It seems some houses that focused on fire safety survived the fire with minimal damage.

Metal roof, passive house so embers don’t get sucked in. Concrete walls around the property and plants that don’t contribute to the fire.
The house might cost an additional $100k to build compared to conventional. But it would make all that back on energy, roofing, and insurance costs- probably at the point the conventional home would need a roof replacement.
Builders don’t build such houses unless a client or building code mandates it.
Other sources say the house wasn’t a passive house but did have fire rated walls.
It seems like a lot of fire resistance can be created just by focusing on defensible space and having a concrete or metal fence. Then protecting the roof ventilation from fire (there are special screening materials that can be bought). Then using class A rated materials on the roof and then the exterior. Then metal framed windows instead of vinyl. Actually doesn't cost that much more- they should require it in building codes in these areas. The issue then is retrofit- insurers should probably require a defensible space in these high risk areas.
