In Washington State a washer and dryer are personal property. I would think you could call your State Attorney General's office tomorrow to find out if legal in CA too.
Your renters are probably legally tenants, check that out too, again your State Attorney General's office can answer that question. Your lender might be able to help them move, ask there as well. Some lenders are helpful with some relocation costs for renters.
Did you not disclosure their status at your house?
