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.
