And this is where insurance when allowed to set premiums, can help guide the market to the right solution. I don't believe LA has ever had a fire of this scale. Similar to that large fire in NorCal a few years back.

I am certain either through insurance requirements or simple price comparisons, homes that are getting rebuilt will be done so using modern standards. Its worth mentioning that a lot of this is not so much a concrete vs wood discussion. You can absolutely build a wood framed home that is fire resistant.
