Let's say I either live (or know someone who lives) a stone's throw from this area, and know the lay of the land intimately. Plus, I (or this other person) listens to both local news on the radio, and a scanner that can pick up FD ground and air comms.
The update at this time: Evac orders rescinded. Fire surrounded, now mostly contained. No structures (homes) burned. I'm fairly confident the explanation given as to how this started (weed whacker) is correct. If the intention was to destroy someone or something with a brush fire, this is the wrong time of the year to try. No wind to speak of.
The attached picture circles the burned area. It is a very steep hillside, and loaded with native chaparral that loves to burn. All the local FD's were on this fire like flies on dung.
What is Q Research notable about this story is that the fire was located just south of Beverly Park, a large gated enclave of the super affluent. Consider it a prime suspect region for cabalists.
Who lives there? For instance, the film The Big Short about the 2008 housing bubble financial crisis, where a number of individuals strike it rich by betting against mortgage back securities? Yeah, one of those characters lives there.
Another character who lives there is very dig worthy (public info). I will share what I know about that person later.
