I previously lived in a condo building. I was unfortunately unlucky to have a really shitty neighbor (and I liked and got along well with everyone else on my floor). This neighbor, who was in her 40s, was apparently a trust-funder that came from a wealthy family and she didn't work, and thus would have parties at 4 AM on Monday morning (among others). She ruined my quality of life.

Originally the condo association gave her some minimal fines, but she was wealthy enough that it was just part of the cost of the party - I'm sure she had bottles of booze that cost more that $100 at her parties. It was only when the condo association changed the rules to implement an escalation series (i.e first violation was $X, second was $2X, third was $4X, etc.) that her behavior started to change.

I get that a lot of people hate HOAs and I understand the reasons, but $100 is essentially nothing to a lot of people in California, which means HOAs will essentially have no enforcement mechanisms. This is especially a problem in multifamily buildings like condos where people are literally living on top of one another.

IMO seems like just another well-intended CA regulation that will cause a lot of negative, poorly thought-out consequences. At the very least I think it would make a lot more sense to have the fine limit be based on the value of the house or something similar, and not a single rate for all of CA.
