Legal Question in Administrative Law in California

The law covering disposition of personal property remaining on a rental premises at the termination of the tenancy is contained in some detail in the Civil Code, primarily in sections 1980 to 1991. Basically, you must give the former tenant written notice of what's left behind, and the notice must be in more or less the format specified in Section 1984. The tenant has 15 days after personal delivery or 18 days after mailing of said notice to reclaim the property. If she fails to do so, the law contains provisions for public sale, or, if the property is worth less than $700, for dumping it. I'd recommend reading the provisions carefully, or as an alternative, get a paperback self-help law book from Nolo Press or equivalent on the general subject of landlord-tenant law in California. Keep in mind that the property still belongs to the tenant and she is entitled to the proceeds of sale (if there is one) less your costs to conduct the sale, storage, etc.
