Legal Question in Real Estate Law in California

This is a nightmare situation and sounds like you have a very unreasonable person as a tenant. (Of course, I haven't heard his side of the story.) If you have a written rental agreement that specifies that the home is rented "partially furnished" or something of this sort, I think you can tell the tenant "No" to most if not all of the demands. As to the box of personal items, can you have a neighbor or friend pick it up and keep it for you? The tenant may have a right, however unreasonable it may be to exercise the right, to be free from storing personal items that aren't part of the furnishings. As to flooring, etc., if the place was rented with wood flooring, it seems to me the tenant will have to accept it. I might also suggest that you might want to consider using a professional property manager to handle your rental in the future - for a fee of up to 10% of the rent they assume responsibility for finding tenants and dealing with them......many landlords find managers well worth it.
