Legal Question in Criminal Law in California

I don't think you'd get too far with that in and of itself (if that is the extent) ... but maybe if it is a pattern, the police would at least take a report. Good luck!

It's illegal to enter someone else's premises without their permission, even if the door is wide open. Being able to get into someone's home is not the same thing as being allowed to do it.

Like Ms. Hofmeister, I wonder if you have enough evidence to prove beyond a reasonable doubt that this is what happened. Perhaps you do. Or perhaps you have a viable civil claim, since civil claims have lower standards of proof. (You don't have to choose; it's perfectly fine to sue someone and to ask the authorities to prosecute them for the same act, if the law and the facts are both on your side.)
