On second thought, I wouldn’t try to get the landlord to not renew the lease and offer money to the tenant to move. Single parent with kids, the laws are bent not in favor of you. Especially in CA….

And the landlord probably isn’t going to do shit for the reasons above…

if diplomacy doesn’t work and you are convinced of that…Why can’t you play loud music in the middle of the night or early morning right before school starts? Go buy a Chinese Opera CD or something like that. That high pitch squeal will probably do it…Just saying.
