My Brother (21) Needs To Be Evicted Asap But I Don’t Know Where To Start (california)

My brother has been mentally abusive to my family for a couple of years now due to a mix of autism and nonstop smoking marijuana causing him to develop what seems to be BPD or something similar. I’m writing the post for my mother who is at her wits end and needs him gone asap.

We live in a smaller apartment in Southern California with my mom, me, him and my moms boyfriend. He doesn’t pay rent often and when he does it’s a mere 100$ left over from his weekly weed purchases. He makes it a point to avoid us and play his drums or guitar loud as possible at all hours of the day. When we ask him to quiet down he will slam his hands against his keyboard or just turn it up louder to piss us off and let us know who’s boss. When he’s sober and in his right mind he’s pleasant and enjoyable but we haven’t seen that version of him in years. He went to a rehab facility about 7 months ago and came back okay- only for him to start smoking immediately and going back to this awful cycle.

Our father lives about 15 miles away and is a self centered douche who has made it clear he has no intensions of taking my brother. That would be his only choice though if we did evict him hopefully.

My brother has been going to college for 3.5 years now and has managed to fail out of every class or pass them with a minimal score. He has a 1.5 gpa but tells us how he’s going to enroll into a nicer college this fall (9 months away) somehow despite his grades.

My brother also has a part time job that pays him very little that he stays at because he can’t get a drivers license.

I make this post to ask for advice on how to begin the eviction cycle. In california it seems remarkably expensive and complex. We’ve considered moving elsewhere to avoid having to fill out so much documents, but we’d like to stay where we are most of all.

Does anyone have legitimate advice?
