Steel frame, flame retardant insulation and cladding, rammed earth, .. these are all options.

Flammable trees well away from a leaf free clean guttered (or no gutter) house are also no compromise requirements.

Don't even have to go that far.

Wood framing is fine: make your cladding stucco would do a lot (or brick). You can even have siding as cement-base stuff is available:

You could have metal or clay roofing, but shingles with a Class A rating is available as well:

Which are almost definitely known to the state of California to cause cancer.

Yes absolutely, and as another poster pointed out, earthquake codes exist. Metal framing is probably a bit easier to adapt to the same earthquake codes that timber framing has.
