If the account holder is a tenant, and if the owner or landlord of the property or premises has made a written request for notice, the notice shall also be given to the owner or landlord.

A city utility, city enterprise, or combined city enterprise shall not withhold service from, or discontinue service to, a subsequent owner who obtains fee simple title of the prior property or premises unless such delinquent amount has been certified in a timely manner to the county treasurer as provided in subsection 4, paragraph “a”, subparagraphs (1) and (2).

If certification of such delinquent rates or charges is attempted subsequent to the date a transfer of the property or premises in fee simple is filed with the county recorder, the county treasurer shall return the certification to the city utility, city enterprise, or combined city enterprise attempting certification along with a notice stating that the delinquent rates or charges cannot be made a lien against the property or premises.

The notice shall be sent to the appropriate persons by ordinary mail not less than thirty days prior to certification of the lien to the county treasurer.
  d.  Residential rental property where a charge for water service is separately metered and paid directly to the city utility or enterprise by the tenant is exempt from a lien for delinquent rates or charges associated with such water service if the landlord gives written notice to the city utility or enterprise that the property is residential rental property and that the tenant is liable for the rates or charges. A city utility or enterprise may require a deposit not exceeding the usual cost of ninety days of water service to be paid to the utility or enterprise. Upon receipt, the utility or enterprise shall acknowledge the notice and deposit. A written notice shall contain the name of the tenant responsible for charges, address of the residential rental property that the tenant is to occupy, and the date that the occupancy begins. A change in tenant shall require a new written notice to be given to the city utility or enterprise within thirty business days of the change in tenant. When the tenant moves from the rental property, the city utility or enterprise shall return the deposit if the water service charges are paid in full. A change in the ownership of the residential rental property shall require written notice of such change to be given to the city utility or enterprise within thirty business days of the completion of the change of ownership.
