Fire-Resistant Siding in Cupertino
Honest answer: Cupertino is split. The flat valley grid is low wildfire exposure where fire-resistant siding is a low-regret default; the western foothill-edge parcels toward Regnart and Stevens Canyon carry genuine moderate exposure where it is a real decision. We won't apply one story to the whole city.
Flat grid low, western edge moderate
Most of Cupertino is low-exposure flat valley floor. The western foothill-edge lots are genuinely moderate — not extreme like deep-canyon mountain towns, but real — warranting Class A non-combustible cladding with hardened eaves, vents, and ground transitions. We characterize each parcel accurately.
Free on the grid, real on the Stevens Canyon edge
Flat-grid Cupertino (and its design-led rebuilds) gets Class A as an incidental benefit of the premium fiber cement it would choose for design anyway. The western Stevens Canyon / Regnart foothill-edge lots are the opposite — there non-combustible cladding plus hardened eaves, vents, and ground transitions is the actual scope, sized to the parcel.

FAQ
Fire-Resistant Siding in Cupertino — FAQ
It depends on the parcel — flat-grid Cupertino is low-exposure (low-regret only), while western foothill-edge lots carry genuine moderate exposure warranting hardened non-combustible detailing.
Moderate and real on the western foothill edge toward Regnart and Stevens Canyon; low on the flat valley grid. Not extreme like deep-canyon mountain towns.
No — on the Stevens-Canyon edge the premium fiber cement chosen for design is already Class A, so the protection is included where Cupertino actually faces foothill.
On foothill-edge parcels it can support insurability; we document materials and assemblies, though insurers set their own criteria. On the flat grid the effect is usually negligible.
