, and the relationship between a building and its landscape.

Treat the enclosure as a connected system

CAL FIRE’s home-hardening guidance addresses roofs, vents, windows, walls, decks, and other vulnerable elements. Defensible space complements building measures. A stone exterior by itself does not protect openings, the roof edge, or adjacent combustible features.

Questions for design

Element	Question
Roof and gutters	Can debris accumulate, and can it be removed safely?
Vents	Is the selected product appropriate for ember and flame exposure?
Windows and doors	What glazing, frame, and installation details are required?
Wall base and decks	Can nearby fuel expose vulnerable connections?
Landscape	How will vegetation, stored items, and maintenance affect exposure?
Service penetrations	Are enclosure openings detailed as part of the whole system?

Exterior fire shutters were an explored option in earlier discussions, not a chosen specification. Their operation, tested performance, attachment, and compatibility with required escape openings need evaluation.

What remains site-specific

Determine the applicable wildfire designation, current requirements, and approved products for the actual property. Material labels such as “metal” or “stone” are insufficient to establish a rated assembly.
