Legal Question in Landlord & Tenant Law in California

Landlord/Tenant law does not apply to the situation you describe. The law of "Bailments" applies. As an involuntary bailee, you must give reasonable notice that you want the goods retrieved, and notice of a reasonable time in which to collect them before you will dispose of them. What is "reasonable" is not specified in the law. So the safest bet is to so extra super reasonable that no one could conclude you were unreasonable, and then if the things are not gone, you can get rid of them. If you get money for them, however, you may only deduct any acutal provable costs to you of holding and selling them (and no, irritation is not a cost); the rest of the money has to be paid to the bailor.
